httplint

HTTP client & server misconfiguration detector -- detects insecure connections, missing timeouts, cookie security issues, caching misconfigurations, and request handling vulnerabilities

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:

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 HTTP configuration patterns against each file (free tier limit)
4. Calculates an HTTP configuration quality 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 HTTP configuration quality is poor
8. 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 .

Pro Tier ($19/user/month -- requires HTTPLINT_LICENSE_KEY)

httplint scan --tier pro [file|directory]

Extended scan with 60 patterns covering HTTP client, server, cookie security, and caching headers.

How to execute:

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target] --tier pro

What it does:

1. Validates Pro+ license
2. Runs 60 HTTP patterns (HC, HS, CK, CH categories)
3. Detects cookie security issues (missing Secure flag, SameSite, session fixation)
4. Identifies caching and header misconfigurations
5. Full category breakdown reporting

httplint scan --format json [directory]

Generate JSON output for CI/CD integration.

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --format json

httplint scan --format html [directory]

Generate HTML report for browser viewing.

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --format html

httplint scan --category CK [directory]

Filter scan to a specific check category (HC, HS, CK, CH, RH, ER).

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --category CK

Team Tier ($39/user/month -- requires HTTPLINT_LICENSE_KEY with team tier)

httplint scan --tier team [directory]

Full scan with all 90 patterns across all 6 categories including request handling and error response.

How to execute:

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 request handling checks (input validation, content-length, redirects, smuggling)
4. Includes error and response checks (stack traces, status codes, error handling, response format)
5. Full category breakdown with per-file results

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
