Key Highlights:

• ✅ 62 workflows are clean with no style issues
• ℹ️ 5 workflows have minor shell scripting style improvements recommended
• 🔧 All issues are easily fixable with simple pattern replacements
• 📉 Significant improvement from previous scan (14 findings → 5 findings)

❌ poutine	Not Available	Supply chain scanner not found in PATH

Detailed Findings

1. SC2002: Useless Cat (4 occurrences)

Severity: Style (Low)
Impact: Performance - Creates unnecessary subprocess
Fix Difficulty: Easy

Affected Workflows:

1. copilot-agent-analysis.lock.yml - Line 162
2. copilot-pr-nlp-analysis.lock.yml - Line 185
3. copilot-pr-prompt-analysis.lock.yml - Line 162
4. prompt-clustering-analysis.lock.yml - Line 183

Pattern Found:

cat /tmp/gh-aw/pr-data/copilot-prs.json | /tmp/gh-aw/jqschema.sh > output.json

Recommended Fix:

/tmp/gh-aw/jqschema.sh < /tmp/gh-aw/pr-data/copilot-prs.json > output.json

Why This Matters:
Using cat file | command creates an unnecessary subprocess. Input redirection (<) or passing the file as an argument is more efficient and follows shell scripting best practices.

2. SC2236: Use -n instead of ! -z (1 occurrence)

Severity: Style (Low)
Impact: Readability - Double negative less clear
Fix Difficulty: Easy

Affected Workflow:

• copilot-session-insights.lock.yml - Line 193 (script line 63)

Pattern Found:

if [ ! -z "$session_id" ]; then
  echo "Downloading session: $session_id"
fi

Recommended Fix:

if [ -n "$session_id" ]; then
  echo "Downloading session: $session_id"
fi

Why This Matters:
Using ! -z "$var" (not empty) is a double negative. The -n operator (is not empty) is more idiomatic and clearer in intent.

Historical Trends

Comparing with the previous full scan from November 4, 2025 (evening):

Metric	Nov 4 (Evening)	Nov 5 (Today)	Change
Workflows Scanned	66	67	+1
Total Findings	14	5	-9 (-64%)
High Severity	0	0	-
Medium Severity	1	0	-1 ✅
Low Severity	9	5	-4 ✅
Info/Style	3	0	-3

Analysis of Changes

Positive Trends:

• ✅ 64% reduction in total findings (14 → 5)
• ✅ Medium severity issue resolved (excessive-permissions in copilot-pr-nlp-analysis)
• ✅ Several low severity issues resolved from previous scan
• ✅ One additional workflow scanned

Findings Resolved Since Nov 4:

1. ❌ SC2162 (read without -r) - No longer detected
2. ❌ SC2086 (unquoted variables) - No longer detected
3. ❌ Zizmor excessive-permissions - Not detected (tool unavailable)
4. ❌ Zizmor template-injection (9 occurrences) - Not detected (tool unavailable)

Note on Tool Availability:
Today's scan could only use actionlint. The previous scan (Nov 4) detected 10 zizmor findings (including template-injection and excessive-permissions issues). Since zizmor was not available today, we cannot confirm if those issues still exist or have been resolved.

Fix Suggestions

Priority 1: Fix SC2002 (Useless Cat) - 4 Workflows

This is the most common issue and can be fixed with a simple find-and-replace across 4 workflow files.

Copilot Agent Fix Prompt:

You are fixing a shell scripting style issue identified by actionlint/shellcheck.

**Task**: Remove "useless cat" patterns from workflow scripts

**Issue**: SC2002 - Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..' instead

**Files to Fix**:
1. .github/workflows/copilot-agent-analysis.md
2. .github/workflows/copilot-pr-nlp-analysis.md
3. .github/workflows/copilot-pr-prompt-analysis.md
4. .github/workflows/prompt-clustering-analysis.md

**Search for:**
```bash
cat /tmp/gh-aw/pr-data/copilot-prs.json | /tmp/gh-aw/jqschema.sh

Replace with:

/tmp/gh-aw/jqschema.sh < /tmp/gh-aw/pr-data/copilot-prs.json

Steps:

1. Read each of the 4 workflow markdown files
2. Replace the useless cat pattern with input redirection
3. Verify functionality is maintained
4. Create PR: "Fix SC2002: Remove useless cat patterns"

Reference: (redacted)

### Priority 2: Fix SC2236 (Use -n) - 1 Workflow

**Copilot Agent Fix Prompt:**

```markdown
You are fixing a shell scripting style issue identified by actionlint/shellcheck.

**Task**: Replace `! -z` with `-n` for string non-empty checks

**Issue**: SC2236 - Use -n instead of ! -z

**File to Fix**:
- .github/workflows/copilot-session-insights.md

**Search for:**
```bash
if [ ! -z "$session_id" ]; then

Replace with:

if [ -n "$session_id" ]; then

Steps:

1. Read .github/workflows/copilot-session-insights.md
2. Find the double-negative pattern in the session download loop
3. Replace with the more idiomatic -n operator
4. Create PR: "Fix SC2236: Use -n instead of ! -z in copilot-session-insights"

Reference: (redacted)

## Recommendations

### Immediate Actions
1. ✅ **Apply SC2002 fixes** - Low risk, high consistency improvement (4 workflows)
2. ✅ **Apply SC2236 fix** - Low risk, improved readability (1 workflow)
3. 🔄 **Verify previous issues** - Confirm if SC2162, SC2086 were actually fixed or if they're false negatives

### Short-term Actions
1. 🔧 **Install zizmor and poutine** in the workflow runner environment for comprehensive scanning
2. 🔍 **Re-run full scan** with all three tools to get complete security coverage
3. 📊 **Verify zizmor findings** from Nov 4 scan still exist or have been resolved

### Long-term Actions
1. 🏗️ **Establish automated static analysis** in CI/CD pipeline for all workflow changes
2. 📚 **Create workflow contribution guidelines** that include shellcheck compliance
3. 🔒 **Add pre-commit hooks** for actionlint, zizmor, and poutine
4. 📖 **Document common patterns** and anti-patterns for workflow authors

## Tool Installation Notes

For future scans, the following tools should be installed:

```bash
# Zizmor (Security scanner for GitHub Actions)
cargo install zizmor

# Poutine (Supply chain security scanner)
pipx install poutine

# Actionlint (Already installed)
go install github.com/rhysd/actionlint@latest

Conclusion

Today's scan shows significant improvement with a 64% reduction in total findings compared to the previous scan. All 5 remaining issues are minor shell scripting style improvements that pose no security or functional risks.

Status: ✅ HEALTHY

The repository's workflow security posture is strong, with only minor style issues remaining. Once the two simple fixes are applied, and zizmor/poutine are made available for comprehensive scanning, the workflow codebase will be in excellent condition.

Next Steps:

1. Apply the two straightforward fixes (SC2002 and SC2236)
2. Install missing tools (zizmor, poutine) for next scan
3. Continue daily monitoring to maintain code quality
