what

why

  • plugin.json declared "version": "1.0.0" at every commit since it was added, and claude plugin update compares declared versions, so installed plugins could never pick up new skills. Installs from months ago still serve the original 21 skills while agent-skills/skills/ now has 52.
  • Claude Code's plugin cache is version-scoped, so a version bump is what triggers a fresh copy of the skills.
  • Version Tracker (the json manager and format field, both added upstream in Atmos itself while this PR was in progress) replaces the shell-and-sed approach this started as: no template/rendered file pairs, and the manifests stay single-source files.
  • The security fixes were opportunistic, triggered by GitHub's Dependabot scan of this branch's push.

📝 Walkthrough

Walkthrough

The PR adds Atmos release version tracking for Claude plugin manifests and a stable-release workflow that opens or updates a signed pull request. It also updates website package overrides.

Changes

Plugin version tracking

Layer / File(s) Summary
Version tracking configuration and manifests
versions.lock.yaml, atmos.yaml, .claude-plugin/marketplace.json, agent-skills/.claude-plugin/plugin.json
The configuration tracks Atmos releases and updates version fields in the plugin manifests. The manifests now declare version 1.229.0.
Release-triggered update workflow
.github/workflows/build.yml
The Docker job exposes its image reference and tag. For stable releases, a dependent job runs version tracking in the built image, then creates or updates a signed pull request containing the manifests and lock file.

Website package overrides

Layer / File(s) Summary
Website package overrides
website/package.json
The pnpm overrides update brace-expansion, dompurify, and fast-uri versions, and add an image-size override.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 2cc0b

The plugin-version automation is ready to merge after normal checks. The previously identified image-reference and PR-check issues are addressed.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 2cc0b

The automation is release-gated and proposes changes through a PR rather than directly updating the default branch. Its main unresolved risk is that a container selected by a mutable tag runs alongside GitHub App credentials. Registry permissions and protection against tag replacement have not been established.

Retained concerns

  • Medium · security · observed: The new credential-bearing container job consumes an image tag rather than the producer’s signed digest. This introduces an artifact-identity gap at the GitHub App authority boundary; exploitation depends on unresolved registry mutation authority.
Security review details

Security Blast Radius

  • inferred — The immediate authority at risk is repository contents and PR writing. The App private key is also supplied to an action in the container job; compromise of that key could extend beyond the intended files to other authorized App installations, whose scope is not established.

Security Findings and Attack Paths

  • inferred — A conditional attack path is tag replacement after publication but before the plugin container pulls, followed by malicious execution in the credential-bearing job. No less-trusted actor with that mutation authority has been established. The supplied candidate remains deferred, and there are no retained verified findings.

Trust Boundaries and Controls

  • observed — The workflow separates read-only default credentials from App-backed writes, pins the checkout and App/PR actions, and disables checkout credential persistence. These controls constrain ordinary execution but do not authenticate the container against the producer’s signed digest. The selected PR paths are not a permission restriction on the App token.

Resilience and Maintainability Implications

  • inferred — Workflow concurrency and a fixed create-or-update branch limit competing proposals. Local manifest edits precede PR mutation, so interruption before that action does not itself publish them. Failure during PR mutation can leave branch or PR state; retry convergence and configured deletion depend on the external action’s behavior, which was not verified.

Hardening Proposals

  • proposed — Pass the producer’s digest to the plugin job and consume the image by digest. Where signature enforcement is required, verify the expected release identity before credential-bearing execution. Confirm effective registry writers and App installation scope to resolve the remaining exposure uncertainty.

This PR's own coverage is already fully green — codecov/patch and codecov/project both pass, and this diff has zero coverable lines (atmos.yaml, two JSON manifests, versions.lock.yaml, and a GitHub Actions workflow; no Go code touched).

The 84.29% figure in the report above is the whole-repo aggregate, not this PR's patch coverage. Moving that number to 85%+ would mean adding tests across the existing codebase, unrelated to what this PR does (pinning the Claude Code plugin's declared version to Atmos's own release version) — that's a separate, repo-wide effort, not something in scope here. Happy to take it on as its own PR if that's what's wanted; let me know.

…Tracker

The atmos@cloudposse plugin declared "version": "1.0.0" since it was
added, so `claude plugin update` could never detect new skills. Track
cloudposse/atmos's own latest release as a Version Tracker dependency and
write it into plugin.json and marketplace.json with the json file manager
(format: trimPrefix "v" so the manifests carry bare semver).

A new workflow runs `atmos version track update` and `apply` inside the
published atmos container image whenever a stable image lands on GHCR, and
opens a no-release PR with the refreshed manifests and lock file.

Closes #2895

…ry_package workflow

The image is pushed by build.yml with the default GITHUB_TOKEN, and GitHub
does not start workflow runs from events that token causes, so a
registry_package-triggered workflow would likely never fire. It would also
have read package_version.version, which can be a manifest digest rather
than a tag for multi-arch images.

Add the bump as a `needs: docker` job in build.yml instead (the same shape
as the homebrew job). It runs inside the exact image the docker job pushed,
using that job's image and tag outputs, and no longer needs its own trigger
filters. Also drop the workflow-level write permissions: the default token
only reads, and writes go through the GitHub App token.

- github.com/containerd/containerd/v2 v2.3.5 -> v2.3.6 (#299, medium):
  image-pull DoS via crafted OCI index graph amplification. Requires
  bumping go.mod's go directive to 1.26.8 -- containerd v2.3.6 itself
  declares that as its minimum Go version.
- fast-uri 3.1.6 -> 3.1.8 via pnpm override (#300, #301, both high):
  authority injection via unvalidated port, and host confusion via an
  unclosed bracket in the URI authority.
- image-size 2.0.2 -> 2.0.4 via a new pnpm override (#297, #298, both
  high): denial of service through infinite loops in the ICNS/JXL/HEIF
  parsers.

All three are patch/minor bumps within their existing major version,
inside dependabot.yml's semver-major ignore policy. NOTICE regenerated
for the two website dependency changes.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
- fast-uri 3.1.7 -> 3.1.8 via pnpm override (#308, medium): inconsistent
  host case normalization via percent-encoded octets. Already resolved
  to 3.1.8 by the prior fast-uri fix in this branch -- bumping the
  override floor to document the real requirement rather than leaving
  it implicit.
- dompurify 3.4.14 -> 3.4.16 via pnpm override (#309, low): detached
  subtree event handlers left armed after IN_PLACE sanitization.
- brace-expansion 1.1.18 -> 1.1.21 and 2.1.4 -> 2.1.7 via pnpm overrides
  (#302-#307, high/medium): three stacked DoS advisories per major line
  (uncontrolled recursion, then quadratic-time expansion).

All four are patch bumps within their existing major version, inside
dependabot.yml's semver-major ignore policy. NOTICE unchanged (no
license changes).

Not auto-fixed: three new CodeQL alerts (#6283-#6285, govulncheck
advisories GO-2022-0635/GO-2022-0646/GO-2026-5932 on deep transitive
deps -- aws-sdk-go's S3 Crypto SDK and x/crypto/openpgp usage) aren't
on this repo's established safe-fix-pattern list and need investigation
into which dependency actually pulls them in before attempting a fix.
