Thread titles, commit and PR text, branch names, and transcript cleanup could only run through a coding agent, which starts a full agent session per request. https://git.cafe/pingdotgg/t3code/pulls/33007 added direct model APIs, but only for voice cleanup, as a separate set of voice-only settings. This makes text generators a core concept that every text generation task can use.

How it works

• Settings. A new textGenerators setting holds model APIs that only generate text. It supports two kinds: OpenAI-compatible (presets for OpenAI and OpenRouter, plus a custom endpoint for Ollama, LM Studio and similar servers) and Anthropic. The API key is a normal secret setting, so it can reference a secret provider and is redacted for clients.
• Routing. A text generator's id fills a model selection's instanceId, so the existing text generation, source control writer, and transcript cleanup selections can each pick one with no new fields. TextGeneration sends those selections to the API through the same Runner and fromRunner path that provider text generation already uses.
• Not a provider. Text generators are not provider instances. They never show up on agent surfaces such as the composer, thread launch or MCP; the pickers only see them through a client-side adapter in the three text generation settings panels.
• Model discovery. A new server.listTextGeneratorModels RPC fetches the model list on first use. The server keeps it until the generator's config changes or someone presses refresh. Anthropic responses are paginated.
• Limits.
  • Review guides need an agent that can read the checkout. When a review guide would reach a text generator, including through the source control writer fallback, it falls back to Codex or Claude. If neither is ready, it fails with a message saying so instead of a missing-provider error.
  • A managed provider allow-list turns text generators off.
• Settings UI. Settings → Providers gets a Text generators section next to Usage providers, where you add, edit, enable, refresh and remove them. It is hidden under a provider allow-list. In model pickers, each generator shows the service it reaches, read from its URL: OpenAI, Anthropic, OpenRouter, Ollama, or a server glyph for other endpoints. Two generators get an instance badge only when they reach the same service.

Verification

• vp run check:changed passes. New tests cover:
  • Both drivers' request and response handling, and the error text for HTTP failures.
  • Model list caching and Anthropic pagination.
  • The shared model resolvers.
  • Secret redaction round-trips for older clients.
  • The review-guide fallback; this test fails without the fix.
• Tested in a dev build:
  • Added a custom OpenAI-compatible generator pointed at a CLIProxyAPI hub and picked claude-haiku-5-5 from its 115 discovered models.
  • Started a thread from the composer; the server wrote the title "Settings Page Unset Timezone Crash" with one 2.5 s API call and no agent session.
  • The composer picker does not list the text generator. The source control writer picker does.
• Checked the Anthropic request shape against the same hub: /v1/messages and paginated /v1/models.

Settings → Providers	Text generation model picker

Left out

• Reasoning effort. There is no reasoning-effort control for API models yet; pick a fast model.
• OpenCode raw generation. https://git.cafe/pingdotgg/t3code/pulls/33007 also used OpenCode's raw /generate/text endpoint. That change speeds up OpenCode's own runner for every task, not just cleanup, so it belongs in its own PR.
• Mobile. Mobile has no text generation model pickers, so it needs no change.

Supersedes #33007.

Implemented with Claude Opus 5.5 in Claude Code, driven from T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Adds opt-in model APIs for titles, source-control writing, and transcript cleanup, with secret handling and managed-provider restrictions. An open review concern needs resolution: shared model selections can reach environments whose API keys lack access to that model.

Walkthrough

This change adds text-generator settings and selection rules, server drivers and model-list RPC support, and web settings for managing and using text generators. It also updates secret handling, managed-provider limits, tests, and documentation.

Changes: Text generator support

Layer / File(s)	Summary
Settings and selection rules packages/contracts/src/settings.ts, packages/shared/src/serverSettings.ts, packages/shared/src/projectSettings.ts, apps/server/src/policy/managedProviders.ts	Server settings and patches include text generators. Selection resolution accounts for generator enablement and usability. Managed-provider limits can clear text generators.
Server drivers and generation execution apps/server/src/textGeneration/*	OpenAI-compatible and Anthropic drivers send generation and model-list requests. The TextGenerators service resolves configuration and secrets, caches model lists, and supplies runners. TextGeneration routes eligible operations through runners and treats review guides differently for text generators.
Model-list RPC wiring packages/contracts/src/rpc.ts, packages/contracts/src/clientRpcPermissions.ts, packages/client-runtime/src/state/server.ts, apps/server/src/ws.ts, apps/server/src/observability/RpcInstrumentation.ts	The model-list RPC is defined, guarded by settings-write authorization, and connected through the client runtime and server WebSocket handler.
Web settings and model targets apps/web/src/textGenerators.ts, apps/web/src/components/settings/*, apps/web/src/components/chat/ProviderInstanceIcon.tsx, apps/web/src/components/Icons.tsx	The web app adds generator presets, model discovery and refresh, environment-scoped generator controls, and text-generator targets for settings pickers. Provider icons and settings search support the new settings.
Secret references and documentation apps/server/src/settingsSecrets.ts, apps/server/src/sourceControl/sourceControlHostSecrets.ts, apps/web/src/components/settings/SecretsSettings.logic.ts, apps/server/src/serverSettings.test.ts, docs/*	Server secret mapping and invalidation include generator API keys. Web settings identify generator secret use. Tests cover redaction and secret-reference round trips. Documentation describes text-generator setup and use.

Full details: Title check

Explanation

The title names the main change: text generators, which are model APIs that can write thread titles, commit text, and transcript cleanup. The changeset adds a textGenerators setting, routing through the existing text generation runner, a listTextGeneratorModels RPC, and a settings UI, all of which match the title. The title uses the conventional feat: prefix and is 82 characters, slightly over the usual length but still readable.

Full details: Description check

Explanation

The description follows the template sections (Problem, Change, Scope and approval, Verification) only loosely. It explains the problem (text generation only worked through coding agents, and the prior voice-only path was limited) and the change in detail, and it gives substantial verification notes with manual steps, tests, and screenshots. However, it has no explicit Scope and approval section: it does not link a triaged issue or maintainer approval for the feature, and it only references superseding PR #33007. The template also says adding a setting alone is not an approval exemption, and this PR adds a new capability, so approval is missing. The description also omits the template's required agent/model note at the end, though it does include 'Implemented with Claude Opus 5.5 in Claude Code', which partially covers it. Verification is concrete rather than 'tests pass' alone.

Resolution

Add a '## Scope and approval' section that links the triaged issue or the discussion with explicit maintainer approval of this direction, including the approval comment. The PR is a broad new feature (new setting type, RPC, settings UI, and routing changes), so it needs that approval. Also restructure the description under the template headings (Problem, Change, Scope and approval, Verification), and keep the agent/model line at the end. Optionally, add a Problem section that states expected behavior and reproduction steps in one or two sentences, separate from the How it works list.

Minor · Functional Correctness · Quick win

The primary button is outside the <form>, so the dialog has no implicit submit.

The form has an onSubmit handler but no submit button inside it. Pressing Enter in a single-line input does not submit a form that has more than one text field and no submit button. The user must click Add or Save. Move the primary button into the form with type="submit" and the form attribute. Alternatively, set form="text-generator-form" on the button and add that id to the form.

Major · Functional Correctness · Heavy lift

Do not use the generator brand to prove model availability.

If two environments configure the same custom generator ID with different API endpoints, both entries can have the openaiCompatible brand but different model lists. This check permits a model from the shown environment to be saved for both. Text generation can then fail in the other environment. Check the target model list before allowing a shared selection, or require the user to select each environment separately when availability is unknown. (raw.githubusercontent.com)

As per coding guidelines, “Multi-device and multi-environment cases are real.”

Fixed in 9e50bb4: a shared selection now requires each environment's generator to have the same kind and base URL as the shown one, not just the same brand. A different endpoint asks the user to pick that environment separately.

[coderabbitai]

@juliusmarminge Thanks for fixing the different-endpoint case. Matching the kind and base URL still does not verify model availability: API keys for the same endpoint can have different model access.

Could you check the target generator’s model list, or require a separate selection when its availability is unknown?

Source excerpt:
# Architecture

## Settings ownership

Client preferences stay in the current client; environment defaults and project overrides stay
on their owning server. The web and desktop settings target is URL state, resolved against current
connections and project membership. An unavailable target must not fall back to another environment.
**All environments** is an explicit bulk edit of connected, loaded servers, not a durable global
default or a promise to synchronize offline or future environments. Project-group targets similarly
select known environment-local checkouts; the group itself does not store inherited defaults.

_{You are interacting with an AI system.}

[juliusmarminge]

Leaving this as is: only the shown environment's model list is loaded, and loading every target's list to vet a shared pick is more machinery than the case warrants. Same endpoint with a key that lacks the model fails at generation time with the API's own error, and the per-model Test button surfaces it up front.

[coderabbitai]

@juliusmarminge Understood. Matching the kind and base URL addresses the different-endpoint case. I accept the decision to leave key-specific model access unverified and rely on the Test button or generation errors.
