Errors carried only a free-text
message+exitCode— nothing stable to search or link, and one site already hardcoded aDocs:URL inconsistently. This adds a central numeric error-code registry surfaced on all three error channels.What's new
@dawn-ai/sdk(errors.ts) — the leaf everyone depends on:DAWN_Exxxxcodes in ranges (E1xxx config · E2xxx sandbox · E3xxx permissions · E4xxx model/provider · E5xxx runtime/import), each{ code, title, docsPath? }. Codes are a literal union, so producers can't invent them.CliErrorgains an optionalcodeand the CLI prints[CODE] See <docs>; HTTP/SSE error bodies gaincode/docsUrl; permission denials returned as tool results are prefixed[DAWN_E3001].Docs:URL intool-discovery.tsis now centralized through the registry./docs/errorsreference page + a drift guard incheck-docs.mjs: everydocsPathmust resolve to a real page and/docs/errorsmust list exactly the registry's codes (negative-tested).Every message change is additive (an appended
[CODE]line or prefix), so no existing message assertion broke.docsPaths were reconciled to real pages —DAWN_E5001has no docs page yet, so itsdocsPathis omitted (a code without docs is valid).Full local verify green: build · typecheck (24/24) · lint (20/20) · test (1173 passed) · check-docs (+ new guard) · pack-check (8/8);
/docs/errorsrenders. Changeset: patch for@dawn-ai/{sdk,cli,core,sandbox,langchain}.Foundation for
dawn verify's preflight to emit codes (separate PR).🤖 Generated with Claude Code
