release

name: release description: >- Cut a software release and maintain a tiered compatibility policy. Use when the user wants to release, ship a version, bump the version, tag a release, write a changelog, or update COMPATIBILITY. Config-driven via release.config.json; bumps version files, runs a readiness gate, updates COMPATIBILITY.md tiers and deprecations, tags (→ release workflow), and reports closed issues. Teaches the underlying standards as it runs.

release — tiered compatibility & release workflow

A config-driven release orchestrator. Mechanics live in scripts/release.py (unit-tested, stdlib-only); this file is the workflow you (or an agent) follow. Read reference/config-schema.md for release.config.json and reference/standards.md for why each step exists.

Scope honesty: reference-tested on a Tauri + Rust + SvelteKit repo (Cull). Other stacks are supported by config, not yet validated. Treat first runs on a new stack as a dry run (see "Dry run" below) until you trust it.

When to use

The user says "release", "ship it", "cut a version", "bump version", "tag a release", "update the changelog/COMPATIBILITY". Requires a release.config.json at the repo root (scaffold from templates/release.config.json.tmpl).

Mental model — your public API is your declared surfaces

A version only means something once you declare what you promise to keep working. release.config.json → surfaces[] is that declaration; each surface has a tier (experimental → preview → stable) and a compatibility mode. Only stable surfaces carry the promise. Breaking a stable surface forces a major bump — the engine enforces this. (Standards: see reference/standards.md.)

Command

/release <patch|minor|major> — run the steps below. On an unfamiliar repo, do a dry run first (see below). When the user asks to "explain", expand each step's why into a short lesson from reference/standards.md.

Steps

1. Preconditions. The configured releaseBranch (default main, in worktree if set) is checked out, clean, and synced with origin. Abort clearly otherwise. — why: a release tag must point at a known-good, pushed tree.

2. Version. python3 scripts/release.py --config <cfg> plan <kind> prints the new version + tag. It asserts the version files currently agree. Show old → new. — why: SemVer math; 0.x lets minors break (pre-1.0). [[Semantic Versioning (SemVer)]]

3. Readiness gate. Run cfg.gate then each cfg.extraGate[]. All must exit 0 (fmt, clippy, tests, license audit, prod build, golden contract tests). Block on failure. — why: this is a Production-Readiness Review. [[Production Readiness Review]]

   • TODO (deferred): cargo-deny / cargo-audit / SBOM. List, don't enforce yet.

4. Changelog. Collect commit subjects since the last tag (git log <lastTag>..HEAD --format=%s) and draft a section — the engine's draft_changelog buckets them into Added/Changed/Fixed (Keep a Changelog). Insert under the top of CHANGELOG.md; hand-curate the user-facing lines. — why: humans read changelogs; conventional commits seed them. [[Keep a Changelog]]

5. Compatibility review. Open cfg.compatibility.path (COMPATIBILITY.md). Ask:

   • Did any surface change tier? (update the Surfaces table)
   • New deprecations? (add a row: item / deprecated-in / removable-in / replacement)
   • Does this change break a stable surface? If yes, the required bump is major — re-run with major or the release is invalid. (Enforced by enforce_bump.) Stamp "Last updated: ()". — why: tiers + deprecation windows are how you evolve without lying. [[Kubernetes API Deprecation Policy]]

6. Bump & commit. python3 scripts/release.py --config <cfg> bump <kind> writes every version file; refresh cfg.lockfiles (e.g. cargo update -p <crate> or a build). Commit chore(release): v<new> including CHANGELOG + COMPATIBILITY.

7. Tag & push. git tag v<new> and push the tag (→ the repo's release workflow) and the branch. Confirm the tag trigger exists before the first release (grep -A3 '^on:' .github/workflows/*.yml).

8. Report. Print the tag, the release-workflow URL, and issues closed since the last tag (if cfg.issueTracker is set, e.g. bd) — those are the release notes.

Dry run

There is no --dry-run flag — a dry run is steps 1–5 done without mutating: run python3 scripts/release.py --config <cfg> plan <kind> (pure: prints the version/tag, writes nothing) and optionally run cfg.gate to check readiness. Do NOT run bump, commit, or tag. The bump subcommand is the only engine command that writes (version files only); commit/tag/push are git steps you take in step 6–7, never the engine.

Manual fallback (no skill)

plan → run gate → edit CHANGELOG + COMPATIBILITY → bump → commit → tag → push. The engine is just scripts/release.py; everything else is git.

Growing into Contracts & Modes

The readiness gate runs golden/contract tests (cfg.extraGate). Start with one (a DB round-trip), then add export and API contract tests. See the consuming repo's docs/CONTRACTS.md and reference/standards.md. [[Pact — Consumer-Driven Contract Testing]]
