Publish Reactor POST /tokens and keep command paths off the HTTP document by tombeckenham · Pull Request #648 · TanStack/schemas

tombeckenham · 2026-11-13T00:23:06Z

Summary

GET /v1/openapi/reactor now includes paths["/tokens"].post. The body is authorization_details (session scope, resources.models.match), the 200 body is jwt and expires_at (Unix seconds), and the operation requires the Reactor-API-Key header.
Model command schemas stay in components.schemas, tagged x-modelschemas-model and x-modelschemas-transport: realtime. They are not path operations. POST /reactor/{model}/events/{command} returns 404 on api.reactor.inc, so a generated HTTP client must not call them.
POST https://api.reactor.inc/tokens with no key returns 401.

Fixes #643

Test plan

Live: POST /tokens → 401, POST /reactor/fast-h3/events/move → 404

Summary by CodeRabbit

New Features
- Reactor’s API documentation now includes the POST /tokens endpoint, with its required API key and documented request and response details.
- Reactor model commands are identified as realtime capabilities rather than HTTP endpoints. Model-specific documentation includes the selected model’s schemas.
Documentation
- Updated the Quickstart and API descriptions to clarify the distinction between session-token HTTP requests and realtime model commands.

…ment. (#643) The generation document's only HTTP operation is POST /tokens. Model commands stay component schemas tagged x-modelschemas-transport: realtime, because those paths 404 on api.reactor.inc.

Walkthrough

Reactor’s generated OpenAPI document now exposes platform HTTP through POST /tokens, while model commands remain realtime component schemas. Provider configuration supports realtime commands and platform operations, including pinned-model filtering. Tests and documentation reflect this contract.

Changes: Reactor OpenAPI

Layer / File(s)	Summary
Token operation and provider contract `src/server/providers/types.ts`, `src/server/providers/adapters/reactor.ts`, `src/server/providers/adapters/reactor.test.ts`	Provider configuration now supports realtime commands and platform operations. The Reactor adapter defines `POST /tokens`, its request and response schemas, and the required `Reactor-API-Key` header. Tests check the operation and its model-pinned form.
Realtime OpenAPI generation `src/server/provider-openapi.ts`, `src/server/provider-openapi.worker.test.ts`	Realtime model schemas receive a transport annotation. Realtime documents use platform operations for HTTP paths and preserve model-owned schemas when a model is pinned. Tests check the paths, schemas, annotations, and pinned-model selection.
OpenAPI descriptions and Reactor notes `openapi.json`, `skill/modelschemas/SKILL.md`, `src/server/llms-txt.ts`, `src/server/openapi.ts`, `src/server/providers/adapters/hints.json`, `.changeset/reactor-tokens-realtime.md`	Descriptions and notes distinguish `POST /tokens` from realtime command paths. The quickstart retains the no-model-match error description, and the changeset records the OpenAPI change.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature · Severity of issue fixed: Medium

Merge Risk: Moderate · up to e95f7

Reactor's OpenAPI document will not expose POST /tokens whenever no command endpoints have been synced, which is the PR's stated goal. Build platform paths independently of stored command endpoints before merging.

Full details: Title check

Explanation

The title names the two main changes: publishing Reactor POST /tokens, and keeping command paths off the HTTP document. The changeset matches both. The summary shows the token operation added to the Reactor OpenAPI document and model commands kept as realtime component schemas rather than HTTP paths. The title is specific, but it is a long, two-part title, so it is slightly less concise than ideal.

Full details: Linked Issues check

Explanation

[#643] Requirement 1: add POST /tokens. The change set adds paths["/tokens"].post to the Reactor document (reactor.ts, provider-openapi.ts). The summary states the request body is authorization_details with type session and resources.models.match, the 200 response has jwt and expires_at, and the operation requires the Reactor-API-Key header. The test suite (reactor.test.ts, provider-openapi.worker.test.ts) asserts these fields, header, and operation ID.

[#643] Requirement 2: keep command schemas, but do not publish them as HTTP operations. The summary states that provider-openapi.ts replaces endpoint paths with platformOperations() for realtime providers (realtimeCommands === true). Command schemas stay in components.schemas with x-modelschemas-transport: realtime. The issue allows this option (components only, or a transport marker). The document therefore has no command path operations.

[#643] Acceptance: the only path operation is /tokens, which returns 401 without a key on api.reactor.inc, so it does not return 404. Command paths are absent, so no HTTP path returns 404. The PR description reports a live check for POST /reactor/fast-h3/events/move returning 404, but that path is no longer in the document.

The issue note that @tanstack/ai-reactor stays outside the generator is context, not a coding requirement of this PR. Evidence for this assessment comes from the PR summary and the test description; I did not re-read the full diff. packages/client/src/generated/sdk.gen.ts is in ignored_files and was not inspected. No requirement depends on it.

Full details: Out of Scope Changes check

Explanation

All changed files relate to the #643 objectives. Code changes: src/server/providers/adapters/reactor.ts (token schema and platform operations), src/server/providers/types.ts (realtimeCommands and platformOperations declarations), src/server/provider-openapi.ts (realtime path handling and transport annotation), and src/server/openapi.ts (description of Reactor HTTP surface). Tests: reactor.test.ts and provider-openapi.worker.test.ts cover the new behavior. Documentation: openapi.json description, skill/modelschemas/SKILL.md, src/server/llms-txt.ts, hints.json, and the changeset describe the new publication model and do not change package behavior. The summary shows no unrelated functional change. packages/client/src/generated/sdk.gen.ts is excluded by ignored_files and was not evaluated.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Use X2’s token scope in the pinned enum.

For ?model=x2, this line produces models.match with the sole permitted value x2. Reactor’s X2 API reference uses xmax/x2 for that token scope. A client generated from the pinned document cannot submit the documented X2 request. Align the catalog ID and token scope, or map the pinned ID to the token scope explicitly. (reactor.inc)

Major · Functional Correctness · Heavy lift

Publish platform operations when no command endpoints are selected.

The early return at lines 1228-1238 runs before the realtime branch at lines 1316-1317. When no command endpoints are synced, such as on a fresh installation before the first sync, selected is empty. The request then returns no_endpoints (404), or spec_requires_selector (400) when filtered by activity or model. platformOperations never runs, so GET /v1/openapi/reactor cannot return the POST /tokens operation in that state.

Platform paths do not depend on synced command endpoints. Build them independently of selected, and allow a document that contains only platform operations. Keep the existing connect check and the filtered error behavior for requests that cannot produce a useful document.
