Contract co-ship for AGH wire changes. Use when editing public DTOs, OpenAPI, JSON-RPC extension shapes, generated clients, or handler request/response semantics. Do not use for internal Go refactors or test-only changes that leave the wire contract unchanged.

Contract Codegen Co-Ship
Ship one atomic wire-contract bundle. This file owns the sequence;
references/coship-checklist.md owns the inventory.
Procedures
Step 1: Detect the Trigger
Inspect the staged or about-to-be-edited files. Triggers (any one match):
internal/api/contract/**.go
internal/api/spec/**.go
openapi/agh.json
openapi/compozy-daemon.json
web/src/generated/**
a public handler's request, response, status, authentication, or error shape changes even before a contract file is edited
If no path or semantic trigger fires, this skill does not apply.
Done when: every changed wire shape and owning source is named, or the skill is explicitly ruled out with evidence.
Step 2: Plan the Co-Ship Bundle
Read .agents/skills/agh/agh-contract-codegen-coship/references/coship-checklist.md in full.
Mark every applicable source, generated, backend, Web, site, CLI, UDS, native-tool, extension, config, QA, and official-skill item before editing.
Record explicit no-impact evidence for checklist branches that do not apply.
Done when: every applicable checklist item has one owning file or verification command and no public surface is left implicit.
Step 3: Run Codegen Locally
Execute make codegen from the repo root. This regenerates openapi/agh.json and web/src/generated/agh-openapi.d.ts.
If the contract is a JSON-RPC extension shape (not REST), the Go→TS generator also runs through make codegen (see internal/codegen/openapits/generate.go).
Inspect the generated diff. Generated files MUST commit alongside source.
Done when: generated artifacts are deterministic, reviewed, and synchronized with their owning source.
Step 4: Update Web Consumers
For each affected web/src/systems/<system>/:
Open types.ts. Remove DTOs that simply mirror the regenerated TypeScript types — import from @/generated/agh-openapi or the local re-export instead.
Open adapters/. Update the typed wrappers if the request/response shape changed.
Open query-keys.ts and query-options.ts if response shape affects keys.
Open hooks/. Update query/mutation hook return types and rollback logic.
Open components/. Update presentational props if exposed shape changed.
Update MSW fixtures and Storybook stories to match the new contract.
Done when: every affected consumer imports the canonical generated shape and its runtime/test fixtures agree.
Step 5: Update Site Documentation
CLI verb changes: regenerate make cli-docs so packages/site/content/runtime/cli/ reflects the new flags / commands.
HTTP endpoint changes: update packages/site/content/runtime/<area>/ MDX files and any protocol documentation.
Removed CLI verbs / endpoints / config keys: delete the doc pages in the same change (no "deprecated" markers).
Done when: public docs and agent-manageable surfaces describe only the shipped hard-cut contract.
Step 6: Verify the Bundle
Run make codegen-check. Output MUST be clean (no drift).
Run make bun-lint from the repository root.
Run bunx turbo run typecheck test build --filter=./web from the repository root when Web consumers are affected.
Run bunx turbo run typecheck test build --filter=./packages/site from the repository root when site content or generated inputs are affected.
Confirm every applicable co-ship checklist item passes.
Reserve the single full make verify for the completion gate after source freeze.
Done when: codegen has no drift, affected Turbo lanes are green, the checklist is complete, and exactly one fresh full monorepo gate is scheduled or complete for the finished task.
Error Handling
make codegen shows large diffs unrelated to your change: something else is out-of-date in the source tree. Investigate before committing — generated drift hides regressions.
make codegen-check fails after make codegen: there's a non-deterministic generator. Inspect the generator's output ordering, file formatting, JSON normalization. Use semantic JSON comparison and run formatter before write/check (lesson docs/_memory/analysis/analysis_local_runs.md issue #6).
Web typecheck fails on imported generated type: the consumer is mirroring instead of importing. Move it to use the generated type and delete the duplicate.
packages/site build breaks because a documented page references a removed verb: delete the page; don't add a "see new verb" stub.
CI passes locally but fails on a runner: Linux-race CI parity issue. Reproduce with act workflow_dispatch -W .github/workflows/ci.yml -j verify --container-architecture linux/amd64.
