perf(prompt-caching): cache tool schemas on native Anthropic without history loss by kshitijk4poor · Pull Request #76032 · NousResearch/hermes-agent

kshitijk4poor · 2026-08-01T08:48:14Z

Summary

On tool-heavy agents the ~12K-token tool schema was re-sent uncached on every internal LLM call — ~70% of input spend (issue #20880 measured $0.45 for 3 short turns). This salvages #37611 by @rodboev onto current main: on direct native Anthropic (api.anthropic.com + anthropic_messages) the 4-breakpoint cache budget is re-planned as static-system-prefix + tools[-1] + last-2 completed-transaction endpoints, making the tool schema a cached prefix. Every other route (OpenRouter, third-party Anthropic-wire gateways, chat_completions) keeps today's message-only layout byte-for-byte.

Closes #20880. Based on #37611 by @rodboev — commit cherry-picked with authorship preserved. The adapter wire plumbing for tool cache_control already exists on main (#23828, anthropic_adapter.py:1768); this PR is its first in-tree emitter.

Changes

agent/prompt_caching.py: build_prompt_cache_plan (request-local PromptCachePlan), strip_anthropic_tool_cache_control, _completed_transaction_endpoint_indexes (only completed tool runs / legal turn ends become endpoints; dangling tool_calls excluded; _can_carry_marker filtering retained)
agent/conversation_loop.py: initial plan + retry-loop redecoration now plan messages AND tools; canonical agent.tools never mutated
agent/chat_completion_helpers.py / run_agent.py: build_api_kwargs(..., tools_for_api=) request-local tools override
agent/agent_runtime_helpers.py: _direct_native_anthropic_tool_cache_capability — tool markers gated to api.anthropic.com + anthropic_messages only
agent/auxiliary_client.py: sync fallback destinations replan both sections locally; configured fallback entries preserve resolved provider/base_url/api_mode/model
agent/moa_loop.py: prepared MoA aggregator plans its resolved destination locally without decorating prepared state
6 test files: 8 new tests incl. the Tool-heavy agents pay ~70% input-token overhead — system_and_3 caching skips tools schema #20880 tool-heavy-loop behavior contract

Note: open PR #27170 takes the opposite approach (strips tool markers + budget sanitizer); its premise is superseded by this planner and it should be closed if this merges.

…ch#20880)

…atile suffix _apply_static_prefix_marker duplicated _apply_system_cache_markers' split logic minus its empty-suffix guard: when the stored system prompt equals the static prefix exactly, the tool-cache plan emitted a two-part split with a trailing empty text block — HTTP 400 on native Anthropic. Fold the tool-cache layout into the existing helper via mark_suffix / fallback_to_whole flags; the empty-suffix case now marks the prompt as one whole block. Behavior-parity verified against the merged planner for every non-empty-suffix shape. Follow-up to #76032 (#20880).

…abel parsing Three copies of the same logic landed with #76032: - MoA's _call_prepared_aggregator and auxiliary_client's _replan_synchronous_cache_sections both implemented stub → policy → strip → plan for a resolved destination. Extract plan_cache_sections_for_destination() into agent_runtime_helpers (which already owns the policy functions) and route both through it. Also removes a redundant full-transcript deepcopy+strip per request (the caller pre-stripped what build_prompt_cache_plan strips again). - The fallback_chain[N] label regex + chain-entry lookup lived in _fallback_entry_timeout AND _fallback_destination. Extract _fallback_chain_entry() and reuse. MoA's cache-plan failure log is promoted debug → warning: the call-block site skips MoA, so this block is the aggregator's only decoration path — a silent failure ships an undecorated request (the 0%-cache MoA bug class). Behavior-preserving; 195 targeted tests green. Follow-up to #76032 (#20880).

The count walked every message part and tool schema on every request but is consumed only by tests. Compute it on demand via a property instead. Follow-up to #76032 (#20880).

_call_fallback_candidate_sync replans messages/tools for each resolved destination, but its async mirror still shipped the caller's decorated sections verbatim — the primary destination's markers (including a direct-native tool marker) leaked to fallback candidates with different cache contracts, and the relay saw the display label instead of the resolved provider/api_mode. Mirror the sync path: resolve the destination, replan both sections, thread provider/api_mode through _relay_async_completion, and replan again for the auth-refresh retry client. Mutation-checked: the new parity test fails on the verbatim pass-through shape. Follow-up to #76032 (#20880).

Around that spine: the desktop app became a platform (artifacts with live preview, a plugin SDK, quick-entry from anywhere, multiple windows), the CLI got a wave of power commands (`!` shell mode, `/init`, `/diff`, `/context`, `/focus`), compression got smarter and gentler, and the tools themselves now recover from their own failures instead of making the model guess. This release rolls up everything from the v0.19.1 infrastructure patch tag — that window is fully documented here. *** ##### ✨ Highlights - **Talk to Hermes — streaming, conversational voice with barge-in** — Voice mode used to mean: speak, wait for the whole reply to generate, then listen to one long audio file. Now Hermes speaks clause-by-clause as the response streams, you can interrupt it mid-sentence by just talking (it stops, listens, and the model is told you cut in), and busy-aware silence detection means it doesn't talk over you. This works in CLI voice mode, on the desktop, and through gateway adapters. Talking to Hermes finally feels like a conversation, not a voicemail exchange.

Multi-profile voice routing means different wake words can reach different profiles, and saying "stop" ends the voice chat on every surface without touching the keyboard. Your terminal is now something you can talk to from across the room.

A real **plugin SDK** landed with Kanban as its founding plugin, `ctx.download` for handing users files, floating pane placement, and multiple GUI windows. A global-hotkey **quick-entry window** captures a thought into any session from anywhere in your OS. The desktop stopped being a chat client and started being a workbench.

…atile suffix _apply_static_prefix_marker duplicated _apply_system_cache_markers' split logic minus its empty-suffix guard: when the stored system prompt equals the static prefix exactly, the tool-cache plan emitted a two-part split with a trailing empty text block — HTTP 400 on native Anthropic. Fold the tool-cache layout into the existing helper via mark_suffix / fallback_to_whole flags; the empty-suffix case now marks the prompt as one whole block. Behavior-parity verified against the merged planner for every non-empty-suffix shape. Follow-up to NousResearch#76032 (NousResearch#20880).

…abel parsing Three copies of the same logic landed with NousResearch#76032: - MoA's _call_prepared_aggregator and auxiliary_client's _replan_synchronous_cache_sections both implemented stub → policy → strip → plan for a resolved destination. Extract plan_cache_sections_for_destination() into agent_runtime_helpers (which already owns the policy functions) and route both through it. Also removes a redundant full-transcript deepcopy+strip per request (the caller pre-stripped what build_prompt_cache_plan strips again). - The fallback_chain[N] label regex + chain-entry lookup lived in _fallback_entry_timeout AND _fallback_destination. Extract _fallback_chain_entry() and reuse. MoA's cache-plan failure log is promoted debug → warning: the call-block site skips MoA, so this block is the aggregator's only decoration path — a silent failure ships an undecorated request (the 0%-cache MoA bug class). Behavior-preserving; 195 targeted tests green. Follow-up to NousResearch#76032 (NousResearch#20880).

The count walked every message part and tool schema on every request but is consumed only by tests. Compute it on demand via a property instead. Follow-up to NousResearch#76032 (NousResearch#20880).

_call_fallback_candidate_sync replans messages/tools for each resolved destination, but its async mirror still shipped the caller's decorated sections verbatim — the primary destination's markers (including a direct-native tool marker) leaked to fallback candidates with different cache contracts, and the relay saw the display label instead of the resolved provider/api_mode. Mirror the sync path: resolve the destination, replan both sections, thread provider/api_mode through _relay_async_completion, and replan again for the auth-refresh retry client. Mutation-checked: the new parity test fails on the verbatim pass-through shape. Follow-up to NousResearch#76032 (NousResearch#20880).
