name: release-prep description: > Release readiness: changelog generation, semver-checks, version bump suggestion, doc verification, multi-crate ordering. Use when preparing a crate or project for release. disable-model-invocation: true argument-hint: "[crate or version]"

Purpose

Prepare a crate or project for release with a structured checklist: generate a changelog, detect breaking API changes, suggest the correct version bump, verify documentation is current, and handle multi-crate workspace release ordering.

This is an interactive skill. Present each release decision (version bump, changelog entries, documentation gaps) for user approval before acting.

Instructions

0. Context recall (SeleneDB)

If SeleneDB is available (see selene-integration.md), create a session and recall prior release context:

Create session with skill: 'release-prep' and scope: $ARGUMENTS
Scoped auto-recall — query for prior releases:
- Prior :Release nodes for this project, ordered by date
- Any breaking changes from past releases
- Any :DeferredItem nodes gated on "next release"
If release history exists, present it:

"Prior release context:

Last release: v[version] on [date] ([bump type])

[N] breaking changes in last [N] releases

[Any deferred items gated on this release]

Proceeding with release scope analysis."

If no prior context exists, skip silently.

1. Determine scope

From $ARGUMENTS:

Single crate release or workspace-wide?
What was the last released version? (git tag --list 'v*' --sort=-v:refname | head -5)
What has changed since then? (git log --oneline <last-tag>..HEAD)

2. Detect breaking changes

Rust:

cargo semver-checks check-release -p <crate>

If cargo-semver-checks is not available, manually check:

Removed or renamed public items
Changed function signatures (parameters, return types, generics)
Changed trait bounds on public generics
Removed trait implementations
Changed default values or behavior

Python:

No automated semver-checker; manually review public API changes
Check __all__ exports, function signatures, class interfaces
Check pyproject.toml version and classifiers
Run pip-audit for security advisories before release

JavaScript/TypeScript:

Review exported types and function signatures
Check package.json version, exports field, types field
Run npm audit for security advisories
If TypeScript: check .d.ts files for breaking type changes

3. Suggest version bump

Based on the changes since last release:

Present the version bump as a decision with options:

"Based on the changes since [last version], I recommend a [bump type] bump to v[new version]. Here is why:

[Recommended bump] - [rationale]

[Alternative bump] - [when this would be appropriate instead]

Which version?"

Wait for the user to confirm before proceeding.

Graph write: version decision (SeleneDB)

After the user confirms the version bump:

INSERT (r:Release {
  version: $new_version,
  bump_type: $bump_type,
  date: date(),
  has_breaking_changes: $has_breaking
})
RETURN id(r) AS release_id

Link to session:

MATCH (s:Session) WHERE id(s) = $session_id
MATCH (r:Release) WHERE id(r) = $release_id
INSERT (s)-[:produced]->(r)

If there are breaking changes, link each to its code location:

MERGE (loc:CodeLocation {file: $file, function: $function})
MATCH (r:Release) WHERE id(r) = $release_id
INSERT (r)-[:breaking_change]->(loc)

4. Generate changelog

Compile changes from conventional commits since last release:

git log --oneline <last-tag>..HEAD --format="%s"

Organize by Keep a Changelog categories:

Added - feat: commits
Changed - commits that modify behavior
Fixed - fix: commits
Deprecated - changes marking items for removal
Removed - items removed in this release
Security - security-related fixes

Write human-readable descriptions, not raw commit messages. The changelog is for users, not contributors.

Present the generated changelog to the user for review:

"Here is the draft changelog for v[version]. Review and let me know:

Any entries to add, remove, or reword

Any entries miscategorized (e.g., marked as Added but should be Changed)

I will incorporate your feedback before proceeding to documentation verification."

Wait for approval before proceeding.

Graph write: changelog (SeleneDB)

After changelog approval, update the release node:

MATCH (r:Release) WHERE id(r) = $release_id
SET r.changelog = $changelog_content

5. Verify documentation

Delegate to the docs-sync skill methodology:

README reflects current capabilities
API documentation is current (cargo doc --no-deps)
CHANGELOG.md is updated with new entries
Version numbers in docs match the release version
Migration guide exists if there are breaking changes (use migration-guide)

6. Multi-crate workspace ordering

For workspace releases, determine release order from the dependency graph:

cargo tree --workspace --depth 1

Release crates in dependency order (leaves first, root last):

Crates with no internal dependencies
Crates that depend only on already-released crates
Repeat until all crates are released

For each crate:

Update version in Cargo.toml
Update internal dependency versions pointing to it
Run full CI check
Tag (but do not push until all crates are ready)

7. Pre-release checklist

Before tagging:

[ ] Version bumped in manifest (Cargo.toml / package.json / pyproject.toml)
[ ] Internal dependency versions updated
[ ] CHANGELOG.md updated with new version section
[ ] Breaking change detection passes (cargo-semver-checks / manual review)
[ ] Documentation is current (README, API docs, migration guide)
[ ] All tests pass
[ ] All lints pass
[ ] Security audit clean (cargo-audit / npm audit / pip-audit)
[ ] Breaking changes have a migration guide
[ ] Git tag format: v{version} (e.g., v1.3.0)

Rust additional:

[ ] cargo publish --dry-run succeeds
[ ] cargo package --list contains only intended files

Python additional:

[ ] python -m build produces clean wheel and sdist
[ ] twine check dist/* passes
[ ] py.typed marker present if typed

JavaScript additional:

[ ] npm pack --dry-run lists only intended files
[ ] .npmignore or files field in package.json is correct
[ ] types field points to valid .d.ts if TypeScript

8. Tag (do not push)

git tag -a v<version> -m "Release v<version>"

Report: "Release v<version> tagged and ready. Review the changelog and tag, then push when ready."

Do not push tags or publish. The user handles that.

Common Rationalizations

| Rationalization | Why It's Wrong | |---|---| | "Bump minor, changes are mostly features" | Skipping semver-checks misses breaking changes hidden in refactors. Run the tool. | | "Auto-generate changelog from commits" | Commit messages are for developers. Changelogs are for users. Translate. | | "Docs don't change for minor releases" | API docs, examples, and migration notes all drift. Verify every release. | | "Skip dry-run, package is fine" | Dry-runs catch packaging errors that tests don't cover. Minutes to run, hours to fix. | | "Breaking changes documented in git log" | Users don't read git logs. Write a migration guide they can find. |

Red Flags

Stop and reassess if you observe:

Bumping version without running semver-checks (or manual review for non-Rust)
Changelog entries that read like commit messages instead of user-facing language
Skipping the dry-run for package publishing
Tagging without completing the full pre-release checklist

Verification

[ ] Breaking changes detected via semver-checks or manual review
[ ] Version bump confirmed with user
[ ] Changelog written in user-facing language and approved
[ ] Documentation verified current (README, API docs, migration guides)
[ ] Tag created (not pushed — user handles that)

Guidance

Changelogs are for users, not developers. "Refactored internal module structure" is not a changelog entry. "Improved query performance by 30%" is.

When in doubt, bump major. An unnecessary major bump is inconvenient. A breaking change shipped as a minor bump breaks downstream consumers.

Pre-1.0 Cargo convention: For 0.y.z, changes in y are breaking (like major), changes in z are non-breaking (like minor). All 0.0.z releases are treated as incompatible with each other.

Multi-crate releases are atomic. Either all crates in the release succeed or none do. Tag all, then push all.

Test the release build. Run cargo package --list -p <crate> to see what would be published. Check for accidentally included files (test fixtures, build artifacts, secrets).

Push tags before publishing. Tags can be deleted if cargo publish fails. Published crates cannot be unpublished. Tag first, publish second.

Mitigation strategies for future releases: Use #[non_exhaustive] early on enums and structs. Deprecate before removing. Use sealed traits to prevent external implementations. Provide builder patterns instead of struct literals.
