[don-petry]

Summary

• Adds the missing agent-shield.yml workflow required by the org CI standards
• Follows the thin-caller pattern (same as claude.yml), delegating all logic to petry-projects/.github/.github/workflows/agent-shield-reusable.yml@main
• Triggers on PRs, issue/PR comments, and issue events

Closes #122

Generated with Claude Code

📝 Walkthrough

Walkthrough

A new GitHub Actions workflow file agent-shield.yml is added to configure automated agent shield checks triggered on pull requests, issues, and comments. The workflow delegates execution to a centralized reusable workflow maintained by the organization.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow .github/workflows/agent-shield.yml	New workflow configuration that responds to PR events (opened, reopened, synchronize), issue/PR comments, and issue events, delegating to a centralized org-level reusable workflow with restricted permissions (contents:read, pull-requests:read, issues:read).

Possibly related PRs

• feat: switch to org-level reusable Claude Code workflow #134 — Both PRs follow the same pattern of converting local workflow jobs into thin caller workflows that delegate to centralized org-level reusable workflows while managing permissions and secrets.

21-21: Pin reusable workflow to a full commit SHA instead of a branch.

Using @main is mutable and can change unexpectedly. GitHub's documentation and security guidance recommend pinning to a full commit SHA for immutability and safety—this prevents branch references from being moved to point to unintended code, including after a repository compromise. The tradeoff is that you'll need to actively update pins to receive fixes; Dependabot can help automate this.

🔧 Suggested hardening change

+    uses: petry-projects/.github/.github/workflows/agent-shield-reusable.yml@<full_commit_sha>

change this to pin the reusable workflow to a specific full commit SHA (e.g.,
replace "@main" with "@<full-commit-sha>") so the action is immutable and
auditable. Locate the "uses" line in .github/workflows/agent-shield.yml and
update it to reference the exact commit SHA of the petry-projects repository
(you can obtain the SHA from the upstream repo's commit history), and consider
adding a comment reminding maintainers to update the SHA via Dependabot or a
manual bump when you want upstream fixes.

CI Status Review

Most checks are passing. Two failures are noted:

1. autofix (FAILURE) — The autofix job ran prettier and found a formatting issue in .github/workflows/feature-ideation.yml (merged to main via feat: adopt org-wide feature-ideation reusable workflow #141). It committed the fix but failed to push it because the GitHub App token lacks workflows scope. This is a pre-existing issue not introduced by this PR — it affects any branch derived from main until GH_PAT_WORKFLOWS is configured for the autofix job too, or until feature-ideation.yml is manually reformatted.

2. SonarCloud Code Analysis (FAILURE) — This appears to be a pre-existing quality gate issue unrelated to the workflow file changes in this PR (no JS/TS was modified).

The core required checks all pass:

• ✅ build-and-test
• ✅ Node.js Tests
• ✅ coverage
• ✅ CodeQL
• ✅ Playwright UI Tests
• ✅ SonarCloud (workflow)

@don-petry — This PR addresses the compliance finding in #122 by adding the required agent-shield.yml workflow. The CI failures are pre-existing issues from main, not introduced by this change. Please review and merge when ready.
