HTTPLint -- HTTP Client & Server Misconfiguration Detector
HTTPLint scans codebases for HTTP client/server misconfigurations, insecure connections, missing timeouts, cookie security issues, caching misconfigurations, header problems, and request handling vulnerabilities. It uses regex-based pattern matching against 90 HTTP-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)
httplint scan [file|directory]
One-shot HTTP configuration scan of files or directories.
How to execute:
bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target]
What it does:
- Accepts a file path or directory (defaults to current directory)
- Discovers all source files (skips .git, node_modules, binaries, images, .min.js)
- Runs 30 HTTP configuration patterns against each file (free tier limit)
- Calculates an HTTP configuration quality score (0-100) per file and overall
- Grades: A (90-100), B (80-89), C (70-79), D (60-69), F (<60)
- Outputs findings with: file, line number, check ID, severity, description, recommendation
- Exit code 0 if score >= 70, exit code 1 if HTTP configuration quality is poor
- Free tier limited to first 30 patterns (HC + HS categories)
Example usage scenarios:
- "Scan my code for HTTP issues" -> runs
httplint scan .
- "Check this file for HTTP misconfigurations" -> runs
httplint scan src/server.ts
- "Find insecure HTTP connections" -> runs
httplint scan src/
- "Audit HTTP configuration quality in my project" -> runs
httplint scan .
- "Check for cookie security issues" -> runs
httplint scan .

httplint scan --tier team [directory]
Full scan with all 90 patterns across all 6 categories including request handling and error response.
How to execute:

httplint scan --verbose [directory]
Verbose output showing every matched line and pattern details.
bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --verbose
httplint status
Show license and configuration information.
bash "<SKILL_DIR>/scripts/dispatcher.sh" status
Check Categories
HTTPLint detects 90 HTTP misconfiguration patterns across 6 categories:
| Category | Code | Patterns | Description | Severity Range |
|---|
| HTTP Client | HC | 15 | Missing timeouts, no retries, insecure connections, hardcoded URLs, missing User-Agent | medium -- critical |
| HTTP Server | HS | 15 | Missing CORS configuration, no rate limiting, improper status codes, missing middleware | medium -- critical |
| Cookie & Session | CK | 15 | Missing Secure flag, no SameSite attribute, session fixation, insecure token storage | high -- critical |
| Caching & Headers | CH | 15 | Missing cache control, no ETags, missing security headers, improper content type | medium -- high |
| Request Handling | RH | 15 | Missing input validation, content-length issues, open redirects, request smuggling | high -- critical |
| Error & Response | ER | 15 | Stack trace exposure, improper status codes, missing error handling, response format issues | medium -- high |
Tier-Based Pattern Access
| Tier | Patterns | Categories |
|---|
| Free | 30 | HC, HS |
| Pro | 60 | HC, HS, CK, CH |
| Team | 90 | HC, HS, CK, CH, RH, ER |
| Enterprise | 90 | HC, HS, CK, CH, RH, ER + priority support |
Scoring
HTTPLint uses a deductive scoring system starting at 100 (perfect):
| Severity | Point Deduction | Description |
|---|
| Critical | -25 per finding | Severe security issue (insecure connections, missing authentication) |
| High | -15 per finding | Significant quality problem (missing timeouts, no CORS) |
| Medium | -8 per finding | Moderate concern (missing headers, caching issues) |
| Low | -3 per finding | Informational / best practice suggestion |
Grading Scale
| Grade | Score Range | Meaning |
|---|
| A | 90-100 | Excellent HTTP configuration quality |
| B | 80-89 | Good configuration with minor issues |
| C | 70-79 | Acceptable but needs improvement |
| D | 60-69 | Poor HTTP configuration quality |
| F | Below 60 | Critical HTTP configuration problems |
- Pass threshold: 70 (Grade C or better)
- Exit code 0 = pass (score >= 70)
- Exit code 1 = fail (score < 70)
Configuration
Users can configure HTTPLint in ~/.openclaw/openclaw.json:
{
"skills": {
"entries": {
"httplint": {
"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://httplint.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
