C/C++ Static Analysis Tool (AI-Optimized)

Usage

# Check staged files (most common)
$SKILL_DIR/scripts/run_c_checks.sh --git-staged --project-root /path/to/project

# Check modified files
$SKILL_DIR/scripts/run_c_checks.sh --git-modified --project-root /path/to/project

# Check specific file
$SKILL_DIR/scripts/run_c_checks.sh -f code/main.c --project-root /path/to/project

# Check directory
$SKILL_DIR/scripts/run_c_checks.sh -d code/APP --project-root /path/to/project

Required: --project-root parameter must be provided.

Output Format

Default output is JSON with 5 sections:

{
  "summary": {
    "files_checked": 5,
    "errors": 1,
    "warnings": 8,
    "info": 1,
    "total": 10,
    "priority": "medium"  // high/medium/low
  },
  "issues_by_check": {
    "bugprone-macro-parentheses": {"count": 7},
    "clang-diagnostic-macro-redefined": {"count": 1}
  },
  "issues": [
    {"file": "code/main.c", "line": 48, "severity": "error", "message": "...", "check": "..."}
  ],
  "global_issues": [
    {"severity": "info", "message": "...", "check": "toomanyconfigs"}
  ],
  "top_files": [
    {"file": "code/xTarget.h", "issue_count": 4}
  ]
}

AI Processing Guide

1. Check priority: high → must fix errors, medium → suggest fixes, low → optional
2. Group by check: Use issues_by_check to identify common issues and provide unified fix
3. Focus on top_files: Prioritize files with most issues
4. Separate global_issues: Usually tool config warnings, show last or ignore
5. Provide fixes: Based on check field, give specific code examples

Response Template:

Analysis complete! Priority: {priority} ({errors}E/{warnings}W)

Main issues:
- {check-name} ({count}x) - {explanation}

Top files: {file} ({count} issues)

Fix suggestions:
1. {file}:{line} - {specific fix with code}

Options

• --severity error: Show only errors
• --ignore <pattern>: Ignore specific checks
• --format text|markdown: Alternative formats (not recommended for AI)

Exit Codes

• 0: No errors (warnings OK)
• 1: Errors found (must fix)
• 2: Tool error or invalid args
