It uses regex-based pattern matching against 90 async-specific patterns across 6 categories, lefthook for git hook integration, and produces markdown reports with actionable remediation guidance. 100% local. Zero telemetry. ## Commands ### Free Tier (No license required) #### `asyncguard scan [file|directory]` One-shot async safety scan of files or directories. **How to execute:** ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target] ``` **What it does:** 1. Accepts a file path or directory (defaults to current directory) 2. Discovers all source files (skips .git, node_modules, binaries, images, .min.js) 3. Runs 30 async patterns against each file (free tier limit) 4. Calculates an async safety score (0-100) per file and overall 5. Grades: A (90-100), B (80-89), C (70-79), D (60-69), F (<60) 6. Outputs findings with: file, line number, check ID, severity, description, recommendation 7. Exit code 0 if score >= 70, exit code 1 if async quality is poor 8. Free tier limited to first 30 patterns (PM + AR categories) **Example usage scenarios:** - "Scan my code for async issues" -> runs `asyncguard scan .` - "Check this file for promise misuse" -> runs `asyncguard scan src/server.ts` - "Find resource leaks in my async code" -> runs `asyncguard scan src/` - "Audit async patterns in my project" -> runs `asyncguard scan .` - "Check for missing cancellation" -> runs `asyncguard scan .` ### Pro Tier ($19/user/month -- requires ASYNCGUARD_LICENSE_KEY) #### `asyncguard scan --tier pro [file|directory]` Extended scan with 60 patterns covering promise misuse, resource leaks, event loop blocking, and cancellation. **How to execute:** ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target] --tier pro ``` **What it does:** 1. Validates Pro+ license 2. Runs 60 async patterns (PM, AR, EL, CA categories) 3. Detects event loop blocking (sync I/O, sync crypto) 4. Identifies missing cancellation and abort handling 5. Full category breakdown reporting #### `asyncguard scan --format json [directory]` Generate JSON output for CI/CD integration. ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --format json ``` #### `asyncguard scan --format html [directory]` Generate HTML report for browser viewing. ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --format html ``` #### `asyncguard scan --category EL [directory]` Filter scan to a specific check category (PM, AR, EL, CA, AE, AC). ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --category EL ``` ### Team Tier ($39/user/month -- requires ASYNCGUARD_LICENSE_KEY with team tier) #### `asyncguard scan --tier team [directory]` Full scan with all 90 patterns across all 6 categories including async error patterns and coordination. **How to execute:** ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --tier team ``` **What it does:** 1. Validates Team+ license 2. Runs all 90 patterns across 6 categories 3. Includes async error pattern detection (swallowed rejections, async forEach, empty catch) 4. Includes coordination checks (unbounded concurrency, missing backpressure, no rate limit) 5. Full category breakdown with per-file results #### `asyncguard scan --verbose [directory]` Verbose output showing every matched line and pattern details. ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --verbose ``` #### `asyncguard status` Show license and configuration information. ```bash bash "<SKILL_DIR>/scripts/dispatcher.sh" status ``` ## Check Categories AsyncGuard detects 90 async anti-patterns across 6 categories: | Category | Code | Patterns | Description | Severity Range | |----------|------|----------|-------------|----------------| | **Promise/Future Misuse** | PM | 15 | Unhandled promises, async executor, nested .then chains, deferred antipattern | medium -- critical | | **Async Resource Leaks** | AR | 15 | Unclosed connections, missing dispose, dangling streams, leaked timers | medium -- critical | | **Event Loop Blocking** | EL | 15 | Sync file I/O, sync crypto, CPU loops, sync child process | low -- critical | | **Cancellation & Abortion** | CA | 15 | Missing AbortSignal, orphaned tasks, no cleanup on unmount | medium -- critical | | **Async Error Patterns** | AE | 15 | Swallowed rejections, empty .catch, async forEach, missing try/catch | medium -- critical | | **Async Coordination** | AC | 15 | Unbounded Promise.all, missing semaphore, no backpressure, no rate limit | medium -- critical | ## Tier-Based Pattern Access | Tier | Patterns | Categories | |------|----------|------------| | **Free** | 30 | PM, AR | | **Pro** | 60 | PM, AR, EL, CA | | **Team** | 90 | PM, AR, EL, CA, AE, AC | | **Enterprise** | 90 | PM, AR, EL, CA, AE, AC + priority support | ## Scoring AsyncGuard uses a deductive scoring system starting at 100 (perfect): | Severity | Point Deduction | Description | |----------|-----------------|-------------| | **Critical** | -25 per finding | Severe async issue (resource leaks, unhandled rejections, blocking I/O) | | **High** | -15 per finding | Significant async problem (missing cancellation, no error handler) | | **Medium** | -8 per finding | Moderate concern (coordination issues, missing backpressure) | | **Low** | -3 per finding | Informational / best practice suggestion | ### Grading Scale | Grade | Score Range | Meaning | |-------|-------------|---------| | **A** | 90-100 | Excellent async code quality | | **B** | 80-89 | Good async patterns with minor issues | | **C** | 70-79 | Acceptable but needs improvement | | **D** | 60-69 | Poor async quality | | **F** | Below 60 | Critical async problems | - **Pass threshold:** 70 (Grade C or better) - Exit code 0 = pass (score >= 70) - Exit code 1 = fail (score < 70) ## Configuration Users can configure AsyncGuard in `~/.openclaw/openclaw.json`: ```json { "skills": { "entries": { "asyncguard": { "enabled": true, "apiKey": "YOUR_LICENSE_KEY_HERE", "config": { "severityThreshold": "medium", "ignorePatterns": ["**/test/**", "**/fixtures/**", "**/*.test.*"], "ignoreChecks": [], "reportFormat": "text" } } } } } ``` ## Important Notes - **Free tier** works immediately with no configuration - **All scanning happens locally** -- no code is sent to external servers - **License validation is offline** -- no phone-home or network calls - Pattern matching only -- no AST parsing, no external dependencies beyond bash - Supports scanning all file types in a single pass - Git hooks use **lefthook** which must be installed (see install metadata above) - Exit codes: 0 = pass (score >= 70), 1 = fail (for CI/CD integration) - Output formats: text (default), json, html ## Error Handling - If lefthook is not installed and user tries hooks, prompt to install it - If license key is invalid or expired, show clear message with link to https://asyncguard.pages.dev/renew - If a file is binary, skip it automatically with no warning - If no scannable files found in target, report clean scan with info message - If an invalid category is specified with --category, show available categories ## When to Use AsyncGuard The user might say things like: - "Scan my code for async issues" - "Check my promise handling" - "Find resource leaks in async code" - "Detect event loop blocking" - "Are there any missing cancellation handlers?" - "Check for unhandled promise rejections" - "Audit my async error handling" - "Find missing AbortController usage" - "Check for synchronous I/O in async functions" - "Scan for async anti-patterns" - "Run an async code audit" - "Generate an async safety report" - "Check if my fetch calls have abort signals" - "Find empty catch handlers" - "Check my code for async coordination issues"
