Summary

  • Add an advisory CI job that runs harness-eval harness-lint against the
    repo's agent configuration (skills, CLAUDE.md, hooks, plugin config)
  • Uses the recommended preset (97 deterministic rules) pinned to harness-eval==7.9.0
  • Includes a baseline file to suppress pre-existing findings for incremental
    adoption. New findings introduced in future PRs will be caught.

About harness-eval

harness-eval is a
deterministic linter for AI code agent setups. It auto-detects agent tooling
(Claude Code, Cursor, Windsurf, Cline, Copilot, Gemini CLI, OpenCode), builds a
component graph, and runs 97 rules to catch issues like credential exfiltration,
prompt injection, broken references, and skill/hook conflicts.

Available as: CLI (pip install harness-eval), Claude Code plugin, GitHub
Action, Tekton Task, and Cursor commands. This PR integrates the CI version for
sdg_hub's GitHub Actions pipeline.

Test plan

  • CI job runs successfully on this PR
  • Verify findings are relevant (baseline any confirmed false positives)

Summary by CodeRabbit

  • Chores
    • Added automated quality checks for configuration and workflow changes.
    • Added baseline tracking for 19 known repository evaluation findings.
    • Quality checks now run for relevant changes submitted to or targeting the main branch.

Add an advisory CI job that runs harness-eval harness-lint against the

📝 Walkthrough

Walkthrough

The pull request adds a harness-eval baseline with 19 findings and integrates harness-eval harness-lint . into the lint workflow. The workflow also triggers for changes to Claude configuration and the baseline file.

Changes

Harness evaluation linting

Layer / File(s) Summary
Harness evaluation baseline
.harness-eval-baseline.json
The baseline records findings for Claude skills, Claude settings, and a GitHub action.
Lint workflow integration
.github/workflows/lint.yml
The workflow watches harness-related paths and runs harness-eval==7.9.2 with the recommended preset, fail-on-error behavior, and the baseline file.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 8d3f3

The new lint workflow can miss changes to covered configuration files, while the pull request can also update the baseline to suppress newly introduced findings. New agent-configuration issues could therefore merge without detection, so the PR is not merge-ready until these controls are fixed or explicitly accepted.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Add all harness-lint input paths to both path filters.

The baseline contains findings for .github/actions/free-disk-space/action.yml, but neither filter includes .github/actions/**. Changes to that action can bypass this job. The PR objective also names CLAUDE.md, but neither filter includes that path. Add the required paths to both push and pull_request.

Suggested additions
       - '.harness-eval-baseline.json'
+      - '.github/actions/**'
+      - 'CLAUDE.md'

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift

Prevent pull requests from self-approving baseline findings.

The job checks out the pull request and reads .harness-eval-baseline.json from that checkout. A pull request can add a new finding to the baseline, causing --fail-on-error to treat it as pre-existing. Compare against the target branch’s trusted baseline or require independent maintainer approval for baseline changes.
