AgentGuardian’s maintenance posture is public on purpose. If you’re evaluating us against another OSS red-teaming tool, you should be able to see — without reading commit logs — that someone is paying attention this week.

​
Cadence

The on-call release manager for the current week is recorded in MAINTAINERS.md.

​
What triggers a release

We cut a release when either condition is true:
  1. ## [Unreleased] in CHANGELOG.md has at least one bullet, and it is a Tuesday during the first-90-days window.
  2. A security fix is ready (any day, any week).
A week with zero shipped changes is not silently skipped — we either ship a docs/test-only patch release or post a one-line note in GitHub Discussions explaining the gap. Silence is the failure mode we are designing against.

​
How a release is cut

The release manager runs:
scripts/release.sh does five things and refuses to do anything else:
  1. Validates the working tree is clean and on main.
  2. Bumps src/agent_guardian/_version.py (hatch’s version source).
  3. Promotes ## [Unreleased] to ## [<version>] — <date> in CHANGELOG.md and inserts a fresh empty ## [Unreleased] stub.
  4. Creates a DCO-signed commit (chore(release): v<version>).
  5. Creates an annotated tag v<version> whose body is the new changelog section.
The tag push triggers .github/workflows/publish.yml, which builds the wheel + sdist reproducibly, generates a CycloneDX SBOM, signs every artifact with Sigstore, and publishes to PyPI via Trusted Publishing — no long-lived API tokens. The GitHub Release is created with the signed artifacts attached; the release manager pastes the changelog body into the Release notes textarea after the workflow goes green.

​
Changelog conventions

We follow Keep a Changelog and Semantic Versioning 2.0.

​
Section headings

​
Bullet style

During the M2 architecture push we wrote multi-paragraph bullets because they documented foundational work. Steady-state weeks should not ship that volume. The rule is:
  • One to two sentences per bullet. First sentence: what changed. Second sentence: why it matters to a user.
  • Link the PR or commit. Format: [#123](https://github.com/glacien-technologies/agent-guardian/pull/123).
  • Reference the test that locks it in, e.g. tests/unit/test_thing.py::test_specific_case.
Anything longer than three sentences belongs in a docs page or the release-announcement blog post, not in CHANGELOG.md.

​
Semver policy

Default-on behaviour changes are major even if the signature is unchanged. The v1.1.0 mode-default flip from smart to full is the reference case — it landed as a minor only because the prior default was not yet documented as stable.

​
Issue-response SLA

During the first-90-days window we promise:
  • Acknowledgement within 48 hours, Monday–Friday UTC. “Acknowledgement” means a maintainer has commented on the issue with either a triage label, a reproduction question, or a fix ETA. It does not mean the bug is fixed.
  • One human comment per week on every open issue, even if the comment is “still investigating.” Silence past seven days is a process failure, not a busy week.
  • Critical and security issues are acknowledged within 24 hours, any day. Use the private vulnerability-report channel in SECURITY.md for anything you would not want public.
The .github/workflows/stale-issue-responder.yml workflow enforces the back half of this promise mechanically:
  • After 21 days with no maintainer comment, the bot posts an acknowledgement and applies the stale label.
  • After a further 21 days with no further activity, the bot closes the issue with a pointer back to Discussions.
  • Issues labelled pinned, critical, security, or tracked are exempt from both steps.
The bot is the floor, not the ceiling. The expectation on maintainers is the 48-hour acknowledgement — the bot exists so a dropped ball is visible, not so triage can wait three weeks.

​
Where this is reported

If the README badge ever says “Active” and the PyPI release history disagrees by more than 30 days, that is a bug. File it in Discussions and the release manager will respond within the SLA above.
