Release Manager

Automate the entire release lifecycle: version bump, changelog, README update, documentation sync, build, git tag, GitHub release, and publishing to PyPI/npm.

Architecture (summary)

Main agent orchestrates; heavy steps (scan files, generate changelog, update docs, update landing page) run as parallel subagents to keep context clean. See references/orchestration.md for the full architecture diagram, repo-sync rules, and subagent spawn details. If the Agent tool is unavailable, run the same logic inline.

Overview

A release typically involves these steps in order. Walk through each, confirming with the user before changes.

1. Pre-flight checks — clean working tree, synced with remote
2. Determine version — analyze changes, suggest semver bump
3. Bump version numbers — (subagent) scan and propose version changes
4. Generate changelog / release notes — (subagent) from git history and PRs
5. Update README — (subagent, combined with docs) version badges, changelog entries
6. Update documentation — (subagent) sync all project docs 6b. Update landing page — (subagent, runs in parallel with 3-6) if the project ships a landing page, refresh its version display, download/install CTA, "What's New", and feature highlights. Clean no-op when there's no landing page. Peer to the docs step, not part of it.
7. Build — run the project's build step if one exists
8. Commit, tag, push — create the release commit and tag
9. GitHub Release — publish on GitHub with release notes
10. Publish to registries — publish to PyPI and/or npm

Prerequisites

• Clean working tree (or user-approved stash)
• Local branch synced with origin (see references/orchestration.md for sync commands)
• For publishing: PyPI/npm credentials configured; for GitHub release: gh CLI authenticated

Repo Sync Before Edits (mandatory)

Before creating/updating/deleting files in an existing repository, sync the current branch with remote:

branch="$(git rev-parse --abbrev-ref HEAD)"
git fetch origin
git pull --rebase origin "$branch"

If the working tree is not clean, stash first, sync, then restore:

git stash push -u -m "pre-sync"
branch="$(git rev-parse --abbrev-ref HEAD)"
git fetch origin && git pull --rebase origin "$branch"
git stash pop

If origin is missing, pull is unavailable, or rebase/stash conflicts occur, stop and ask the user before continuing.

---

Step 1: Pre-flight Checks (inline)

If an existing release tool (.changeset, .releaserc, semantic-release config, etc.) is detected, defer to it instead of running the manual steps below — see "Check for existing release tools" further down in this step.

Verify the repo is in a clean state:

git status --porcelain
git rev-parse --abbrev-ref HEAD
git fetch origin
git status -sb

If there are uncommitted changes, ask the user whether to stash, commit, or abort. Never silently discard work.

Check for existing release tools

grep -E '"(release|version|publish)"' package.json 2>/dev/null
ls .releaserc* .changeset/ .versionrc* lerna.json 2>/dev/null

If found, tell the user: "This project uses <tool>. I'll run its release command instead of manual steps." and defer to that tool.

---

Step 2: Determine Version (inline)

Analyze changes since the last tag:

git tag --sort=-creatordate | head -10
git log $(git describe --tags --abbrev=0 2>/dev/null || echo "HEAD~50")..HEAD --oneline --no-merges

Recommend a bump using conventional commits:

• MAJOR — any BREAKING: or !: commits
• MINOR — any feat: (no breaking)
• PATCH — only fix:, docs:, chore:, refactor:, etc.

Present: "Based on N features, M fixes, K breaking changes since vX.Y.Z, I recommend vA.B.C. Confirm or override?" When in doubt, lean MINOR over PATCH.

---

Steps 3-6: Parallel Subagent Execution

Once the user confirms the version, spawn the four subagents (version-bumper, changelog-generator, docs-updater, landing-page-updater) in the same turn for parallel execution. The landing-page-updater first checks whether a landing page exists and skips cleanly if not; it edits only release-narrative content, leaving raw version-string bumps to the version-bumper so the two never touch the same line. After they finish, optionally spawn release-reviewer for a quality check (it also flags any cross-agent collision). See references/orchestration.md for the full workspace setup, agent spawn parameters, result collection, apply order, and apply-changes workflow.

---

Step 7: Build (inline)

Detect the build command:

[ -f package.json ] && grep -q '"build"' package.json && echo "npm run build"
[ -f Makefile ] && grep -q '^build:' Makefile && echo "make build"
[ -f Cargo.toml ] && echo "cargo build --release"
[ -f pyproject.toml ] && echo "python -m build"

Ask the user before running. If the build fails, stop and help debug — never continue with a broken build. If no build step exists, skip and tell the user.

---

Step 8: Commit, Tag, Push (inline)

Stage changed files (version bumps, changelog, README, docs) and commit:

git add <specific files that were changed>
git commit -m "chore(release): vX.Y.Z"
git tag -a vX.Y.Z -m "Release vX.Y.Z"

Confirm before pushing (see Acceptance Criteria):

git push origin <branch>
git push origin vX.Y.Z

---

Step 9: GitHub Release (inline)

If gh CLI is available and the repo is on GitHub:

gh release create vX.Y.Z \
  --title "vX.Y.Z" \
  --notes-file CHANGELOG.md \
  --latest

Append artifact paths (.tar.gz, .zip, binaries, .skill files) at the end of the command if any exist. Share the release URL with the user.

---

Step 10: Publish to Package Registries (inline)

If the project publishes to PyPI and/or npm, read references/publishing.md for the full workflow (pre-requisites, build, verify, upload, post-publish verification).

---

Expected Output

A successful release ends with the agent printing this expected output:

Release v2.4.0 complete.

Version bumped: pyproject.toml, package.json (1.3.1 → 2.4.0)
Changelog: CHANGELOG.md updated (8 commits: 3 features, 4 fixes, 1 breaking change)
Git tag: v2.4.0 (annotated) pushed to origin
GitHub release: https://github.com/owner/repo/releases/tag/v2.4.0
Published: PyPI — https://pypi.org/project/mypackage/2.4.0/

Post-release reminders:
- [ ] Announce on Discord
- [ ] Monitor for install issues (pip install mypackage==2.4.0)

Edge Cases

• No conventional commits — version bump cannot be auto-suggested. Show the raw commit list and ask the user to confirm the semver bump explicitly.
• No remote configured — git remote returns nothing. Skip push and GitHub release; offer a local tag only.
• Already published version — target version exists on PyPI/npm (detected via pip index versions or npm view). Abort the publish step and ask whether to bump again or skip publishing.
• Build artifacts missing — for projects requiring built artifacts, refuse to publish until Step 7 succeeds.

Acceptance Criteria

• Version string is bumped consistently in all detected files (e.g., pyproject.toml, package.json, __version__)
• CHANGELOG.md has a new entry for the release version
• Annotated git tag created and pushed to origin
• GitHub release created with notes when gh is available
• User is asked to confirm before each destructive or visible action (push, publish, GitHub release)
• Post-release checklist is presented after completion

Step Completion Reports

After each major step, output a status report. The full template and per-step variants live in references/step-reports.md. Quick form:

◆ [Step Name] (step N of M — context)
··································································
  Check 1:    √ pass
  Check 2:    × fail — reason
  Criteria:   √ N/M met
  ____________________________
  Result:     PASS | FAIL | PARTIAL

Post-Release Checklist

Remind the user about common follow-ups:

• Announce the release (blog, social, Discord, Slack)
• Bump to next dev version (e.g., X.Y.Z-dev) if the project uses that convention
• Close the GitHub milestone if one exists
• Monitor for issues
• Verify packages install (pip install pkg==X.Y.Z, npm install pkg@X.Y.Z)

Tips

• Confirmation gate for destructive/visible actions: see Acceptance Criteria
• For monorepos, handle each package's version independently
• Respect the existing CHANGELOG format — only add the new entry, don't reformat
• If a release goes wrong mid-way, help the user roll back: delete the tag locally and remotely, revert the commit
