Why

#177 landed inject into the selected agent. The follow-up is the rest of that workflow: local-only CLIs should look first-class, Custom should not require hunting through every downloaded weight, and renaming a bot should not require opening settings.

What

  • Add Qwen Code and Hermes Agent as Local agents. They have no subscription catalog; Custom is the product. Cloud agents stay in a Cloud group.
  • Custom still exists on every agent, including Claude, Codex, Grok, Kimi, Droid, OpenCode, and Antigravity.
  • Custom pins models the host already has in memory (oMLX /v1/models/status, Ollama /api/ps, LM Studio state=loaded) above a divider. Search filters the rest.
  • Install the CLI before Custom is pickable. A missing cloud login does not block inject.
  • Hermes inject writes providers.<host> and session/set_model custom:<host>:<model>. It does not set OPENAI_API_KEY, which was sending turns to OpenRouter (HTTP 401 Missing Authentication header).
  • Room turns pass each bot's picker model. Without that, Hermes hit OpenRouter 401, Qwen died with Internal error, and Grok silently used its cloud default.
  • Brand marks for the Local/Cloud rail. Double-click a bot name in the sidebar or chat header to rename it.
  • A small floating cursor above Automations turns into delete all bots? on click, so the sidebar does not need a trash icon.

Follow-up to #177. This does not cut a store release.

Tests

vitest run src/lib/custom-models.test.ts src/lib/engine-rail.test.ts src/lib/rename.test.ts src/components/EngineSetup.test.ts server/drivers/local-inject.test.ts server/drivers/local-inject-matrix.test.ts server/member-turn.test.ts server/config.test.ts server/harness/registry.test.ts

How to try

  1. Create a bot and open the picker.
  2. Cloud agents stay in the top group. Qwen and Hermes sit under Local.
  3. Open Custom. Anything already loaded is at the top; search finds the rest.
  4. Pick a live model from oMLX, Ollama, Unsloth, LM Studio, or EXO. That model is injected into the selected agent.
  5. Put Qwen, Hermes, and Grok in a room and ask who they are — all three should answer on the injected model.
  6. Double-click the bot name in the sidebar or the chat header to rename it.
  7. Click the floating cursor above Automations — it becomes delete all bots? Click again to confirm, Escape to cancel.

Local-only agents belong in a Local group next to Cloud, with the
same inject path as Claude, Codex, and Grok. Custom pins models the
host already has in memory, then the rest behind a divider, and the
list can be searched. Hermes injects through a named provider so it
does not fall through to OpenRouter. Double-click a bot name to
rename it without opening settings.

📝 Walkthrough

Walkthrough

The PR adds Qwen and Hermes engines, local model injection across multiple drivers, loaded-model discovery, access-aware engine selection, provider branding, and inline bot title editing.

Changes

Custom engine platform

Layer / File(s) Summary
Access metadata and default fleets
pnpm-workspace.yaml, server/contracts.ts, server/config.ts, server/harness/registry.ts, server/drivers/builtIn.ts, src/state/store.tsx
Engine metadata now includes access and loaded-model fields. Default fleets include Qwen and Hermes.
ACP driver model resolution
server/drivers/acp/core.ts, server/drivers/acp/{qwen,hermes,droid,kimi,opencode-go}.ts, server/drivers/antigravity.ts
Drivers resolve, persist, or translate local model identifiers before launch.
Local probing and validation
server/drivers/local-inject.ts, server/drivers/local-inject*.test.ts, server/testing/fake-acp-cli.ts
Local probing discovers catalogs and loaded models. Tests cover provider configuration, credentials, model translation, and environment handling.
Grouped engine and model selection
src/components/{ModelPicker,EnginesSettings,NoEngines,Onboarding,EngineSetup,ProviderIcons,EngineGroupLabel}.tsx, src/lib/{custom-models,engine-rail}.*
Engine views separate subscription and custom engines. The picker searches and pins loaded local models and uses provider marks and access-specific setup states.

Bot title editing

Layer / File(s) Summary
Rename behavior and editable title component
src/lib/rename.*, src/components/RenameTitle.tsx
Rename drafts are trimmed and validated. The component supports inline editing, commit, cancel, and focus behavior.
Chat and sidebar rename wiring
src/components/{ChatView,Sidebar}.tsx
Chat and sidebar titles dispatch updateBot after valid edits. Sidebar keyboard activation remains supported.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 84edf

Local-agent injection can corrupt shared CLI configuration during concurrent turns or select the wrong local model when distinct IDs collapse to the same alias, creating incorrect runtime behavior; merge should wait for fixes or explicit owner acceptance.

219-224: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Derive the loaded-probe URLs from host.baseUrl.

loadedProbeUrl hardcodes http://127.0.0.1:11434 and http://127.0.0.1:1234. LOCAL_HOSTS already declares those origins at Lines 21-24. If a host entry moves to another port, the catalog probe follows the new origin and the loaded probe silently keeps hitting the old one, so no row is pinned. Build the URL from host.baseUrl.

♻️ Proposed refactor
 function loadedProbeUrl(host: LocalHost): string | null {
-  if (host.id === "omlx") return `${anthropicBaseUrl(host)}/health`;
-  if (host.id === "ollama" || host.id === "local_ollama") return "http://127.0.0.1:11434/api/ps";
-  if (host.id === "lmstudio") return "http://127.0.0.1:1234/api/v0/models";

In `@server/drivers/acp/droid.ts`:
- Around line 100-102: Update the matching-model branch around match.id so that
when an ID is assigned to a customModels row, the updated settings are persisted
to settings.json before returning it. Add coverage for a matching customModels
entry without an id, verifying the generated ID is written and available to the
spawned CLI.

In `@server/drivers/acp/hermes.ts`:
- Around line 26-36: The upsertHermesProvider function must replace the complete
existing provider mapping, including nested YAML settings, rather than matching
only four-space property lines. Update hostRe to consume the provider block
through the next sibling provider key or otherwise parse the providers mapping,
while preserving unrelated providers and existing settings outside the targeted
hostId.

In `@server/drivers/acp/kimi.ts`:
- Around line 57-101: Serialize the shared configuration read-modify-write
operations so concurrent injections cannot lose entries or create duplicate
tables: in server/drivers/acp/kimi.ts:57-101, protect ensureKimiInjectAlias; in
server/drivers/acp/opencode-go.ts:134-143, protect the provider upsert; and in
server/drivers/acp/qwen.ts:60-70, protect the provider upsert. Use a shared lock
or equivalent atomic temporary-file-and-rename strategy for each CLI config
write.
- Around line 39-41: Extract a shared home-directory resolver that consistently
prefers HOME, then USERPROFILE, then homedir(), and use it in both kimiDataRoot
and credentialsPath. Preserve KIMI_CODE_HOME as the data-root override while
ensuring credentialsPath and the config root resolve to the same base home.

In `@server/drivers/acp/opencode-go.ts`:
- Around line 104-106: Guard the user-owned JSON parsing in the on-turn config
writers: in server/drivers/acp/opencode-go.ts lines 104-106, update the
opencode.json parsing near resolveTurnModel to retain the default config on
malformed input or rethrow with the file path; apply the same try/catch handling
to settings.json parsing in server/drivers/acp/qwen.ts lines 35-38, retaining an
empty settings object on failure.

In `@server/drivers/acp/qwen.ts`:
- Around line 45-46: Update the writeFileSync call that persists settings.env in
the Qwen configuration flow to pass mode 0o600, ensuring newly created settings
files are not group- or world-readable while preserving the existing content and
path.

In `@server/drivers/antigravity.ts`:
- Line 140: Update the catalog and selection flow around mergeLocalInject so
selectable local model IDs are routed through agy with the required oMLX host
configuration, ensuring IDs such as om​​lx::GLM-5.2-fp8 reach the local backend;
otherwise remove those local models from the catalog.

In `@server/drivers/local-inject.test.ts`:
- Around line 317-349: Move the KimiAgentDriver.create, DroidAgentDriver.create,
and AntigravityDriver.create calls into the existing try block so the finally
cleanup always restores globalThis.fetch when any creation rejects.

In `@server/drivers/local-inject.ts`:
- Around line 162-168: Update loadedIdsFromPayloads, specifically the add
helper, to store the matching catalog-form identifier when an endpoint id is
accepted via its base name; retain the full id as appropriate, ensuring
loaded.has(model) in probeLocalInjects recognizes catalog ids such as llama3.2
when the reported id is llama3.2:latest.

In `@src/components/Onboarding.tsx`:
- Around line 66-75: Update the unavailable custom-engine setup path in
EngineRow to pass intent="inject" to EngineSetup when instance.access is
"custom"; retain the default cloud intent for other engines.

In `@src/components/RenameTitle.tsx`:
- Around line 67-79: Update the rename trigger in RenameTitle to be
keyboard-focusable and handle Enter and Space key activation, invoking the same
draft initialization and setMode flow as onDoubleClick while preserving event
prevention and propagation behavior.
- Around line 50-55: Update the onKeyDown handler in RenameTitle so Enter does
not call finish(true) while event.nativeEvent.isComposing is true; retain the
existing preventDefault, stopPropagation, and finish behavior for non-composing
Enter events.

In `@src/components/Sidebar.tsx`:
- Around line 879-899: Update the sidebar row structure around the role="button"
container so RenameTitle remains outside the selectable control when renaming.
Move row selection, keyboard handling, context-menu behavior, and related
styling to a sibling control while preserving the existing bot selection
behavior; ensure RenameTitle remains independently exposed to assistive
technologies.

65-65: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use collision-resistant aliases for model IDs.

When model IDs differ only in slash placement, Line 65 generates the same alias. For example, foo/bar-baz and foo-bar/baz both become foo-bar-baz. The existing-table check then reuses the first model entry, so Kimi can launch the wrong model. Encode the model ID losslessly or append a stable hash. Verify that an existing alias maps to the requested inject.model before reusing it.

CodeRabbit: if a later driver create() rejects, the earlier instance
must already be in the array so finally can dispose it.
Clicking the same mascot as the bots turns it into "delete all bots?"
so the sidebar does not need a trash icon. Escape or a click outside
cancels. A second click after the morph confirms.
oMLX /health default_model is the configured default, not the models
in memory. Probe /v1/models/status and keep every loaded:true row
from every live host in one Custom list.
Compiled Qwen, Hermes, and the loaded-model probe so a checkout can
run the harness without a fresh server typecheck.
Ubuntu CI hit EACCES removing /tmp after SIGKILL; the tests themselves
passed. Retry the rm so a leftover lock does not fail the job.
Rooms used to call sendTurn without model. Hermes then skipped
session/set_model and hit OpenRouter (HTTP 401). Qwen spawned
without -m and died with Internal error. Grok silently used its
cloud default instead of the injected oMLX model.
Hermes, Qwen, and Grok all answer in the same room on the injected
oMLX model after room turns started passing the picker selection.

Closing as superseded. The useful work from this branch has already landed on main through the reviewed commit series (5669d58 through 9aa8039), with the related turn/workspace hardening now merged in #192. This preserves loaded-model search and pinning, room model/effort propagation, inline renaming, and the Qwen/Hermes/custom-engine improvements without reintroducing this branch’s outdated conflicts. Thanks @maxkongerskov — authorship remains preserved in the landed commits.
