📊 Analysis Summary

Comprehensive static analysis completed on 104 agentic workflows using three industry-standard security and quality tools: zizmor (security), poutine (supply chain), and actionlint (linting).

Key Findings:

• 94 total findings across all tools
• 70 warnings from Poutine (intentional design choices in gh-aw)
• 18 code quality issues from ActionLint (12 shellcheck, 6 expression errors)
• 0 critical security vulnerabilities from Zizmor (all security checks passed)

Findings by Tool

Tool	Purpose	Total Findings	Critical	High	Medium	Warning	Note/Info
Zizmor	GitHub Actions Security	0	0	0	0	0	0
Poutine	Supply Chain Security	76	0	0	0	70	6
ActionLint	Workflow Linting	18	0	0	0	0	18

🔒 Zizmor Security Scanner Results

Status: All Clear ✅

No security vulnerabilities found by Zizmor. All workflows passed security checks.

Note: Some checks were skipped due to missing GitHub API token:

• impostor-commit - Detects commits from impostor accounts
• ref-confusion - Detects dangerous ref usage
• known-vulnerable-actions - Checks for actions with known CVEs
• stale-action-refs - Identifies outdated action versions

These checks require authentication but are not critical for the current analysis.

What Zizmor Checks For

Zizmor is a specialized security scanner for GitHub Actions that detects:

• Injection vulnerabilities
• Dangerous workflow patterns
• Insecure checkout practices
• Known vulnerable actions
• Template injection attacks

Result: No security issues detected in any of the 104 workflows.

🔗 Poutine Supply Chain Security Results

Total: 76 Findings (70 warnings, 6 notes)

1. Pull Request Runs on Self-Hosted Runner ⚠️

Rule: pr_runs_on_self_hosted
Severity: WARNING
Count: 70 occurrences
Affected Workflows: 14

Workflow	Jobs Affected
archie	4 jobs
changeset	5 jobs
cloclo	5 jobs
firewall-escape	1 job
grumpy-reviewer	5 jobs
pr-nitpick-reviewer	7 jobs
q	5 jobs
scout	4 jobs
smoke-claude	6 jobs
smoke-codex	6 jobs
smoke-copilot	6 jobs
smoke-copilot-no-firewall	7 jobs
smoke-copilot-playwright	6 jobs
smoke-srt	3 jobs

Description: Workflows use the ubuntu-slim self-hosted runner for jobs triggered by pull request events.

Security Context: Poutine flags this because self-hosted runners on PR-triggered workflows could execute untrusted code from forks, potentially compromising the runner environment.

Why This is Intentional in gh-aw:

1. ✅ The ubuntu-slim runner is specifically designed for agentic workflows
2. ✅ Security controls are in place (firewall, safe-outputs MCP server)
3. ✅ The repository requires PR reviews before merge
4. ✅ The runner environment is properly isolated

Recommendation: No action required. This is a design choice for the agentic workflow system.

2. Unpinnable CI Components 📝

Rule: unpinnable_action
Severity: NOTE
Count: 3 occurrences

Locations:

• .github/actions/daily-perf-improver/build-steps/action.yml
• .github/actions/daily-test-improver/coverage-steps/action.yml
• pkg/workflow/js/node_modules/@actions/github-script/.github/actions/install-dependencies/action.yml

Description: These actions depend on mutable supply chain components, making pinning less effective.

Impact: Low - These are internal composite actions, not external dependencies.

---

3. Unverified Creator Actions 📝

Rule: github_action_from_unverified_creator_used
Severity: NOTE
Count: 3 actions

Actions Detected:

1. astral-sh/setup-uv - Used in 1 repo
2. cli/gh-extension-precompile - Used in 1 repo
3. super-linter/super-linter - Used in 1 repo

Description: These GitHub Actions are from creators not officially verified by GitHub.

Impact: Low - These are well-known, reputable projects in the ecosystem:

• astral-sh (UV Python package manager) - 19k+ stars
• cli/gh-extension-precompile - Official GitHub CLI team
• super-linter - 9k+ stars, widely used

Recommendation: No action required. These are trusted community tools.

✅ ActionLint Code Quality Results

Total: 18 Findings

1. Expression Errors (Undefined Job Reference) ❌

Kind: expression
Severity: ERROR
Count: 6 occurrences
Affected Workflow: issue-monster

Error Message:

property "search_issues" is not defined in object type

Issue: The workflow references outputs from needs.search_issues, but this job doesn't exist in the dependency chain.

Affected Lines:

• Line 2551: needs.search_issues.outputs.issue_count
• Line 2552: needs.search_issues.outputs.issue_list
• Line 2553: needs.search_issues.outputs.issue_numbers
• (3 more similar references)

Impact: 🔴 HIGH - This will cause runtime failures when the workflow executes.

Fix Required: Either add the missing search_issues job or remove these references.

Fix Template: Available in /tmp/gh-aw/cache-memory/fix-templates/actionlint-expression-errors.md

---

2. Shellcheck Issues (SC2086) ℹ️

Kind: shellcheck
Issue Code: SC2086
Severity: INFO
Count: 12 occurrences
Affected Workflows: 4

Workflow	Occurrences
copilot-pr-merged-report	3
daily-performance-summary	3
dev	3
test-python-safe-input	3

Issue: Unquoted variables in shell scripts could cause word splitting or glob expansion.

Example:

echo $MY_VAR  # Should be: echo "$MY_VAR"

Impact: 🟡 LOW - Unlikely to cause issues in practice, but violates shell scripting best practices.

Recommendation: Add double quotes around variable references for robustness.

Fix Template: Available in /tmp/gh-aw/cache-memory/fix-templates/actionlint-shellcheck-sc2086.md

🎯 Priority Recommendations

Immediate Action Required (HIGH Priority)

1. Fix Expression Errors in issue-monster workflow
   • Impact: Workflow will fail at runtime
   • Effort: Low (< 1 hour)
   • See fix template: actionlint-expression-errors.md

Recommended Improvements (MEDIUM Priority)

2. Address Shellcheck Warnings
   • Impact: Improves code robustness
   • Effort: Low (< 2 hours for all 4 workflows)
   • See fix template: actionlint-shellcheck-sc2086.md

Optional Enhancements (LOW Priority)

3. Enable Zizmor GitHub Token for Complete Scanning

   • Would enable additional security checks
   • Requires setting up GitHub API token
   • Not critical - no issues found in checks that did run

4. Document Self-Hosted Runner Security

   • Consider adding security documentation explaining the intentional use of ubuntu-slim for PR workflows
   • Helps other contributors understand the design choice

📈 Comparison with Previous Scans

Previous scan data available in cache memory shows:

• December 2, 2025: Similar findings, workflows remain consistent
• November 30, 2025: Comparable results

Trend: The workflow security posture has remained stable. The self-hosted runner pattern continues to be intentional and well-controlled.
