Detailed Findings

Issue Type 1: Missing Step Definition (Expression Error)

Severity: Low
Count: 3 occurrences
Affected Workflows: artifacts-summary, changeset, daily-file-diet

Description:
Workflows reference steps.app-token.outputs.token but the app-token step is not properly defined with an ID in the workflow.

Impact:

• Validation failures in actionlint
• Potential runtime failures if step is truly missing
• Indicates possible compilation issues from markdown to YAML

Affected Locations:

• artifacts-summary.lock.yml:5086:29
• changeset.lock.yml:5727:29
• daily-file-diet.lock.yml:4535:29

Example:

# Current (causes error)
- uses: actions/checkout@v4
  with:
    github-token: ${{ steps.app-token.outputs.token }}
    # ^ references non-existent step

# Fix: Add step definition before usage
- name: Generate App Token
  id: app-token  # This ID is required
  uses: actions/create-github-app-token@v1
  with:
    app-id: ${{ secrets.GH_APP_ID }}
    private-key: ${{ secrets.GH_APP_PRIVATE_KEY }}

Issue Type 2: Shell Quoting (Shellcheck Info)

Severity: Info
Count: 3 occurrences (in same workflow)
Affected Workflows: release-highlights
Rule: SC2086

Description:
Shell variables should be double-quoted to prevent globbing and word splitting.

Impact:

• Potential unexpected behavior if variables contain spaces or special characters
• Code quality and robustness concern
• Not a security vulnerability in current context

Affected Locations:

• release-highlights.lock.yml:416:9 (3 instances within the same script)

Example:

# Current (shellcheck warning)
echo "RELEASE_TAG=$RELEASE_TAG" >> $GITHUB_ENV
PREV_PUBLISHED_AT=$(gh release view "$PREV_RELEASE_TAG" --json publishedAt --jq .publishedAt)
PR_COUNT=$(jq length /tmp/gh-aw/release-data/pull_requests.json)

# Fix: Add quotes
echo "RELEASE_TAG=$RELEASE_TAG" >> "$GITHUB_ENV"
PREV_PUBLISHED_AT=$(gh release view "$PREV_RELEASE_TAG" --json publishedAt --jq .publishedAt)
PR_COUNT=$(jq length "/tmp/gh-aw/release-data/pull_requests.json")

By Issue Type

Issue Type	Tool	Count	Severity	Affected Workflows
Missing app-token step	actionlint	3	Low	artifacts-summary, changeset, daily-file-diet

Other 84 workflows	0	✅ No issues

Fix Suggestion: Missing app-token Step

Issue: Expression validation error for steps.app-token.outputs.token
Severity: Low
Affected: 3 workflows

Fix Template

For each affected workflow, add the GitHub App token generation step before it's referenced:

# Add this step before any usage of steps.app-token.outputs.token
- name: Generate GitHub App Token
  id: app-token
  uses: actions/create-github-app-token@v1
  with:
    app-id: ${{ secrets.GH_APP_ID }}
    private-key: ${{ secrets.GH_APP_PRIVATE_KEY }}

# Then the existing usage will work
- uses: actions/checkout@v4
  with:
    github-token: ${{ steps.app-token.outputs.token }}

Workflow-Specific Fixes

artifacts-summary.lock.yml (Line 5086)

Add the app-token generation step before line 5086 where it's first referenced.

changeset.lock.yml (Line 5727)

Add the app-token generation step before line 5727 where it's first referenced.

daily-file-diet.lock.yml (Line 4535)

Add the app-token generation step before line 4535 where it's first referenced.

Root Cause Analysis

The issue likely stems from the markdown-to-YAML compilation process. The source markdown files may:

1. Reference the app-token step but not define it explicitly
2. Have the step defined but missing the id: attribute
3. Rely on implicit token generation that doesn't create an explicit step

Recommended Action: Review the source .md workflow files and ensure proper step definition with IDs.

Historical Trends

Comparison with Previous Scans

Scan Date	Total Findings	Tools Used	Change
2025-11-22	6	actionlint	Current
2025-11-20	73	zizmor, poutine, actionlint	-67 (-92%)
2025-11-18	1	(unknown)	+5

Trend Analysis

✅ Significant Improvement: The number of findings dropped from 73 (Nov 20) to 6 (Nov 22), a 92% reduction.

Notes:

• The Nov 20 scan used all three tools (zizmor, poutine, actionlint) and found 73 low-severity issues
• Today's scan only used actionlint, which may explain part of the difference
• However, even comparing actionlint-only results, there's a notable improvement in code quality
• The reduction suggests that previous findings were addressed or the workflows were improved

Cannot Compare Security Findings: Since zizmor and poutine were not available today, we cannot assess whether the security posture has improved, degraded, or remained stable since Nov 20.

Recommendations

Immediate Actions (Priority 1)

1. Fix app-token step definitions in 3 workflows:

   • artifacts-summary
   • changeset
   • daily-file-diet
   • Estimated effort: 15 minutes per workflow
   • Impact: Resolves all expression validation errors

2. Update shell scripts in release-highlights:

   • Add quotes around variables in 3 locations
   • Estimated effort: 5 minutes
   • Impact: Improves code robustness

Short-term Actions (Priority 2)

3. Complete zizmor installation:

   • Monitor cargo install process or use pre-built binaries
   • Re-run scan with zizmor to assess security vulnerabilities
   • Estimated effort: 30 minutes
   • Impact: Comprehensive security assessment

4. Investigate poutine installation:

   • Determine correct installation method (not available via pip)
   • Check if it requires Go, npm, or binary download
   • Estimated effort: 20 minutes
   • Impact: Supply chain security assessment

5. Review workflow compilation process:

   • Investigate why app-token steps are not compiled correctly
   • Update markdown-to-YAML compiler if needed
   • Estimated effort: 1-2 hours
   • Impact: Prevents similar issues in future workflows

Long-term Actions (Priority 3)

6. Automate static analysis in CI/CD:

   • Add actionlint, zizmor, and poutine to pre-commit hooks
   • Run on every workflow change
   • Estimated effort: 2-3 hours
   • Impact: Catches issues before merge

7. Create workflow templates with proper patterns:

   • Include proper step IDs
   • Add shell quoting best practices
   • Estimated effort: 3-4 hours
   • Impact: Reduces common errors in new workflows

8. Establish severity thresholds:

   • Define acceptable levels for each tool
   • Block merges on Critical/High findings
   • Estimated effort: 1 hour (policy decision)
   • Impact: Maintains security baseline
