RFC 6762 reserves .local for link-local hostnames, so a URL like http://my-host.local:port is always LAN-scoped. Without this, the non-local timeout ceilings kick in (180s stream stale) and abort slow-prefill requests before they return a first token — e.g. a 48K MiniMax session on a local exo cluster that takes ~3 minutes to finish prefill. The existing _CONTAINER_LOCAL_SUFFIXES covers .docker.internal / .containers.internal / .lima.internal for the same reason; this adds the Bonjour/Avahi equivalent. Existing test suite (test_local_stream_timeout, 29 cases including negative "remote" URLs) passes unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Editable / `pip install -e` installs put the source tree outside the managed-install path. The banner's repo resolution was checking ~/.hermes/hermes-agent first, which on a dev setup points at a stale secondary checkout that isn't loaded by Python — so the "upstream commits behind" count and commit hash in the startup banner reflected the wrong tree. Flip the priority: try the directory this module is actually loaded from first, fall back to ~/.hermes/hermes-agent only if that isn't a git repo. This keeps the managed-install case working unchanged while making the editable-install case honest. Also dedupe the resolution logic — check_for_updates() had its own inline copy; now it calls _resolve_repo_dir(). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The vendor-prefix policy allowlist already includes "custom" but never matched user-defined providers because their resolved id is the slug form custom:<name>. Normalising before the membership check stops the false-positive warning that fires whenever a custom provider serves a model whose canonical id contains a slash (e.g. mlx-community/...).

When every configured messaging platform fails to connect at startup (e.g. a single Discord bot token has been revoked), upstream marks the gateway as startup_failed and lets launchd/systemd restart it. With a stale credential this becomes a tight crash loop while cron and the local CLI are unable to use the gateway. Add run_without_messaging_platforms (default false, set in config.yaml). When true, the gateway logs the per-platform failures and continues running in cron-only mode — same path as "no platforms enabled". The existing reconnection watcher is still populated so the platform comes back if the credential is rotated in. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Reasoning / thinking models served via custom_providers (DeepSeek V4 Flash, Kimi-style local serves, etc.) can exhaust the generation budget on reasoning_content alone if no max_tokens is set, leaving the visible response empty. Hermes already supports per-model context_length under custom_providers[*].models.<id> — extend the schema with a parallel max_tokens key and have AIAgent.__init__ pick it up when no explicit max_tokens is passed by the caller. This avoids a CLI flag dance for every invocation and keeps the default-None contract for non-custom providers untouched. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Push the kitty keyboard protocol's disambiguate flag at TUI startup so terminals that support it (kitty, WezTerm, Ghostty, foot, Alacritty 0.13+, iTerm2 3.5+) emit a distinct CSI-u sequence for Shift+Enter instead of the bare \r they share with plain Enter. Pop on exit, plus atexit + SIGTERM handlers so the terminal is never left in enhanced mode after a crash. prompt_toolkit's KeyBindings.add() validates against the Keys enum, so registering <shift-enter> in ANSI_SEQUENCES alone wasn't enough; we splice a new ShiftEnter member into the enum's internal maps at runtime and map both the kitty and modifyOtherKeys sequences to it. On terminals that don't speak the protocol the push/pop are silently ignored, so Shift+Enter still acts as plain Enter — no regression. Override with HERMES_DISABLE_KEYBOARD_PROTOCOL=1.
Two related fixes for the auto-compaction path:
1. Summary prompt template (agent/context_compressor.py):
- SUMMARY_PREFIX wrapper now states unambiguously that EVERY
question/request mentioned in the summary was already handled
in the prior context window. The only active instruction is
the post-summary user message. Resolves a failure mode where
the assistant resumed old, dropped threads from `Active Task`.
- `Active Task` field defaults to "None.", explicitly forbids
inventing tasks from older requests, side questions, dropped
threads, or assistant clarifying questions.
- `Pending User Asks` section deleted — it duplicated `Active
Task` and reinforced the resume-old-threads behavior.
2. UI visibility (run_agent.py):
- Compaction was only printed via `_safe_print`, so TUI/gateway
clients had no signal it was happening. Route through
`_emit_status` instead so it reaches CLI + status_callback.
- Pre-compaction line now shows token count, message count,
and the model that will summarize.
- Post-compaction line shows before/after tokens, % saved, and
before/after message counts.
Add a Cost line to the per-session exit summary printed when the user quits hermes. Sums cost across the entire compaction lineage so the displayed total reflects the whole conversation rather than just the live tip's row. When the cost is < $0.01 it renders with 4 decimals so micro-spends are visible; otherwise it uses 2-decimal dollar formatting. The cost status (estimated/actual) is suffixed when it isn't 'actual'. Adds SessionDB.get_lineage_cost_usd(session_id) which walks parent edges back through compaction boundaries to find the lineage root, then forward via a recursive CTE through every compaction continuation, summing estimated_cost_usd. Delegate / branch parents are not traversed — those are different logical conversations.
Render an estimated-cost column for each session in the list output, formatted ($0.0000 / $0.000 / $0.00 / —) so zero-cost rows don't visually compete with real spend. Also fixes a long-standing bug in list_sessions_rich's compression- projection: when projecting a root session forward to its tip, the merged dict kept the root's estimated_cost_usd column (which only covers the pre-compaction turns) and ignored the tip's cost. List entries for compacted conversations now show the lineage-wide total via get_lineage_cost_usd, matching what the exit summary displays.
The exit summary line was:
Messages: 235 (14 user, 207 tool calls)
…which silently lumped two distinct things into "207 tool calls":
assistant turns that *requested* tool calls AND the corresponding tool
result messages. Assistant text-only turns weren't counted at all, so
the breakdown didn't add up to msg_count and looked broken.
Split into three honest buckets:
- user messages (role == "user")
- assistant messages (role == "assistant")
- tool invocations (sum of len(tool_calls) across assistant messages)
- tool result messages (role == "tool"), shown alongside as a sanity
check — should match invocations in well-formed transcripts
New format:
Messages: 235 (14 user, 17 assistant, 204 tool calls / 204 results)
No behavior change beyond the printed string; only `_print_exit_summary`
in cli.py is touched.
Without these, cost estimation for Opus 4.5/4.6/4.7, Sonnet 4.5/4.6, and Haiku 4.5 falls through the official-docs path and lands in fuzzy/fallback pricing, which silently mispriced sessions on the new models. All entries snapshot from https://platform.claude.com/docs/en/docs/about-claude/pricing as of 2026-05-03 (pricing_version="anthropic-pricing-2026-05-03"): Opus 4.5 / 4.6 / 4.7 — $5 in / $25 out / $0.50 cache-read / $6.25 cache-write per 1M tokens Sonnet 4.5 / 4.6 — $3 in / $15 out / $0.30 cache-read / $3.75 cache-write per 1M tokens Haiku 4.5 — $1 in / $5 out / $0.10 cache-read / $1.25 cache-write per 1M tokens (also added the dated 20251001 alias) Pure data addition — no code paths changed.
When a streaming API call hit a transient ReadTimeout / ConnectError, the retry loop printed "Reconnecting…" / "Reconnected — resuming…" and then restarted the stream via `continue`, never polling `_interrupt_requested`. A user pressing Ctrl-C during the multi-second silent reconnect window would appear to be ignored — the interrupt only fired once the next stream attempt either succeeded or definitively failed. Add an interrupt check immediately before each `continue` in both retry branches (mid-tool-call retry at ~7222 and the general transient-error retry at ~7295). On interrupt we emit a clear status line and exit the streaming worker the same way an exhausted-retries failure does (result["error"] = e; return), letting the outer retry/recovery layer decide what to do. Pure UX fix; no behavior change on the happy path.
The streaming poll loop already touched the gateway activity tracker every 30s while waiting for the first chunk, but produced zero user-facing output. With the default _stream_stale_timeout of 180s, a slow first-token (large context on Opus, local-provider prefill, etc.) showed nothing in the terminal until either chunks arrived or the 180s reconnect kicked in — three minutes of dead air that looks frozen. Add a visible status line on each heartbeat tick once we've been silent for >= _HEARTBEAT_INTERVAL (30s): ⏳ Still waiting on provider — 30s elapsed (model: claude-opus-4-7) ⏳ Still waiting on provider — 60s elapsed (model: claude-opus-4-7) … This piggybacks on the existing _last_heartbeat cadence — no new threads, no extra work. The activity tracker touch is unchanged.
…e mode
Pushing the kitty keyboard protocol's "disambiguate escape codes" flag
(>1u, which we enable at startup so Shift+Enter works) also reroutes
modified Ctrl+letter and Alt+key combinations through CSI-u sequences
instead of their legacy bytes. prompt_toolkit's stock ANSI_SEQUENCES
only knows the legacy mappings, so under kitty:
- Ctrl+C arrived as \x1b[99;5u (unknown), and the kb.add('c-c')
handler never fired — interrupt/exit broken.
- Option+Delete (Alt+Backspace) arrived as \x1b[127;3u and didn't
trigger emacs' backward-kill-word.
- Alt+b/f/d word navigation was similarly silent.
Extend register_prompt_toolkit_keys() to teach the parser the kitty
disambiguate forms for all 26 Ctrl+letter combos, plus Alt+Backspace
and Alt+letter as (Escape, key) tuples — matching the format the
existing emacs key bindings already register against. Verified with
Vt100Parser that Ctrl+C resolves to Keys.ControlC, Alt+Backspace
resolves to (Escape, ControlH), and Alt+b resolves to (Escape, "b").
Adds first-class support for Anthropic's server-side web_search tool
(web_search_20250305) so it works as the primary web search backend
when running against an Anthropic endpoint — billed against the user's
Claude.ai subscription via the same OAuth bearer Hermes already manages.
On non-Anthropic providers the existing local Tavily/Exa/Parallel
backend takes over unchanged.
Mechanism: tools opt in by including an `_anthropic_server_tool` block
in their schema (e.g. `{"type": "web_search_20250305", "max_uses": 5}`).
The marker travels through the registry as an opaque schema field; only
the Anthropic adapter reads it.
Three transport-layer changes:
1. convert_tools_to_anthropic — when the marker is present, emit the
server-tool spec verbatim instead of the function-shaped form.
Also: the OAuth/Claude-Code mcp_-prefixing pass skips server tools,
because Anthropic only intercepts them under their canonical names.
2. build_anthropic_kwargs — adds the matching anthropic-beta header
(e.g. web-search-2025-03-05) when the request includes a server
tool. Conditional, not in _COMMON_BETAS, so third-party Anthropic-
compatible endpoints aren't affected. Merges with existing
extra_headers (preserves fast-mode / OAuth / context-1m betas).
3. AnthropicTransport.normalize_response — captures server_tool_use
and web_search_tool_result content blocks into
provider_data["server_tool_blocks"], exposed via a new
NormalizedResponse.server_tool_blocks property.
4. _build_assistant_message — persists those blocks onto the assistant
dict, so convert_messages_to_anthropic can re-emit them verbatim
before text/tool_use blocks on the next turn (Anthropic rejects
re-submitted assistant messages where server_tool_use exists
without its paired tool_result).
Also updates check_web_api_key to consider Anthropic credentials a
valid backend, so the web_search schema is exposed even without a
Tavily/Exa/Parallel key.
Verified end-to-end against api.anthropic.com:
- convert_tools_to_anthropic emits {type: web_search_20250305, ...}
- extra_headers carries web-search-2025-03-05 alongside OAuth betas
- 200 response with server_tool_use + web_search_tool_result blocks
- usage.server_tool_use.web_search_requests=1 (subscription billing)
Previously `/reasoning` was a typed-arg slash command that exposed all six OpenAI effort tiers (none/minimal/low/medium/high/xhigh) regardless of model. On binary-thinking models like DeepSeek-V4-Flash that map any non-"none" effort to enable_thinking=True, showing all tiers is misleading — they all behave identically. Now: - `/reasoning` (no arg) opens an in-TUI modal picker, same up/down/ enter/esc pattern as the `/model` picker. Choices are filtered to what the active model actually supports. - DeepSeek/MiniMax-style binary-thinking models see just `none` and `on`. Other (OpenAI-style) models keep the full ladder. - Show/hide display toggles (`show`, `hide`) live alongside the effort levels in the same picker. - Typed form preserved for power users (`/reasoning none`, `/reasoning hide`, etc.) — delegates to a shared `_apply_reasoning_arg` helper. Layout, key bindings (up/down/enter/esc/ctrl-c), and rendering all mirror the existing `/model` picker so behaviour is consistent.
Earlier commit oversimplified DSv4 to a binary on/off menu. Looking at exo's wrapper (`_v4_reasoning_effort` in utils_mlx.py), DSv4 actually exposes four distinct levels: none → enable_thinking=False medium → enable_thinking=True (default depth, no effort hint) high → enable_thinking=True, reasoning_effort="high" xhigh → enable_thinking=True, reasoning_effort="max" `minimal` and `low` collapse to the same default tier as `medium` on DSv4, so we drop them from the picker to avoid misleading equivalent-but-different-named choices. MiniMax stays binary (`none` / `on`). Other model families keep the full six-tier ladder. Picker labels now include human-readable hints (e.g. "high (more thinking)").
Verified against the deepseek-ai/DeepSeek-V4-Flash HuggingFace model card. The card documents three reasoning modes: Non-think → "none" (fast, intuitive responses) Think High → "high" (default thinking; logical analysis) Think Max → "xhigh" (max reasoning; needs ≥384K ctx window) I had introduced a fabricated "medium" tier in the previous commit (9a37e677e) on the assumption that "default thinking with no effort hint" was a distinct level. Per the card it's not — it's the same as Think High. `minimal`/`low`/`medium` all collapse to Think High through exo's _v4_reasoning_effort wrapper. Picker now shows the three real modes with model-card-accurate hints. Also adds the ≥384K context recommendation in the xhigh hint label.
The 'high' label was wrapping in the picker panel because the parenthetical was too long. Tighten all three to a parallel short form that fits typical terminal widths: none — Non-think (fast) high — Think High (default) xhigh — Think Max (needs ≥384K ctx) Full descriptions live in the HF model card, which the docstring points at.
The custom-provider branch only emitted extra_body["think"] = False when reasoning was disabled. When users set a positive effort tier (e.g. `/reasoning high` on the exo-cluster custom provider running DSv4-Flash), the API call dropped the choice silently — exo logs showed enable_thinking=None on every request, the Hermes UI showed 'Effort: high', but the model behaved as if no effort was passed. Forward the tier at the top level for OpenAI-Responses-aware custom servers: • api_kwargs["reasoning_effort"] = "high" / "xhigh" / etc. • api_kwargs["enable_thinking"] = True / False Most servers ignore unknown top-level fields, so sending both is safe. exo picks up reasoning_effort, derives enable_thinking from it, and threads the tier into DSv4's chat template. The Ollama-style extra_body["think"] = False path is preserved for backward compatibility — both fire when reasoning is disabled.
…nown kwargs) Previous commit a425a9ee1 set api_kwargs["enable_thinking"] which the OpenAI Python SDK rejects with TypeError because it's not a recognized Chat Completions parameter. The request never hit the wire — Hermes errored out immediately before the first turn. Move enable_thinking into extra_body so the SDK passes it through opaquely, matching the existing extra_body["think"] pattern. reasoning_effort stays at the top level — that one IS a valid Chat Completions field (used by o-series models) so the SDK accepts it.
Hermes' default agent loop fires all tool_calls the model emits in one turn. For models like DSv4-Flash that contractually emit ONE <think> block per turn (per HF encoding spec) but are designed for multi-step reasoning chained across turns, this means the model front-loads ALL its reasoning before committing to N tool calls — no chance to adapt mid-flow when a tool returns surprising data. The /interleaved opt-in truncates assistant_message.tool_calls to just the first call before execution, forcing the loop to make a new API call after each tool result. Each new call gets a fresh <think> block, giving the model a chance to re-plan based on the prior result. Dropped tool_calls aren't lost — the model re-emits them next turn if still relevant. Off by default; ~2× wall time when on (each turn re-prefills slightly more, but the prefix cache fix carries most of the shared context). Wire-up: • CLI_CONFIG["agent"]["interleaved_thinking"]: bool = False • AIAgent(interleaved_thinking=...) constructor arg • AIAgent._execute_tool_calls truncates list[1:] when enabled • /interleaved [on|off] slash command, persisted to config
Without an entry in hermes_cli/commands.py, the slash dispatcher still routed the command but tab-completion (which iterates CommandDef entries) didn't surface it.
When a streaming response drops mid tool-call and we silently retry,
the partial preamble + tool-prep that already rendered to the terminal
stays visible above the retry. Previously the separator between dead
and live content was a single line ("⚠ Connection dropped mid tool-call;
reconnecting…"), which is easy to miss when scrolling back — the stale
preamble can read as the agent picking up new work *after* a turn
appeared to complete.
Two changes here:
1. Replace the one-liner with a heavy boxed banner that explicitly
labels the prior text as ABANDONED, names the exception type, and
shows the retry attempt counter. Scrollback now makes it obvious
which output is dead.
2. Also flush _reset_stream_delivery_tracking() on the no-text-yet
retry path. Previously only the mid-tool-call branch reset
tracking; a drop before any visible delta could leave the context
scrubber holding a partial-tag tail that carried into the retry.
Both paths now reset before reconnecting.
No behaviour change for successful streams or terminal failures (after
all retries exhaust); only the user-visible separator and the partial
internal state cleanup change.
…e progress Three feedback items rolled into one focused change: 1. Cost tracking — the per-child cost rollup at the end of delegate_task() already existed (Kilo-Org/kilocode#9448 port) but the user couldn't see anything about subagent spend until the parent's session footer at end of turn. Now we emit visible status: - Every 30s during a child run (heartbeat-piggyback): model · tool · iteration · elapsed · running tokens · running cost. - On each child completion: status icon · model · duration · tokens · cost. - On full delegate_task() return: N/M subagents ok · total duration · batch child cost · session running total. All routed through _emit_status() so the lines reach both CLI scrollback and TUI/gateway status channels (per the lifecycle visibility convention in the hermes-agent-internals skill). 2. Per-call model selection — added 'model' to the delegate_task tool schema at both the top level and inside tasks[]. Precedence: per-task → top-level → delegation.model config → parent's model. Lets the orchestrator right-size each child (Haiku for retrieval/grep, Sonnet for analysis, Opus for deep reasoning) without editing config.yaml. Plumbed through to _build_child_agent's existing 'model' kwarg — the credential resolution path already supports per-child models, this just exposes the knob. 3. Progress visibility — until now, a long delegate_task showed only the parent's spinner_text "🔀 delegate ... 506.2s" with no signal about what the subagent was doing. The heartbeat thread already polled child.get_activity_summary() for the GATEWAY's _touch_activity (so inactivity timeout doesn't fire), but it was invisible to the user. Now the same poll cycle also routes a human-readable line through _emit_status. Same pattern as the streaming-stall heartbeat fix (commit 03890b6c) — piggyback existing thread, no new cadence. Tests: tests/tools/test_delegate.py 121/121 pass. User-visible diff (during a 3-child delegate run): ┊ 🔀 [0] claude-haiku-4-5 · salesforce_fetch_case (iter 2/30) · 30s elapsed | 4,210↓/127↑ tok | $0.0008 ┊ 🔀 [1] claude-sonnet-4-6 · search_files (iter 5/30) · 60s elapsed | 18,332↓/892↑ tok | $0.0772 ┊ ✅ subagent [0] claude-haiku-4-5 · completed in 47.2s | 9,217↓/411↑ tok | $0.0019 ┊ ✅ subagent [1] claude-sonnet-4-6 · completed in 142.8s | 38,201↓/2,103↑ tok | $0.1462 ┊ 🔀 delegate done · 3 subagents ok · 603.2s · children=$0.4287 · session=$0.7912 Replaces the prior 1-line "🔀 delegate ... 506.2s" with no cost insight.
… and exit summary
Follow-up to 201fa3fd. User feedback:
- Per-tick cost on the heartbeat line was noisy and not actionable mid-flight.
- Want subagent spend visible in /usage AND in the on-exit summary, both
rolled up into the session total.
Changes:
1. Heartbeat line (tools/delegate_tool.py): drop tokens + cost, keep model +
tool + iteration + elapsed. Per-child completion line and delegate-done
rollup line still show tokens/cost (those are the actionable surfaces).
2. New per-session counters (tools/delegate_tool.py, populated alongside
the existing session_estimated_cost_usd fold-in):
- session_subagent_cost_usd: cumulative $ spent in delegate_task children
- session_subagent_input_tokens / session_subagent_output_tokens
- session_subagent_count: total children spawned this session
Additive across delegate_task() calls — same semantics as
session_estimated_cost_usd. session_estimated_cost_usd already includes
children, so don't double-count when displaying the total.
3. /usage (cli.py::_show_usage): when subagent counters are non-zero, print
parent-vs-children breakdown instead of a single "Total cost" line:
Parent cost: $0.0421
Subagent cost: $0.4287 (3 children, 71,549↓/4,545↑ tok)
Total cost: ~$0.4708
Falls back to the original single-line shape when no children ran.
`cost_result.amount_usd` from estimate_usage_cost() is now treated as
parent-only (it was always parent-only in practice but the label "Total"
was misleading once children rolled in).
4. Exit summary (cli.py::_print_exit_summary): adds a subagent breakdown
sub-line below the existing Cost line when children contributed:
Cost: $0.47 (estimated)
↳ subagents: $0.4287 across 3 subagents (71,549↓/4,545↑ tok)
Silent for plain sessions (matches existing exit-summary minimalism).
Tests: tests/tools/test_delegate.py 121/121 still pass.
Note: cost_result.amount_usd in /usage was always strictly the parent's own
spend computed from session_input_tokens/session_output_tokens, but the
prior "Total cost" label was technically correct only when there were no
children. After 201fa3fd's rollup, session_estimated_cost_usd is the real
total — and the new counters let us split it cleanly without reverse-
engineering from the parent counters.
…legation)
Wires ruflo's ~90 agent personas (researcher, coder, system-architect, etc.)
into delegate_task and adds a curses-driven /delegation slash command for
managing per-role model assignments.
New module: hermes_cli/ruflo_agents.py
- discover_ruflo_agents(): rglob for .md files under any .claude/agents/
subtree of the configured ruflo install (~/repos/ruflo by default;
overridable via delegation.ruflo_path or RUFLO_PATH). Skips legacy v2/,
node_modules, __tests__, README/MIGRATION_SUMMARY non-agents, and
flow-nexus/payments/templates categories (cloud-only personas stripped
from the lockdown build). Dedupes by basename — same agent name in
multiple ruflo subtrees collapses to one entry.
- RufloAgent dataclass with .name, .description, .category, .path, and
a .load_prompt() method that strips YAML frontmatter and returns the
markdown body (the actual system prompt).
- get_role_model_map() / set_role_model() / lookup_model_for_role():
config-backed dict at delegation.model_by_role. Inline YAML save (no
cli.py import to avoid circular deps); honors HERMES_HOME for tests.
delegate_task plumbing:
- Tool schema: new "agent_type" field at top level and per-task,
documenting the persona library and pointing at /delegation.
- _build_child_system_prompt(): when agent_type is set, prepends the
matching ruflo persona prompt as a "# RUFLO PERSONA: <name>" block
above the task/context sections. Unknown agent_type values fall
through silently.
- delegate_task: model precedence is now
per-task model > per-task role-map (delegation.model_by_role) >
top-level model > delegation.model > parent's model.
/delegation slash command (cli.py):
- No args → curses radiolist of all discovered agents grouped by
category. ENTER on an agent opens a second-stage model picker
(Haiku 4.5 / Sonnet 4.6 / Opus 4.7 / Clear / Cancel). ESC bails.
- /delegation <role> → second-stage picker for that role only.
- /delegation <role> <model> → typed pin (no picker).
- /delegation <role> clear → remove pin.
- /delegation list → print current map.
Saves persist to ~/.hermes/config.yaml's delegation.model_by_role.
Unknown roles (not found in ruflo) save anyway with a dim warning —
user may want to invent custom role names like "tanium-triage" that
aren't in ruflo's library.
Config schema (hermes_cli/config.py):
- delegation.model_by_role: {} (default empty dict)
- delegation.ruflo_path: "" (default ~/repos/ruflo)
Tests: tests/hermes_cli/test_ruflo_agents.py — 19 tests covering
frontmatter parser, discovery (filtering / dedupe / categories), prompt
loader, group_by_category, get/set role-model map, lookup helpers.
All 140 tests in the test_ruflo_agents.py + test_delegate.py suites
pass (no regressions in delegate plumbing).
Tested locally: `discover_ruflo_agents()` finds 90 agents across 23
categories on user's lockdown ruflo install (~110 raw → 90 after
dedupe + skip-categories).
…ses picker Two follow-ups based on user feedback after first ruflo /delegation usage: 1. Bug: typing `NousResearch#8` (or other Shift-digit / mouse / paste sequence) inside the curses radiolist exited the picker. Root cause: `key in (27, ord("q"))` matched ESC byte (27) which the terminal also emits as the leading byte of CSI sequences for unrelated keys. So a single ESC byte from a `NousResearch#8` keypress was treated as cancel. Fix in hermes_cli/curses_ui.py::curses_radiolist: when ESC arrives, briefly poll for a follow-up byte using nodelay() — if -1, it's a real lone ESC (cancel); otherwise drain the rest of the sequence and continue the loop. Removed the `27, ord("q")` tuple match; ESC is now its own guarded branch and `q` keeps its dedicated cancel path. Added explicit "any other key — silently ignore" comment so future drift doesn't reintroduce the bug. 2. Feature: curated default model assignments for all ~90 ruflo personas. New module-level dict ``SUGGESTED_ROLE_MODELS`` in hermes_cli/ruflo_agents.py mapping each known agent to one of three models based on what the persona actually does: - Haiku 4.5: retrieval / triage / scanners / monitors / lookup (researcher, scout-explorer, code-analyzer, issue-tracker, pii-detector, performance-monitor, etc.) - Sonnet 4.6: balanced default for code work, swarm coordination, github automation, day-to-day analysis (coder, tester, reviewer, all -coordinator/-manager swarm pieces, pr-manager, repo-architect, SPARC stages spec/pseudo/refinement, etc.) - Opus 4.7: deep reasoning, architecture, security, novel design, complex consensus (system-architect, security-architect, security-auditor, byzantine-coordinator, raft-manager, crdt-synchronizer, ddd-domain-expert, sparc-orchestrator, queen- coordinator, injection-analyst, safla-neural, etc.) New ``apply_suggested_defaults(overwrite=False)`` writes the map to ``delegation.model_by_role`` in one shot. Default mode preserves any existing user-customised pins; ``overwrite=True`` clobbers them. New slash command forms: /delegation defaults Apply curated defaults (preserve pins) /delegation defaults --force Apply, overwriting existing pins Tests: 5 new tests in test_ruflo_agents.py covering empty-fill, pin- preservation, force-overwrite, idempotence, and a sanity check that every suggested model is one of the three curated choices. 145/145 tests pass (was 140 before — added 5 new + no regressions).
Self-review of SUGGESTED_ROLE_MODELS turned up 9 mis-classified roles.
Adjustments below all justified inline with rationale comments.
Demoted from Sonnet → Haiku (orchestration glue, not reasoning):
- swarm-issue, swarm-pr, release-swarm, pr-manager
These are GitHub fan-out coordinators — they read state and route
work, but the actual reasoning lives in the workers they spawn.
Demoted from Sonnet → Haiku (high-volume runtime guardians):
- aidefence-guardian, claims-authorizer
Fire on every message in their respective pipelines; reasoning is
pattern-match scale, not deep. Haiku saves real money here.
Demoted from Opus → Sonnet (well-defined protocols, not novel design):
- crdt-synchronizer, gossip-coordinator
Implementing CRDTs or gossip protocols is mechanical once you know
the type. Sonnet handles this fine.
Demoted from Opus → Sonnet (orchestration of pipelines, not the work itself):
- safla-neural
Orchestrates SAFLA self-improvement loops; doesn't perform the
weight-level reasoning itself.
Promoted from Sonnet → Opus (genuinely deep reasoning):
- repo-architect: cross-repo architecture decisions
- reasoningbank-learner: trajectory pattern extraction is its entire job
- tdd-london-swarm: mock-driven TDD requires deep design reasoning
Tests: tests/hermes_cli/test_ruflo_agents.py — 24/24 still pass. The
existing "every suggested model is one of three known choices" sanity
test caught nothing because all moves were within the valid set.
To pick up the new defaults, users who already ran `/delegation defaults`
need to run `/delegation defaults --force` (since their existing pins
will otherwise be preserved, including the now-corrected ones).
Layer (b) on top of the curated map: the map stays as the default,
observed metrics get logged, the user can inspect them on demand and
optionally see heuristic re-tune suggestions. No auto-apply.
New module: hermes_cli/delegation_stats.py
- DelegationStat dataclass: role, model, status, exit_reason, duration,
in/out tokens, cost, api_calls, max_iterations, hit_max_iter, ts.
All fields optional with sensible defaults (forward-compatible
schema; readers ignore unknown keys).
- record(stat) -> bool: append-only JSON at
~/.hermes/delegation_stats.json (HERMES_HOME-aware). Atomic
rename-on-write, recovers from a corrupt file by rewriting fresh,
capped at 10k records (FIFO drop). Honors
HERMES_DELEGATION_STATS_DISABLED=1 for opt-out. Best-effort —
never raises, never blocks.
- load_all() -> list[DelegationStat]: reads + reconstructs records,
silently dropping malformed ones.
- aggregate(stats, *, since_ts, role) -> list[RoleAggregate]: groups
by (role, model). Untagged stats (agent_type omitted) bucket as
"(untagged)". Sorted by total spend desc.
- suggest_retunes(aggs, *, min_samples=5) -> list[Suggestion]:
heuristic re-tune hints. Promote on hit_max_rate ≥ 30% or
success_rate < 80%. Demote on success ≥ 95% AND avg_output < 1500
AND no max-iter hits, OR cumulative spend > $1 AND avg_output < 800.
Min 5 samples per role+model bucket; skips Haiku→below and Opus→above.
delegate_tool wiring:
- _build_child_agent: stash `agent_type` on the child as
`_delegate_agent_type` (alongside the existing `_delegate_role`).
- _run_single_child: after the existing per-child completion emit,
write a DelegationStat record. Uses child.max_iterations and api_calls
to compute hit_max_iter. Wrapped in try/except so any failure here
can't break the delegation itself.
CLI command (cli.py):
- /delegation stats → table: role, model, n, ok%, max%, avg
dur, avg out tok, total $.
Sorted by spend desc — most actionable
row first.
- /delegation stats --suggest → same table plus heuristic re-tune
hints (just text — user runs
/delegation <role> <model> to apply).
- /delegation stats --role X / --days N : filtering.
- Updated /delegation help docstring + commands.py subcommands hint
to include `stats`.
Tests: 25 new tests in test_delegation_stats.py covering record/load,
disable-via-env, corrupt-file recovery, aggregate grouping/filtering,
status counting, and all suggestion branches (promote/demote/no-op,
boundary conditions for unknown models / Haiku floor / Opus ceiling /
untagged exclusion / min_samples threshold). 165/165 pass overall.
User can ignore this entirely until they care; `/delegation stats`
shows nothing until subagents actually run, and even then the
suggestions only appear under --suggest.

New web provider that delegates web_search and web_extract to the
Claude Code CLI's built-in WebSearch / WebFetch tools, reusing the
user's existing Anthropic auth (via `claude auth login`). No extra
API keys to manage — search/extract becomes "free" for anyone with
a Claude Code subscription.
Wires into the existing web_tools dispatch:
* web_tools._get_backend / _is_backend_available recognise
"claude-code" alongside parallel/firecrawl/tavily/exa/searxng.
* web_search_tool and web_extract_tool route to
ClaudeCodeSearchProvider / ClaudeCodeExtractProvider.
* check_web_api_key acknowledges the backend when explicitly
configured but does NOT auto-detect — the bare presence of the
`claude` CLI on PATH shouldn't silently claim availability.
* hermes_cli/tools_config.py registers a setup-UI entry under web
backends with no required env vars.
Provider shells out to `claude -p --bare --output-format json
--json-schema` so we get a structured envelope and predictable
result shape, and skips hooks/plugins/auto-memory on the inner
Claude run.

_repair_tool_call_name's normalize-and-fuzzy-match path correctly resolved Claude Code canonical names (Bash, Read, Edit, Write, Grep) back to their hermes equivalents, but every hit logged a "🔧 Auto-repaired tool name: 'Bash' -> 'terminal'" line — noisy and misleading on the OAuth path where these aliases are the *expected* shape, not a model mistake (cc_aliases.replace_with_cc_canonical swaps them on the outbound side for billing-classifier parity). Add a CC-canonical fast-path that consults agent.cc_aliases.CC_TO_HERMES before any normalization and short-circuits on exact (case-sensitive) match. Mark the repair as silent via a fresh _last_repair_silent flag that the dispatcher checks before printing the auto-repair line, so fuzzy/typo repairs still surface but well-known CC aliases pass through quietly.

New laptop-side subcommand that POSTs a prompt to a remote gateway's
/v1/runs endpoint, prints the returned run_id, and exits. Lets the
laptop close while the run continues server-side — the original
motivation is the LXC gateway that holds a long-lived setup-token,
so jobs survive my laptop sleep cycles.
Resolution chain (precedence high → low):
--gateway-url / --api-key flags
HERMES_GATEWAY_URL / HERMES_GATEWAY_API_KEY env vars
API_SERVER_KEY env var (fallback so the same vault key the gateway
uses also works on the client)
~/.hermes/.env values for the same names
defaults: http://172.16.0.50:8642 (the homelab CT IP) and no key
Prompt source: positional args (joined), --file PATH, or stdin.
Optional --tail attaches to /v1/runs/{id}/events SSE stream until
end-of-stream; ctrl-C detaches without stopping the run, matching
the fire-and-forget model. --tail-run RUN_ID skips submission and
just tails an existing run. --quiet prints only the run_id for
shell substitution.
Wire-up:
* hermes_cli/submit.py — new module, no top-level imports of httpx
so `hermes --help` etc. don't pay the import cost.
* hermes_cli/main.py — cmd_submit thin wrapper, submit_parser
registration with set_defaults(func=cmd_submit), and an entry
in _BUILTIN_SUBCOMMANDS so the plugin-discovery fast-path skips
eager imports for `hermes submit ...` invocations.
* tests/hermes_cli/test_submit.py — 15 unit tests covering
target resolution precedence, prompt sourcing, HTTP shape
(Bearer header conditional on key, instructions passthrough),
401 error UX, 5xx propagation, and the quiet/normal print modes.
Discord-side submission (so the user can fire jobs from a phone)
is a separate change to gateway/platforms/discord.py — out of
scope here.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
… api_server
Adds a /submit slash command on the discord adapter that mirrors the
new `hermes submit` laptop CLI: takes a prompt, POSTs it to the
api_server adapter on localhost:8642 (same box, no network hop),
returns the run_id immediately, and spawns a background watcher
that polls the run until terminal and edits the reply with the
result. Lets the user fire jobs from a phone DM and walk away.
UX: one message per run, edited in place (no thread spam). Initial
reply is `🚀 Submitted run <run_id> — working...`. On completion the
message becomes the output (truncated to fit Discord's 2000-char
limit) plus a footer `— ✅ done in Xs · N tokens · run <run_id>`.
On failure: `❌ run <run_id> ended in <status>` with the error
breadcrumb. On 1h timeout (e.g. stuck run): the watcher detaches
with an `⏱ still running, detaching` message, and the run continues
on the gateway.
Implementation:
* `_submit_run_via_local_api(prompt)` — async POST to /v1/runs,
reads API_SERVER_KEY + API_SERVER_PORT from env. Returns parsed
body or None on failure (logged).
* `_watch_run_and_edit_message(message, run_id, started_at,
poll_interval, max_wait_seconds)` — async polling loop; checks
/v1/runs/{id} every `poll_interval` seconds (default 5s). On
terminal status renders the result and edits the message.
Polling beats SSE here: simpler, more robust to network blips,
and we only update on milestones anyway.
* `_safe_edit_message(message, content)` — small helper, swallows
edit exceptions so callers stay reentrant.
* `slash_submit` — defers the interaction non-ephemerally so the
reply persists in the channel, dispatches to the helpers above,
and stashes the watcher task on `_submit_watch_tasks` so asyncio
doesn't garbage-collect it mid-poll.
Auth: reuses `_check_slash_authorization` so /submit is gated by
the same allowed-users / allowed-roles config that the existing
slash commands use. The HTTP call to the api_server uses the same
API_SERVER_KEY env var the api_server platform already reads at
startup — single source of truth.
Tests: tests/gateway/test_discord_submit.py covers the two pure
helpers (the slash-command flow itself is integration-shaped):
HTTP submission shape (URL, Bearer header, body), missing-key
behavior, 5xx propagation, completed-output rendering with token
footer, failure-state breadcrumb, long-output truncation under
the 2000-char ceiling, and the timeout-detach path.

Discord adapter's /submit was hardcoded to call http://127.0.0.1:{API_SERVER_PORT}/v1/runs, but the api_server adapter honors API_SERVER_HOST too — and on the LXC we deliberately bind it to the homelab IP (172.16.0.50) so the laptop CLI can reach it. Result: /submit on Discord 503'd with `Connection refused` to 127.0.0.1:8642 because no listener was on localhost; the listener was on 172.16.0.50:8642 only. Read API_SERVER_HOST + API_SERVER_PORT in a single _local_api_base_url() helper, default to 127.0.0.1 when unset (matches api_server's own DEFAULT_HOST behavior), use it in both _submit_run_via_local_api and _watch_run_and_edit_message. Adds a regression test that sets API_SERVER_HOST=172.16.0.50 and asserts the resulting URL targets that host instead of localhost. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Pairs with the homelab/main commit that put `tailscale serve` with a Let's Encrypt cert in front of api_server on hermes-gw-01. The CT is now reachable at https://hermes-gw-01.tail19c543.ts.net for any client on the tailnet, and api_server itself is loopback-only (so the old http://172.16.0.50:8642 default no longer works at all — that bind moved to 127.0.0.1). Updates DEFAULT_GATEWAY_URL, the module docstring, and the --gateway-url help text. Anyone running plain `hermes submit "prompt"` on a tailnet-attached laptop gets TLS to a real LE cert by default; no env override needed. Existing precedence chain (flag > env > ~/.hermes/.env > default) is unchanged, so non-tailnet clients can still point at a different URL via HERMES_GATEWAY_URL.

Phase-6 left api_server with a single bearer token shared by laptop CLI
and discord adapter. That meant audit visibility couldn't distinguish
the two and revoking one took the other down. This commit adds optional
multi-principal auth + a structured audit log, fully backwards-compatible
with the legacy single-key path.
API_SERVER_KEYS_FILE (env / extra.keys_file)
Path to a YAML or JSON file mapping {principal_name: bearer_token}.
Loaded once at adapter init. _check_auth walks the map with
hmac.compare_digest against every entry in constant wall-clock
(no early exit on match) and, on success, attaches the matched
principal name to the request via `request["principal"]`. Empty /
missing / unparseable file → empty map → behave as if unset.
API_SERVER_AUDIT_LOG (env / extra.audit_log)
Path to an append-only JSON-lines audit log. /v1/runs POST writes
one record per submission with (ts, event, run_id, principal,
prompt_sha256, remote). Prompt content is *not* logged — only its
SHA-256 — so audit ingest can correlate runs without secret-leak
risk. Empty → no-op. Write failures swallowed (audit must never
break a real run).
Compatibility
* Legacy single-key path (API_SERVER_KEY / extra.key) unchanged.
Matching that key resolves to principal `default`. A keys-file +
legacy-key combined deploy is supported and tested.
* No keys configured at all → request tagged `anonymous` (matches
today's "no auth required" local-only fallback).
Discord adapter
Added `_local_api_bearer()` that prefers HERMES_DISCORD_API_KEY (so
/submit shows up under principal `discord-adapter`), falling back to
API_SERVER_KEY for back-compat. Both _submit_run_via_local_api and
_watch_run_and_edit_message route through it. New test asserts the
preference order.
Tests
tests/gateway/test_api_server_principals.py: 20 cases covering
_load_principals_map (empty / missing / JSON / YAML / non-mapping /
garbage entries), _check_auth (no-keys / legacy hit / legacy miss /
principal hit / both-modes / unknown bearer / missing header), and
_write_audit (no-op / writes JSONL / appends / swallows OSError).
Plus the new discord-side preference test.
Total: 20 new + 1 added discord-side = 21 added. Existing 179
api_server tests still pass.
Operator workflow on the LXC (separate homelab/main commit lands the
ansible bits):
vault: vault_hermes_gw_api_key_<short_name>: "<openssl rand -hex 32>"
templates/api_keys.yaml.j2: add a `short-name: "{{ vault_...... }}"` line
env.j2: API_SERVER_KEYS_FILE=/etc/hermes-gateway/api_keys.yaml
Restart the gateway. New principal lights up; audit log reflects it
on the next /v1/runs POST.

…se 8)
`hermes submit` + `/submit` are still keyboard-driven — to use them I
have to remember syntax and translate intent into a CLI invocation.
This commit ships a stdio MCP server (`hermes mcp-gateway`) that
exposes the gateway's run API as model-callable tools, so Claude (or
any MCP client) can just decide to delegate a task without me dropping
into a terminal.
Tools:
submit_task(prompt, instructions=None)
POST /v1/runs → returns {ok, run_id, gateway, status_url,
events_url, initial_status}. Fire-and-forget; caller polls.
get_run_status(run_id)
GET /v1/runs/{id} → returns the full run record (status, output,
usage, timestamps) flattened under ok=true.
tail_run_events(run_id, max_events=30, timeout_seconds=10)
GET /v1/runs/{id}/events → reads up to max_events SSE frames or
until the deadline, then detaches and returns. The run keeps
going server-side regardless.
stop_run(run_id)
POST /v1/runs/{id}/stop → idempotent kill.
list_recent_runs(limit=20)
Tails /var/log/hermes-gateway/audit.log over SSH and returns the
parsed JSONL records. Useful for "what was I delegating yesterday".
Config resolution mirrors `hermes submit`: HERMES_GATEWAY_URL +
HERMES_GATEWAY_API_KEY from env, then ~/.hermes/.env, then the
hardcoded default (https://hermes-gw-01.tail19c543.ts.net). So the
MCP server picks up the same bearer the laptop CLI already uses
without needing Claude Code's `env:` block populated. The audit
log will tag MCP-originated runs under whatever principal that
bearer resolves to (`default` today; cleaner to mint a
`laptop-claude-mcp` principal later).
Wired via `hermes mcp-gateway` subcommand in main.py (and the
_BUILTIN_SUBCOMMANDS allowlist so the plugin-discovery fast-path
skips the eager imports). Adding to Claude Code is one command:
claude mcp add hermes-gw --scope user -- hermes mcp-gateway
After which `mcp__hermes-gw__submit_task` etc. show up on session
start. Built on FastMCP (already a dep via the agent's MCP client
support); stdio transport; no new pyproject entries.
Smoke-tested end-to-end:
initialize → serverInfo: {name: hermes-gateway, version: 1.26.0}
tools/list → all 5 tools with descriptions
tools/call submit_task → run_id returned
tools/call get_run_status (8s later) → status=completed,
output="mcp-works", 12947 tokens

Adds a stdio MCP shim that proxies to Anthropic's claude.ai MCP proxy
using Claude Code's existing OAuth token (from ~/.claude/.credentials.json
or the macOS Keychain on Claude Code >=2.1.114). Lets Hermes reuse
whichever connectors Claude Code already has wired (Slack, Notion,
PagerDuty, Microsoft 365, Stack Overflow Teams, etc.) without
re-authenticating each one separately.
Previously this lived as a hand-maintained file under ~/.hermes/scripts/
on a single machine with no version control, plus two drift-prone copies
inside skill references. Lifting it into tools/bridges/ gives it a
canonical home, makes the import path stable
(`tools.bridges.cc_proxy_mcp`), and lets users wire it without
hard-coding absolute paths:
mcp_servers:
slack:
command: python
args:
- -m
- tools.bridges.cc_proxy_mcp
- --connector
- slack
timeout: 180
The script itself is unchanged behavior-wise from the live copy: per-request
token refresh via FreshBearerAuth, cross-process fcntl lock on the creds
file to serialize refreshes across simultaneous shim startups, 24h
~/.hermes/cache/cc_proxy_servers.json cache to avoid a list_servers storm
on cold start, and OAuth recovery on upstream 401.

…citation
Closes the warm-tier feedback loop without requiring the agent to remember
to call memory(action="feedback") after every recall.
Mechanism (asymmetric, upvote-only):
1. run_conversation() binds session_id to a contextvar at turn start.
2. WarmStore.recall / recall_related stash returned fact_ids + content
fingerprints in a per-session sliding window.
3. After the assistant's turn, on_turn_end() fingerprint-matches the
response against the recall window and fires
warm.record_feedback(fact_id, helpful=True) on cited facts.
4. Asymmetric — NEVER auto-downvotes. Silence != unhelpful. Explicit
downvotes still require memory(action="feedback", helpful=False).
Design notes:
* Fingerprint = 4-word run of distinctive (digit/uppercase/long-non-
stopword) content tokens, lowercased substring match. Conservative
by design — facts without distinctive content can't be auto-credited.
* Once-per-session dedup prevents double-counting when the same fact
surfaces in multiple recalls.
* Window ages out after recall_window_turns (default 3).
* ContextVar binding (vs threading session_id through memory_tool.py)
avoids touching the two memory-bypass blocks in run_agent.py — the
recurring bug surface documented in
software-development/hermes-agent-internals/references/memory-tool-bypass-dispatch.md.
* Best-effort everywhere — every entry point is try/except wrapped so
audit failures can never break a recall call.
Config (~/.hermes/config.yaml), default OFF:
memory:
auto_feedback: true
recall_window_turns: 3
min_fingerprint_words: 4
max_facts_per_session: 200
Audit motivation: before Phase 3, ZERO of 169 (later 486) warm facts had
helpful_count > 0. The trust_score column was locked at 0.5 for every
fact and the recall ranker was pure BM25 + retrieval_count. This commit
is the difference between "every recall is a fresh keyword grep" and
"the ranker learns which facts I actually consult."
Tests: 32 new (tests/tools/test_memory_auto_feedback.py), covering
fingerprinting, record_recall, on_turn_end match/miss, asymmetric
behavior (no auto-downvote), once-per-session dedup, window aging,
disabled-by-default config gate, contextvar binding, and the
WarmStore.recall hook.

…plier)
Background — Anthropic's tool_search_tool_*_20251119 server tool is the
default Hermes mechanism for deferred MCP tool loading. It bills the FULL
prompt context once per server-tool iteration within a single API call.
Stacking two tool_search calls in one turn = 3x prompt billing. Observed
in agent.log forensics from 2026-05-13 (case 00271597 session):
406K-token request billed as 1,219,284 tokens (3.00x), triggering forced
context compaction mid-debug. Across 14 historical bloat events: exact
integer multipliers (2x / 3x / 4x), matching the count of server-tool
iterations per call.
This change adds a Hermes-side client equivalent. Selected by new config
key tool_search.mode:
client_side (default for new installs)
Stubs are regular tool entries (no defer_loading flag), no server
tool prepended. Model discovers full schemas via the new
hermes_load_tools tool — a normal client-side tool dispatched out
of the agent loop. Each discovery is one normal round-trip, billed
once at normal rates. No multiplier.
server_side (legacy)
Existing Anthropic server-tool behavior, preserved unchanged for
OAuth / Claude-subscription users whose billing classifier scores
wire bytes (per the design comment in _apply_tool_search). Opt-in
via /toolsearch server_side.
Back-compat: a config with `enabled: true` and no `mode` key now
defaults to client_side (the safer behavior for any API-key user).
Existing `enabled: false` is unchanged.
Implementation:
tools/hermes_load_tools.py (new)
Registry definition + handler. Handler validates names against the
registered universe, mutates the agent's _promoted_tools set, returns
JSON with four buckets (loaded / already_loaded / already_eager /
unknown) and a next-step hint for the model.
agent/anthropic_adapter.py
_apply_tool_search rewritten with mode-aware logic. Both modes share
deferral policy (additional_eager / additional_deferred /
defer_mcp_tools). client_side mode skips the defer_loading flag and
the server-tool prepend; honors a new promoted_tools set so already-
discovered tools ship their full schema.
run_agent.py
* self._promoted_tools: set[str] = set() initialized per agent
* _build_tool_search_config() emits new "mode" and "promoted_tools"
keys (back-compat default = "client_side")
* _currently_deferred_names() helper mirrors the deferral policy so
hermes_load_tools can classify requested names accurately
* Two new agent-loop dispatch branches (parallel to todo / memory /
delegate_task pattern) for hermes_load_tools
model_tools.py
hermes_load_tools added to _AGENT_LOOP_TOOLS so handle_function_call
routes it back to the agent loop instead of the registry safety net.
hermes_cli/config.py
DEFAULT_CONFIG.tool_search gains "mode": "client_side"; docstring
rewritten to describe both modes + the multiplier evidence.
cli.py
/toolsearch command exposes the new mode flag with shorthand
(client_side / server_side / mode <m>) plus a warning print when
enabling server_side.
tests/agent/test_apply_tool_search_modes.py (new, 16 tests)
Mode-aware stub generation, promoted_tools bypass, server-tool
prepend only in server_side, back-compat for missing/invalid mode,
all/none-deferred safety guards.
tests/tools/test_hermes_load_tools.py (new, 12 tests)
Handler bucket logic, registry round-trip, safety-net handler error
contract.
Validation: 6,148 existing tests still pass (tests/agent + tests/tools +
tests/cli + tests/hermes_cli + tests/run_agent + tests/test_model_tools).
28 new tests pass. Static schema verification confirms client_side stub
fields (name + description + input_schema) are all declared
anthropic.types.ToolParam fields — defer_loading is properly optional.
Trade-off: client_side adds one round-trip per never-before-used MCP
tool per session (the discovery call). The model can batch by passing
multiple names to hermes_load_tools(names=[...]). In exchange, prompt
token billing per call is bounded by 1x and known precisely from the
message_start usage event — no more 2x-4x surprise growth.
drop_orphan_server_tool_uses_in_storage was scanning only
tool_search_tool_*_tool_result blocks when collecting paired-result
IDs. web_search_tool_result was invisible to it. So when an assistant
message contained a healthy server_tool_use + web_search_tool_result
pair, the function decided the server_tool_use was unpaired and
DROPPED it, leaving the result block orphaned forever. Every
subsequent API call then 400'd:
unexpected `tool_use_id` found in `web_search_tool_result` blocks:
<id>. Each `web_search_tool_result` block must have a corresponding
`server_tool_use` block before it.
Fix both audits (storage + outbound wire) to:
* recognise web_search_tool_result as a paired-result type
* drop orphans in BOTH directions (use without result, result
without use)
Verified against session 20260513_093942_d374cc, which this function
had wedged exactly as described. Existing
session_20260509_145003_c5e465 (the tool_search-side orphan that
motivated the original sanitizer) still recovers.
Three pre-existing roundtrip tests fed lone *_tool_result blocks with
no matching server_tool_use through the fixture — an unrealistic
shape Anthropic itself would have 400'd on. Updated the shared
_build_assistant_msg fixture to auto-inject a paired server_tool_use,
matching real responses. Added 8 new regression tests in
TestDropOrphanServerToolUsesInStorage covering: healthy pairs survive
both families, orphan use drops, orphan result drops (the new
direction), mixed scenarios, splits across messages, and end-to-end
wire-shape validation.

Follow-on to the symmetric orphan audit. After dropping an orphan web_search_tool_result block, text blocks in the same message can retain web_search_result_location citations whose encrypted_index referenced the now-missing result. Anthropic rejects the next request with: messages.<N>.content.<i>.citations.<j>: Could not find search result for citation index. The encrypted_index is opaque, so we match on URL: a citation is stale iff its URL has no surviving web_search_tool_result block anywhere in the message list. Phase 3 runs unconditionally — it must also rescue sessions corrupted by a prior buggy run that dropped result blocks without touching citations (e.g. session 20260513_093942_d374cc post-Phase-2). Applied to both: * drop_orphan_server_tool_uses_in_storage (persist-time) * convert_messages_to_anthropic (wire-time) Tests: 4 new in TestStaleCitationPruning covering pure-stale pruning, surviving-block tolerance, mixed citations, and the end-to-end wire path. All 58 roundtrip tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Follow-up Once Phase 2 drops orphan server-side blocks and Phase 3 strips stale citations on the trailing assistant message, the thinking-block signatures on that same message stop validating. Anthropic specifically forbids any modification — including removal — of thinking blocks on the latest assistant message: The existing Fix: storage-time Phase 4 detects whether Phase 2/3 touched the last assistant message. If yes AND that message carries thinking blocks, scrub its persisted Anthropic artefacts ( Only the trailing assistant message gets scrubbed. Earlier messages with modified blocks still go through the normal request-build downgrade path (unsigned thinking → text) without tripping the latest-message rule. Tests: Verified against session |

Four cleanup changes to reduce fork divergence from run_agent.py and
agent/agent_init.py, plus tooling and documentation to make future
upstream merges easier.
1. ForkForwardersMixin (agent/fork/_mixin.py)
- 12 thin forwarder methods moved out of AIAgent (run_agent.py) into
a mixin under agent/fork/.
- AIAgent now inherits: ``class AIAgent(ForkForwardersMixin)``.
- MRO is ``[AIAgent, ForkForwardersMixin, object]`` — all callsites
and test patches that expect ``agent._method()`` keep working.
- ``_RISKY_TOOL_NAMES`` class attribute also re-exported via the mixin.
- Net: run_agent.py loses 55 LOC of fork-specific code. Future
upstream changes to run_agent.py can no longer conflict on these
forwarders because the lines don't exist there anymore.
2. fork.<module>.init_state(agent)
- Each fork module now exposes ``init_state(agent)`` that sets the
module's own instance state.
- agent_init.py collapses a 40-line block of fork state initialization
into a 6-line loop over the fork modules.
- Net: agent_init.py loses ~30 LOC of fork-specific code, ownership
of fork state moves to the modules that use it.
3. scripts/fork-merge-plan.py
- Pre-merge analyzer using ``git merge-tree --write-tree --name-only``.
- Lists new upstream commits, classifies files into CONFLICTS /
LIKELY-MERGE / CLEAN before touching the working tree.
- For predicted-conflict files, prints a per-file resolution hint
(e.g. "anthropic_adapter.py: take ours for OAuth path; review
base-url + beta-gating areas").
- Verified against current upstream drift: correctly predicts 1
conflict (tools/skills_hub.py) for the 19 commits added since
yesterday's merge.
4. FORK.md
- Documents every fork-only file with rationale.
- Catalogs soft-fork edits with adds/dels per file.
- Explains "why a fork" + the never-upstream rule (per the
PR NousResearch#25234 lesson).
- Lists fork-only test files.
- Has a "when conflicts happen" runbook for the heavy-divergence
files (anthropic_adapter, conversation_loop, etc.).
Test results: 1469 / 1469 pass in tests/run_agent + tests/test_skill_recall_reminder.
End-to-end verified: AIAgent constructs cleanly, all 13 forwarders
accessible via MRO, all 10 fork state attributes initialized by their
respective init_state() calls.
Net divergence reduction vs upstream/main:
Before this commit:
run_agent.py +234 lines
agent/agent_init.py +122 lines
After this commit:
run_agent.py +179 lines (-55)
agent/agent_init.py +92 lines (-30)
Total: -85 lines of fork-specific code removed from upstream-merging files.

Got a second opinion (Fable) on the 2026-07-25 upstream-contribution- candidates audit, specifically stress-testing it against the PR NousResearch#25234 lesson: a self-audit written by the same context that produced a contaminated PR is not independent verification. Moved 5 items from Bucket A to Bucket B/likely-contaminated: - Claude Code Keychain write-back on OAuth refresh -- bugfix inside the CC-mimicry OAuth system itself, which is explicitly on the never-upstream list; upstream likely has no code path for this bug to exist in. - Bearer clients leak ANTHROPIC_API_KEY as x-api-key -- only portable if upstream's build_anthropic_client has the same bearer/API-key branching, which may only exist because of CC-mimicry OAuth support. - _sanitize_replay_block fail-closed -> fail-open -- FORK.md's own description admits it's tied to the fork's native-search feature while separately claiming to stand alone; that contradiction is the tell. - Background skill/memory review racing a live turn -- likely touches the same memory subsystem already flagged as needing de-forking elsewhere. - The "generalizable features" list (consult tool, tool_search deferral, trafilatura backend, hot-tier memory audit, delegate auto-route) -- already self-described as needing "light de-forking," which is the exact euphemism that hid 28K LOC in PR NousResearch#25234. Made explicit these are Bucket B, not batch-fileable with genuine bugfix PRs. Kept only the MCP orphaned-task asyncio bug in Bucket A as the highest-confidence genuine candidate, plus the general CLI/desktop bug list with per-item verification caveats added (confirm upstream has the same code path before trusting a fix is portable). Added a mandatory 4-step verification checklist (does upstream have this code path at all; diff against the real upstream file; grep for fork-only symbols leaking into the isolated diff; apply-test against a clean upstream clone) that every item must clear before filing, regardless of which bucket it's currently sorted into. No code changes -- FORK.md only. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
drop_orphan_server_tool_uses_in_storageonly scannedtool_search_tool_*_tool_resultblocks when deciding whichserver_tool_useblocks were paired.web_search_tool_resultwas invisible to it, so healthyweb_searchpairs got broken: the function dropped theserver_tool_usethinking it was unpaired, and every subsequent request 400'd on the now-orphanedweb_search_tool_result.web_search_tool_resultas a paired-result type AND drop orphans in BOTH directions (use without result, result without use). Apply the same symmetric drop to the outbound wire-build twin inconvert_messages_to_anthropicso a session that hits this state mid-turn still survives the next request.Repro / how this was found

That shape is unrealistic (Anthropic itself would 400 on it) and only passed because the old code was permissive in the wrong direction.
