Create build

POST /v1/tool/plugins/build

Builds and stores one plugin for the caller's org. The 201 carries the bundle's size, whether a model wrote the source, and the plugin as stored.

Post source to build TypeScript as-is, or spec — an OpenAPI document or plain prose describing the endpoints — to have one generated; the generated source comes back in the answer, so a caller reads what will run before it runs. Exactly one of the two, and name must be one lowercase path segment; both or neither is 400.

COMPILING IS THE GATE. The source goes through the same pipeline the committed connectors do — esbuild to one CommonJS program, then compiled in the goja runtime that will actually execute it — and anything that fails is rejected and NEVER stored. So a plugin in the store is one this deployment has already loaded once, not one a model claimed was fine. A failed build answers 422 carrying the diagnostics a caller needs to fix it: the bundler's error (detail), the source that failed, and whether the model wrote it.

CREDENTIALS ARE NOT PART OF A PLUGIN. A plugin names the connectors provider it needs and reads that credential from ctx.auth at run time, under KMS custody. Source that carries something key-shaped is REFUSED rather than silently persisted — a scrubbed key looks like it worked.

Request

4 fields, body application/json (required).

Response

201 body — 9 fields.

Failure carries the platform error shape — see Errors.
