What it does

Eng Contract Codegen Coship is an agent skill from compozy/compozy. Contract co-ship for Compozy 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.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/coship-checklist.md`).

It sits in Backend & APIs, covering Project scaffolding, OpenAPI specifications and Refactoring. It works with OpenAPI. The repository describes itself as: An operating system for AI agents. Plug in the agent CLIs you already use (Claude Code, Codex, Gemini CLI, Cursor) and they become a team: they split the work, hand tasks to each… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit eec2ed1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Eng Contract Codegen Coship loads about 664 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 73 tokens; SKILL.md has 305 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~664
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Contract Codegen Co-Ship

Ship changed wire contracts with their generated artifacts and affected consumers. Triggers include public DTOs under internal/api/contract/ or internal/api/spec/, OpenAPI/generated clients, JSON-RPC extension shapes, and handler request/response/status/authentication/error semantics.

  1. Identify the owning contract and compatibility regime. Preserve SD-013: public replacements auto-migrate losslessly where possible; otherwise retain the old shape for one release with warnings and a named removal release. Only documented experimental surfaces may skip that window. Internal consumers change together.
  2. Use applicable sections of references/coship-checklist.md to trace consumers. Record impact once in the owning spec/task/PR using docs/_memory/change-impact.md; reuse existing decisions and group unaffected surfaces instead of producing a no-impact form per item.
  3. Run root make codegen after changing the owning source. It also owns JSON-RPC Go-to-TypeScript generation. Inspect generated output and co-ship it with source; investigate unrelated drift or nondeterminism.
  4. Update affected Web types, adapters, query keys/options, hooks, components, MSW fixtures, and stories. Import generated DTOs rather than maintaining copies. Read only the layers the changed shape reaches.
  5. Update applicable site/protocol/config documentation and run make cli-docs for CLI changes. Document active migrations and deprecations; remove old public docs only when the corresponding surface is eligible for removal under SD-013.
  6. Verify no generator drift with make codegen-check and use the affected root Turbo lint/typecheck/test/build lanes for Web/site changes. Reuse checks already covered by the root gate. Commit/push and PR completion follow root make gate/CI policy once at their delivery stage.

Complete when source, generated output, affected consumers, fixtures, docs, and required delivery evidence agree. A local task does not acquire a PR-publication requirement merely by loading this skill.

If a consumer typecheck fails, diagnose the actual mismatch; it does not automatically prove a mirrored DTO. For runner-only failures, inspect the failing CI lane and reproduce the relevant environment rather than assuming every failure is Linux race parity.
