New Content Discovered

template-injection-prevention.md

Status: NEW FILE (discovered in this run)

Quality Assessment:

• Tone: ✅ Perfect technical tone, no marketing language
• Content: Detailed documentation of template injection security fix
• Examples: Clear code examples showing vulnerable and secure patterns
• References: Links to GitHub security documentation and issue 🔍 Static Analysis Report - November 14, 2025 #3945

Enhancement Made:
Added Mermaid data flow diagram comparing unsafe vs safe template injection patterns:

• Visual comparison of direct interpolation risk vs environment variable safety
• Color-coded risk indicators (red for unsafe, green for safe)
• Clear illustration of data flow through template expressions

Mermaid Diagrams Added

1. Template Injection Data Flow - specs/template-injection-prevention.md

Type: Flowchart (graph TB)
Purpose: Illustrate security difference between unsafe direct interpolation and safe environment variable pattern

graph TB
    subgraph "Unsafe Pattern"
        A1[Untrusted Input] --> B1["Template Expression(br/)${{ ... }}"]
        B1 --> C1[Direct Interpolation(br/)into Shell Command]
        C1 --> D1[Code Execution Risk]
        style D1 fill:#f88,stroke:#f00
    end

    subgraph "Safe Pattern"
        A2[Untrusted Input] --> B2["Template Expression(br/)${{ ... }}"]
        B2 --> C2[Environment Variable(br/)Assignment]
        C2 --> D2[Shell Receives(br/)Data Only]
        D2 --> E2[No Code Execution]
        style E2 fill:#8f8,stroke:#0f0
    end

Loading

Impact: Provides immediate visual understanding of the security vulnerability and its mitigation

2. Template Injection Data Flow - .github/instructions/developer.instructions.md

Type: Flowchart (graph TB)
Location: Security Best Practices > Template Injection Prevention section
Purpose: Same diagram integrated into consolidated documentation for easy reference

Additional Integration:

• Added "Recent Fixes (November 2025)" section documenting copilot-session-insights.md fix
• Reference to detailed analysis in specs/template-injection-prevention.md

Formatting Issues Identified

Missing Language Tags on Code Blocks

Issue: 28 code blocks across spec files use ``` without language tags (should be ```text)

Files Affected:

• code-organization.md: 17 blocks (file name listings, line counts)
• github-actions-security-best-practices.md: 4 blocks (command outputs, notes)
• capitalization.md: 3 blocks (text examples)
• firewall-log-parsing.md: 3 blocks (log outputs)
• validation-architecture.md: 1 block (example text)

Impact: Minor - Does not affect readability or rendering, but language tags improve Markdown linting and syntax highlighting

Recommendation: Optional fix - Can be addressed in a future run if desired

Recommendations

Immediate Actions

Optional: Add text language tags to 28 plain text code blocks for complete formatting consistency

Priority: Low - Does not impact readability

Future Improvements

1. Continue monitoring for new spec files that may need consolidation
2. Keep Mermaid diagrams updated if architecture changes
3. Monitor for any new patterns that require decision flow diagrams
4. Consider adding diagrams for any new security patterns

Maintenance

1. Continue daily consolidation reviews
2. Maintain technical tone in all new documentation
3. Ensure new spec files follow established patterns
4. Update developer.instructions.md when new major features are added
5. Keep decision trees and flowcharts up to date with code changes
