Release & changelog harness

Make releases understandable: every version bump has structured intent that agents and humans can read in git—not only in a maintainer’s head or a GitHub Releases textarea.

This skill is meta harness culture (which tool, which gates, which docs). It is not a full tutorial for every package manager. Follow work discipline. The former plugin-marketplace-setup skill was removed in 0.6.0.

Mixture of experts — critique your idea

Expert lens	Verdict on “use JS Changesets everywhere”
JS monorepo maintainer	Strong default: .changeset/*.md + changeset version beats hand-editing five package.json files.
Dart / Flutter publisher	Weak fit as-is: pub uses tags + CHANGELOG.md; monorepos often use Melos version / changelog, not npm Changesets.
Rust / Go shipper	Use release-plz, cargo-release, or git-cliff—forcing Changesets adds alien workflow.
Agent operator	Wins when notes live as small structured files in git agents can read and PR—not prose-only in Slack.
Multi-repo steward (~/mcp)	One legibility contract across siblings; different generators per ecosystem is fine.
Skill Steward charter	Teach when + gate + doc placement; link to upstream docs; do not paste 200-line configs into SKILL.md.

Improved framing (use this):

Adopt the release legibility contract first; pick the ecosystem-native generator second (Changesets is one excellent generator for JS workspaces, not the universal hammer).

See mixture-of-experts.md for extended debate and anti-patterns.

Release legibility contract (normative)

Before picking a tool, agree the repo obeys:

1. Notes in git — Changelog or changeset files are versioned; not release-notes-only in a web UI.
2. Structured contributor input — Contributors add intent in a fixed shape (e.g. .changeset/foo.md, conventional commit scope, or ADR note)—not “bump version when you remember.”
3. Mechanical publish path — One documented command sequence in DX_FAQ; CI is the source of truth for “can ship.”
4. Agent-readable output — Post-release, CHANGELOG.md (or per-package changelogs) reflects what shipped; agents can answer “what changed in vX?”
5. Why is recorded — Non-obvious toolchain choice → short ADR or DESIGN_FAQ Q&A.
6. Install trust matches release truth — The latest GitHub Release, release assets, checksums, package versions, and install docs must agree; stale pinned install examples are release drift.

Ecosystem router (default patterns)

Signal in repo	Default tooling	Notes
pnpm-workspace.yaml / npm workspaces	@changesets/cli	Industry standard for JS monorepos; pair with GitHub Action.
Single Node package, high release cadence	release-please or Changesets	release-please = conventional commits → PR; Changesets = explicit human/agent intent files.
Dart monorepo (melos.yaml)	Melos version + changelog	Align with pub publish order in DX_FAQ.
Single Dart package	CHANGELOG.md + git tag + dart pub publish	Keep entries agent-editable markdown.
Rust workspace	release-plz or cargo-release + git-cliff	Prefer automation that opens version PRs.
Product harness w/ binaries	release-please + tag CI + install.sh	Do not add a second version source; follow binary-release-contract.md
Meta + CLI binary (Skill Steward)	Changesets + single Release workflow + install.sh	Version PR updates git truth first; the release workflow tags, builds assets, creates/updates GitHub Release, and verifies latest/install trust per ADR 0014

Full matrix: ecosystem-tooling.md. Binary/install: binary-release-contract.md.

When to use this skill

• “We should use Changesets like the JS community”
• Release process is unclear, versions drift, or agents can’t tell what shipped
• Adding release CI, versioning policy, or monorepo publish workflow
• Auditing whether changelog tooling matches repo archetype (repo-quality-system-lifecycle)

Workflow

1. Classify the repo

Use repo-quality-system-lifecycle archetypes (app, library, CLI/tool, plugin, harness, meta/governance). Meta and harness repos need legibility; app repos need legibility and runtime compatibility notes.

2. Choose generator (ADR if non-obvious)

Question	If yes →
Multiple publishable JS packages?	Changesets (default)
Single package, commit-msg driven releases?	release-please
Maintainer writes explicit release notes per PR?	Changesets
Pub or Cargo primary?	Ecosystem table above—not Changesets

Record choice in docs/decisions/NNNN-release-changelog-tooling.md when more than one option is reasonable.

3. Wire harness surfaces

Surface	Action
DX_FAQ	Memory-palace block: add changeset, version, publish, verify tag
CI	Block publish/tag if changesets/changelog policy violated; for binaries, use one release owner or an explicit workflow_run/PAT handoff
AGENTS.md	One row in doc router—no full Changesets essay
CONTRIBUTING	“Every user-facing PR adds a changeset or CHANGELOG entry”

4. Minimal Changesets shape (JS monorepos and private packages)

Contributor adds:

---
"package-name": patch
---

Short imperative summary agents can quote in release notes.

Private Packages and Public Tags

By default, Changesets ignores packages marked with "private": true in package.json. To allow version bumps for a private root package or private workspace modules, update .changeset/config.json to include:

  "privatePackages": {
    "version": true,
    "tag": false
  }

Use "tag": false when a custom release script owns the public vX.Y.Z tag. Use "tag": true only when Changesets itself should create package-scoped tags.

Maintainer flow:

pnpm changeset          # or npx @changesets/cli
pnpm changeset version
pnpm install            # if lockfile must update
git commit -am "chore: version packages"

Publish: project-specific (changeset publish, GitHub Action, or npm provenance)—document exact commands in DX_FAQ, not here.

For automated Changesets releases, prefer:

merge feature PR with changeset
→ CI opens/updates Version PR
→ merge Version PR
→ same Release workflow creates vX.Y.Z, builds artifacts, creates/updates GitHub Release, verifies latest release state

If the tag is pushed with GITHUB_TOKEN, do not depend on a separate on: push: tags workflow to build assets; GitHub suppresses recursive workflow triggers for that token.

5. Choose distribution surface

Ship unit	Pattern
Executable MCP/CLI	GitHub Release binaries + checksums + install.sh — binary-release-contract.md
Skills only	npx skills add owner/repo — no repo tarball for consumers
Libraries	pub.dev / npm / crates.io per ecosystem table

Skill Steward: skills via npx skills; steward_cli precompiled AOT binaries via GitHub Releases & install.sh (ADR 0014).

6. Verify legibility

• Agent can read “what’s unreleased” from git without GitHub API
• CI fails when a version bump lacks notes
• DX_FAQ lists commands copy-paste ready
• No duplicate version sources (e.g. hand bump + bot bump)
• If binaries: tag assets match version SSOT; latest GitHub Release points to the package version; install.sh defaults to latest and pinned examples use placeholders or generated checks

Anti-patterns

Anti-pattern	Why it hurts
Changesets in a Rust-only repo	Wrong culture; contributors ignore it
Changelog only on GitHub Releases	Agents in repo context miss it
1,000-line release doc in AGENTS.md	Crowds task context; belongs in DX_FAQ / ADR
Skipping changesets “because AI will write CHANGELOG at release”	Non-deterministic; no PR-time review
Version bumps without consumer-facing sentence	Users and agents can’t assess upgrade risk
Binary Releases without changelog in git	Users see version; agents miss intent
Separate tag-triggered binary workflow after a GITHUB_TOKEN tag push	GitHub suppresses recursive workflow triggers; latest release/assets can silently lag
Static pinned install examples with real old versions	README/DX says one thing while GitHub Releases/install.sh say another
git clone as end-user install for a server product	Use install.sh + Release assets (binary release pattern)
