Build against it

# give your agent the catalog — no account, no install
claude mcp add provespec -- npx -y provespec-mcp

# then, from any agent session
spec_get(slug: "file-uploader-service")                → the capability tree
spec_checklist(slug: "file-uploader-service")          → the questions to answer
spec_grade(slug: "file-uploader-service", grades: [...])  → parity % + the gap list

# or just fetch it
curl https://provespec.com/catalog/file-uploader-service/spec.json

Grade every capability below as yes · partial · no · na, with a file reference as evidence. Whatever you leave ungraded counts as missing — the gap list is the work queue.

Or just paste this to your agent

Use the ProveSpec MCP server. Fetch the "file-uploader-service" spec with
spec_get, then walk spec_checklist and grade this repository against it —
one verdict per capability, each with a file reference as the note.
Call spec_grade with the results and give me the gap list as the plan.

If the server is not registered, add it first:
  claude mcp add provespec -- npx -y provespec-mcp
