release

name	release
description	Prepare and publish a new gem release — bumps version across all required files, validates tests/linting/MCP server, commits, and creates the GitHub release. Use this skill when the user says "release", "publish a new version", "bump the version", "cut a release", "prepare for release", "ship it", or any variation of wanting to publish a new gem version. Also use when the user asks about the release process or what steps are needed to release.

Release Workflow

Automate the full release lifecycle for the ClaudeMemory gem. This workflow was codified from the actual 0.9.0 release process.

The release has three phases: prepare (automated), publish (user-driven), and announce (automated). The middle phase requires user action because it pushes to a shared remote and publishes to RubyGems — destructive operations that must never happen without explicit confirmation.

Phase 1: Prepare

Step 1: Determine the new version

If a version was passed as an argument, use it. Otherwise, read the current version from lib/claude_memory/version.rb and ask the user what the new version should be.

Step 2: Find and update all version references

The version lives in exactly three files. Grep to confirm there are no others:

grep -rn "CURRENT_VERSION" --include="*.rb" --include="*.json" --include="*.gemspec" . | grep -v "CHANGELOG\|node_modules\|vendor\|\.git/"

Update all three:

1. lib/claude_memory/version.rb — the VERSION constant (canonical source)
2. .claude-plugin/plugin.json — the "version" field
3. .claude-plugin/marketplace.json — the "version" field inside the plugins array

If grep reveals any additional hardcoded references, update those too and flag them to the user as something that should be DRYed up.

Step 3: Update Gemfile.lock

bundle install

Verify both claude_memory (X.Y.Z) entries in Gemfile.lock match the new version.

Step 4: Verify MCP server reports the new version

The MCP server reads ClaudeMemory::VERSION dynamically. Confirm it picks up the change:

echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}' | bundle exec claude-memory serve-mcp 2>/dev/null | grep -o '"version":"[^"]*"'

Expected output: "version":"X.Y.Z" matching the new version. If it doesn't match, something is wrong with the require chain — investigate before proceeding.

Step 5: Run the full test suite

bundle exec rspec

All tests must pass. Do not proceed with any failures. Fix them first.

Step 6: Run the pre-release hook smoke gate

bin/pre-release-smoke

This script:

1. Re-runs bundle exec rake install so the PATH-resolved claude-memory binary matches the working tree.
2. Triggers each gem-managed hook against a temp DB.
3. Verifies every field listed in spec/smoke/expected_fields.yml is populated on the resulting activity_events.detail_json.
4. Exits non-zero with the missing field name(s) and since_version if any expected field is null/absent.

This catches the class of bug specs cannot: a code change that adds a new detail_json field but forgets rake install, leaving the installed gem stale and production hooks silently missing the field. Sprung that trap on 2026-04-16 (ActivityLog) and again on 2026-04-30 (#47 token-budget) — the gate is here so it can't happen a third time.

If the gate fails, stop the release, address the missing field (usually bundle exec rake install followed by re-running the gate), and only proceed when it exits 0.

Step 7: Run the benchmark scoreboard diff

bin/run-evals --benchmarks
bin/bench-diff

bin/run-evals --benchmarks writes spec/benchmarks/results/<version>.json — the diff-friendly snapshot of the current release's pass rates by category and per-scenario. bin/bench-diff then compares that snapshot against the most recent prior tagged version's scoreboard and exits non-zero if any tracked pass-rate dropped beyond the threshold (default -5%; configurable via --threshold).

The first release with this gate (0.12.0) has no prior scoreboard to compare against — bench-diff exits 0 with a "No baseline scoreboard available" note. From 0.13.0 onward it actively gates.

If the diff reports a regression, stop the release, investigate (the regressed metric path is named in stderr — e.g. metrics.evals.by_scenario.tech_stack_recall.pass_rate), and only proceed once you've either (a) fixed the regression or (b) made a deliberate decision that the lower pass rate is acceptable. If (b), document the new baseline in CHANGELOG so future-you isn't surprised.

For real-mode E2E coverage (~$2-8 per run), pass EVAL_MODE=real:

EVAL_MODE=real bin/run-evals --all && bin/bench-diff

Step 8: Run the linter

bundle exec rake standard:fix

Ensure no remaining violations.

Step 9: Verify CHANGELOG.md

The CHANGELOG should already have a release section written during development (via /improve, manual commits, or other workflow). Do not auto-generate release notes — they should reflect the actual development narrative.

Check that:

• The ## [X.Y.Z] - YYYY-MM-DD section exists with today's date
• It has Added, Changed, Fixed subsections as appropriate
• Upgrade Notes are included if there are breaking changes or manual migration steps
• The ## [Unreleased] section above it is empty or ready for the next cycle

If the CHANGELOG section is missing or incomplete, stop and ask the user. Do not fabricate release notes.

Step 10: Commit the version bump

git add lib/claude_memory/version.rb .claude-plugin/plugin.json .claude-plugin/marketplace.json Gemfile.lock
git commit -m "[Release] Bump version to X.Y.Z"

Do NOT push yet. Report what was committed and proceed to Phase 2.

Phase 2: Publish (User-Driven)

This phase involves pushing to a shared remote and publishing to RubyGems. These are irreversible shared-state operations — never execute them automatically.

Tell the user:

Version X.Y.Z is prepared and committed locally. To publish:

git push origin main
rake release

rake release will create the git tag, build the gem, and push to RubyGems. Let me know when that's done and I'll create the GitHub release.

Wait for the user to confirm before proceeding to Phase 3.

Phase 3: Announce

Step 11: Fix any stale "Latest" flags on GitHub releases

Check current release state:

gh release list --limit 5

If an older release is incorrectly marked "Latest" (this happens when releases are created out of order or with --latest set manually):

gh release edit v<old-version> --latest=false

Step 12: Create the GitHub release

Extract the release notes from CHANGELOG.md — everything between ## [X.Y.Z] and the next ## [ heading. Write to a temp file:

# Extract the section between the new version header and the next version header
sed -n '/^## \[X\.Y\.Z\]/,/^## \[/{ /^## \[X\.Y\.Z\]/d; /^## \[/d; p; }' CHANGELOG.md > /tmp/release-notes.md

Create the release:

gh release create vX.Y.Z \
  --title "vX.Y.Z — Short descriptive title" \
  --latest \
  --verify-tag \
  --notes-file /tmp/release-notes.md

The title should capture the theme of the release in a few words (e.g., "Predicate Design Overhaul, Reject/Restore, Telemetry"). Read the CHANGELOG to derive this — don't ask the user unless the theme isn't obvious.

Step 13: Verify the release

gh release list --limit 5

Confirm:

• The new release appears at the top
• It's marked "Latest"
• No older release is incorrectly marked "Latest"

Report the release URL to the user.

Error Handling

• Smoke gate fails (bin/pre-release-smoke exits non-zero): The script names the missing detail_json field and since_version in stderr. Most common cause: code that adds a new field landed without a follow-up bundle exec rake install, so the installed gem is stale. Re-run rake install, then re-run the gate. If the field was newly added but no rake install was run, that's the bug the gate is designed to catch — don't bypass it. If the manifest needs updating because a field was intentionally removed, edit spec/smoke/expected_fields.yml AND add a CHANGELOG breaking-change note (removing a detail_json field is a public API change per docs/api_stability.md §4).
• Bench-diff fails (bin/bench-diff exits 1): Stderr names the metric path that regressed (e.g. metrics.evals.by_scenario.tech_stack_recall.pass_rate). Investigate the regression — is it a real correctness issue, or a measurement-noise issue (e.g. real-mode flake)? If real, fix before releasing. If a deliberate baseline change (we knowingly traded N% in metric X for some other gain), update CHANGELOG with the new baseline and re-run with a temporarily looser --threshold to ship; the next release picks up the new floor automatically. Don't bypass the gate without an explicit baseline-change note — that defeats the entire scoreboard.
• Tests fail: Fix first. Never release with failing tests.
• CHANGELOG missing: Ask the user. Never fabricate release notes.
• Version already tagged: The tag may exist from a prior attempt. Ask the user whether to delete and recreate, or use a different version.
• gh not available: Tell the user to create the GitHub release manually, providing the release notes content.
• rake release fails: Common causes: not logged into RubyGems, tag already exists, uncommitted changes. Help the user diagnose but don't retry automatically.
