A release workflow for the Matimo project. It reviews changes since the last version tag, chooses a semantic version change, updates package versions, runs checks, and prepares the release commit, tag, and notes.

Use it when preparing, verifying, and documenting a Matimo release across its packages.

It reduces the chance of inconsistent package versions or a release made before tests and validation pass. It also provides a repeatable process for deciding whether a change is a patch, minor, or major release.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00066	$0.00641
Opus 5.5	$0.00026	$0.00256
Sonnet 5.5	$0.00013	$0.00128
Haiku 4.5	$0.00007	$0.00064

Security

Grade A, and why

release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prepare release $ARGUMENTS. If no version given, inspect history and propose the next semver bump.

Step 1 — Assess changes since the last tag

git describe --tags --abbrev=0
git log $(git describe --tags --abbrev=0)..HEAD --oneline

Classify by conventional-commit prefix:

fix: / hotfix: → patch bump
feat: → minor bump
feat!: / BREAKING CHANGE: in body → major bump

Take the highest-severity bump found.

Step 2 — Confirm with the user

State the proposed version and why (e.g. "v0.1.2 → v0.2.0: 3 feat commits found, no breaking changes"). Wait for confirmation before changing any files.

Step 3 — Bump versions in lockstep

All packages share one version number. Update version in:

package.json                      (root)
packages/core/package.json
packages/cli/package.json
packages/slack/package.json
packages/gmail/package.json
packages/github/package.json
packages/hubspot/package.json
packages/notion/package.json
packages/postgres/package.json
packages/twilio/package.json
packages/mailchimp/package.json

Plus any packages added since the last release — check pnpm-workspace.yaml for the current authoritative list.

Also check for any pinned (non-workspace:*) cross-package version references that need updating.

Step 4 — Verify everything passes

pnpm install
pnpm build
pnpm test
pnpm validate-tools
pnpm lint

Do not proceed if anything fails. Fix issues, re-run, only continue once green.

Step 5 — Commit the version bump

git add package.json packages/*/package.json
git commit -m "chore: release vX.Y.Z"

Step 6 — Tag the release

git tag typescript/vX.Y.Z   # or python/vX.Y.Z; this repo tags each SDK separately

Show the push command but do not run it — ask the user to confirm first:

git push && git push --tags

Step 7 — Draft release notes

Summarize the commits from Step 1, grouped:

## What's New in vX.Y.Z

### New tools / packages
- ...

### Enhancements
- ...

### Bug fixes
- ...

### Breaking changes
- ... (omit section if none)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
