# V2 HTTP API audit checklist

**Source:** `packages/protocol/openapi.json`  
**Current endpoint count:** 139
**Last regenerated:** 2026-09-13

## How to use this checklist

Review endpoints in document order. For each endpoint, select one disposition and capture rationale or follow-up work in Notes. Mark **Reviewed** only after the disposition is agreed.

### Review criteria

- Resource and operation naming
- HTTP method and idempotency
- Request parameters and location scope
- Response shape and error taxonomy
- Authentication and authorization
- Current production consumers
- Stability level: public, experimental, or internal
- Whether the generated client API is intuitive

### Disposition legend

- **Keep:** ship unchanged as a supported V2 API
- **Change:** retain after a defined contract change
- **Remove:** exclude from the official V2 API
- **Experimental-only:** retain outside the stable API commitment

## Resolved during audit

### [x] `POST /api/plugin/await-activation`

- **Decision:** Remove
- **Notes:** Activation timing is an internal server concern. Catalog reads remain non-blocking.

### [x] Location response wrappers

- **Decision:** Reduce generic endpoint response locations to `{ directory }`.
- **Notes:** Full project metadata remains available from `GET /api/location`; no consumers used it from wrapped responses.

### [x] `GET /api/health` and `GET /api/server`

- **Decision:** Merge and rename
- **Replacement:** `GET /api/status` with operation ID `server.status`.
- **Notes:** Returns `version`, `pid`, and connection `urls`; readiness is conveyed by HTTP status.

### [x] `GET /api/project/current`

- **Decision:** Remove
- **Replacement:** `GET /api/location`, using `project` from the response.
- **Notes:** The endpoint duplicated `Location.Info.project`; production callers were migrated.

### [x] `POST /api/workspace` and `DELETE /api/workspace/{workspaceID}`

- **Decision:** Remove
- **Notes:** Provider-backed workspaces are not part of the V2 HTTP contract and can be introduced later. Core and the embedded SDK retain internal workspace support.
