+## [0.0.3] - 2026-03-09
+
+### Security
+
+- Removed runtime public-key override from host-side package signature verification; verification now always uses the pinned ClawSec key.
+- Removed unsigned-package override path in host-side verification flow.
+- Added strict package/signature path policy for signature verification (`/tmp`, `/var/tmp`, `/workspace/ipc`, `/workspace/project/data`, `/workspace/project/tmp`, `/workspace/project/downloads`) with absolute-path, extension, symlink, and realpath boundary checks.
+- Added policy-bound path enforcement for integrity approvals: approvals now require normalized paths that are explicitly present in non-ignored integrity policy targets.
+
+### Changed
+
+- Updated MCP signature verification tool docs and behavior to align with bounded path policy and pinned-key-only verification.
+- Added regression tests for signature-verification and integrity-approval hardening invariants.

-### Using Custom Public Keys
+### Public Key Policy

-For organizational deployments with custom skill publishers:
-
-```typescript
-// Load custom public key
-const customPublicKey = fs.readFileSync('/path/to/org-public.pem', 'utf8');
-
-// Verify with custom key (not pinned ClawSec key)
-const verification = await tools.clawsec_verify_skill_package({
-  packagePath: '/tmp/org-skill.tar.gz',
-  publicKeyPath: '/path/to/org-public.pem'  // Custom key
-});
-```
-
-**Note**: The MCP tool currently uses the pinned key. Custom key support via `publicKeyPem` parameter requires host-side implementation.
+The verifier always uses the pinned ClawSec public key from this skill package.
+Runtime public-key overrides are intentionally not supported.

+# ClawSec Scanner
+
+Comprehensive security scanner for agent platforms that automates vulnerability detection across multiple dimensions:
+
+- **Dependency Scanning**: Analyzes npm and Python dependencies using `npm audit` and `pip-audit` with structured JSON output parsing
+- **CVE Database Integration**: Queries OSV (primary), NVD 2.0, and GitHub Advisory Database for vulnerability enrichment
+- **SAST Analysis**: Static code analysis using Semgrep (JavaScript/TypeScript) and Bandit (Python) to detect hardcoded secrets, command injection, path traversal, and unsafe deserialization
+- **DAST Framework**: Agent-specific dynamic analysis with real OpenClaw hook execution harness (malicious input, timeout, output bounds, event mutation safety)
+- **Unified Reporting**: Consolidated vulnerability reports with severity classification and remediation guidance
+- **Continuous Monitoring**: OpenClaw hook integration for automated periodic scanning
+
+## Features
+
+### Multi-Engine Scanning
+
+The scanner orchestrates four complementary scan types to provide comprehensive vulnerability coverage:
+
+1. **Dependency Scanning**
+   - Executes `npm audit --json` and `pip-audit -f json` as subprocesses
+   - Parses structured output to extract CVE IDs, severity, affected versions
+   - Handles edge cases: missing package-lock.json, zero vulnerabilities, malformed JSON
+
+2. **CVE Database Queries**
+   - **OSV API** (primary): Free, no authentication, broad ecosystem support (npm, PyPI, Go, Maven)
+   - **NVD 2.0** (optional): Requires API key to avoid 6-second rate limiting
+   - **GitHub Advisory Database** (optional): GraphQL API with OAuth token
+   - Normalizes all API responses to unified `Vulnerability` schema
+
+3. **Static Analysis (SAST)**
+   - **Semgrep** for JavaScript/TypeScript: Detects security issues using `--config auto` or `--config p/security-audit`
+   - **Bandit** for Python: Leverages existing `pyproject.toml` configuration
+   - Identifies: hardcoded secrets (API keys, tokens), command injection (`eval`, `exec`), path traversal, unsafe deserialization
+
+4. **Dynamic Analysis (DAST)**
+   - Real hook execution harness for OpenClaw hook handlers discovered from `HOOK.md` metadata
+   - Verifies: malicious input resilience, timeout behavior, output amplification bounds, and core event mutation safety
+   - Note: Traditional web DAST tools (ZAP, Burp) do not apply to agent platforms - this provides agent-specific testing
+
+### Unified Reporting
+
+All scan types emit a consistent `ScanReport` JSON schema:
+
+```typescript
+{
+  scan_id: string;         // UUID
+  timestamp: string;       // ISO 8601
+  target: string;          // Scanned path
+  vulnerabilities: Vulnerability[];
+  summary: {
+    critical: number;
+    high: number;
+    medium: number;
+    low: number;
+    info: number;
+  }
+}
+```
+
+Each `Vulnerability` object includes:
+- `id`: CVE-2023-12345 or GHSA-xxxx-yyyy-zzzz
+- `source`: npm-audit | pip-audit | osv | nvd | github | sast | dast
+- `severity`: critical | high | medium | low | info
+- `package`: Package name (or 'N/A' for SAST/DAST)
+- `version`: Affected version
+- `fixed_version`: First version with fix (if available)
+- `title`: Short description
+- `description`: Full advisory text
+- `references`: URLs for more info
+- `discovered_at`: ISO 8601 timestamp
+
+### OpenClaw Integration
+
+Automated continuous monitoring via hook:
+
+- Runs scanner on configurable interval (default: 86400s / 24 hours)
+- Triggers on `agent:bootstrap` and `command:new` events
+- Posts findings to `event.messages` array with severity summary
+- Rate-limited by `CLAWSEC_SCANNER_INTERVAL` environment variable

+
+## Usage
+
+### On-Demand CLI Scanning
+
+```bash
+SCANNER_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-scanner"
+
+# Scan all skills with JSON output
+"$SCANNER_DIR/scripts/runner.sh" --target ./skills/ --output report.json --format json
+
+# Scan specific directory with human-readable output
+"$SCANNER_DIR/scripts/runner.sh" --target ./my-skill/ --format text
+
+# Check available flags
+"$SCANNER_DIR/scripts/runner.sh" --help
+```
+
+**CLI Flags:**
+- `--target <path>`: Directory to scan (required)
+- `--output <file>`: Write results to file (optional, defaults to stdout)
+- `--format <json|text>`: Output format (default: json)
+- `--check`: Verify all required binaries are installed
+
+### OpenClaw Hook Setup (Continuous Monitoring)
+
+Enable automated periodic scanning:
+
+```bash
+SCANNER_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-scanner"
+node "$SCANNER_DIR/scripts/setup_scanner_hook.mjs"
+```
+
+This creates a hook that:
+- Scans on `agent:bootstrap` and `command:new` events
+- Respects `CLAWSEC_SCANNER_INTERVAL` rate limiting (default: 86400 seconds / 24 hours)
+- Posts findings to conversation with severity summary
+- Recommends remediation for high/critical vulnerabilities
+
+Restart the OpenClaw gateway after enabling the hook, then run `/new` to trigger an immediate scan.
+
+### Environment Variables
+
+```bash
+# Optional - NVD API key to avoid rate limiting (6-second delays without key)
+export CLAWSEC_NVD_API_KEY="your-nvd-api-key"
+
+# Optional - GitHub OAuth token for Advisory Database queries
+export GITHUB_TOKEN="ghp_your_token_here"
+
+# Optional - Scanner hook interval in seconds (default: 86400 / 24 hours)
+export CLAWSEC_SCANNER_INTERVAL="86400"
+
+# Optional - Allow unsigned advisory feed during development (from clawsec-suite)
+export CLAWSEC_ALLOW_UNSIGNED_FEED="1"
+```
+
+## Architecture
+
+### Modular Design
+
+Each scan type is an independent module that can run standalone or as part of unified scan:
+
+```
+scripts/runner.sh              # Orchestration layer
+├── scan_dependencies.mjs      # npm audit + pip-audit
+├── query_cve_databases.mjs    # OSV/NVD/GitHub API queries
+├── sast_analyzer.mjs          # Semgrep + Bandit static analysis
+├── dast_runner.mjs            # Dynamic security testing orchestration
+└── dast_hook_executor.mjs     # Isolated real hook execution harness
+
+lib/
+├── report.mjs                 # Result aggregation and formatting
+├── utils.mjs                  # Subprocess exec, JSON parsing, error handling
+└── types.ts                   # TypeScript schema definitions
+
+hooks/clawsec-scanner-hook/
+├── HOOK.md                    # OpenClaw hook metadata
+└── handler.ts                 # Periodic scan trigger
+```
+
+### Fail-Open Philosophy
+
+The scanner prioritizes availability over strict failure propagation:
+
+- Network failures → emit partial results, log warnings
+- Missing tools → skip that scan type, continue with others
+- Malformed JSON → parse what's valid, log errors
+- API rate limits → implement exponential backoff, fallback to other sources
+- Zero vulnerabilities → emit success report with empty array
+
+**Critical failures** that exit immediately:
+- Target path does not exist
+- No scanning tools available (all bins missing)
+- Concurrent scan detected (lockfile present)
+
+### Subprocess Execution Pattern
+
+All external tools run as subprocesses with structured JSON output:
+
+```javascript
+import { spawn } from 'node:child_process';
+
+// Example: npm audit execution
+const proc = spawn('npm', ['audit', '--json'], {
+  cwd: targetPath,
+  stdio: ['ignore', 'pipe', 'pipe']
+});
+
+// Handle non-zero exit codes gracefully
+// npm audit exits 1 when vulnerabilities found (not an error!)
+proc.on('close', code => {
+  if (code !== 0 && stderr.includes('ERR!')) {
+    // Actual error
+    reject(new Error(stderr));
+  } else {
+    // Vulnerabilities found or success
+    resolve(JSON.parse(stdout));
+  }
+});
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**"Missing package-lock.json" warning**
+- `npm audit` requires lockfile to run
+- Run `npm install` in target directory to generate
+- Scanner continues with other scan types if npm audit fails
+
+**"NVD API rate limit exceeded"**
+- Set `CLAWSEC_NVD_API_KEY` environment variable
+- Without API key: 6-second delays enforced between requests
+- OSV API used as primary source (no rate limits)
+
+**"pip-audit not found"**
+- Install: `uv pip install pip-audit` or `pip install pip-audit`
+- Verify: `which pip-audit`
+- Add to PATH if installed in non-standard location
+
+**"Semgrep binary missing"**
+- Install: `pip install semgrep` OR `brew install semgrep`
+- Requires Python 3.8+ runtime
+- Alternative: use Docker image `returntocorp/semgrep`
+
+**"TypeScript hook not executable in DAST harness"**
+- The DAST harness executes real hook handlers and transpiles `handler.ts` files when a TypeScript compiler is available
+- Install TypeScript in the scanner environment: `npm install -D typescript` (or provide `handler.js`/`handler.mjs`)
+- Without a compiler, scanner reports an `info`-level coverage finding instead of a high-severity vulnerability
+
+**"Concurrent scan detected"**
+- Lockfile exists: `/tmp/clawsec-scanner.lock`
+- Wait for running scan to complete or manually remove lockfile
+- Prevents overlapping scans that could produce inconsistent results
+
+### Verification
+
+Check scanner is working correctly:
+
+```bash
+# Verify required binaries
+./scripts/runner.sh --check
+
+# Run unit tests
+node test/dependency_scanner.test.mjs
+node test/cve_integration.test.mjs
+node test/sast_engine.test.mjs
+node test/dast_harness.test.mjs
+
+# Validate skill structure
+python ../../utils/validate_skill.py .
+
+# Scan test fixtures (should detect known vulnerabilities)
+./scripts/runner.sh --target test/fixtures/ --format text
+```
+
+## Development
+
+### Running Tests
+
+```bash
+# All tests (vanilla Node.js, no framework)
+for test in test/*.test.mjs; do
+  node "$test" || exit 1
+done
+
+# Individual test suites
+node test/dependency_scanner.test.mjs  # Dependency scanning
+node test/cve_integration.test.mjs     # CVE database APIs
+node test/sast_engine.test.mjs         # Static analysis
+node test/dast_harness.test.mjs        # DAST harness execution
+```
+
+### Linting
+
+```bash
+# JavaScript/TypeScript
+npx eslint . --ext .ts,.tsx,.js,.jsx,.mjs --max-warnings 0
+
+# Python (Bandit already configured in pyproject.toml)
+ruff check .
+bandit -r . -ll
+
+# Shell scripts
+shellcheck scripts/*.sh
+```
+
+### Adding Custom Semgrep Rules
+
+Create custom rules in `.semgrep/rules/`:
+
+```yaml
+rules:
+  - id: custom-security-rule
+    pattern: dangerous_function($ARG)
+    message: Avoid dangerous_function - use safe_alternative instead
+    severity: WARNING
+    languages: [javascript, typescript]
+```
+
+Update `scripts/sast_analyzer.mjs` to include custom rules:
+
+```javascript
+const proc = spawn('semgrep', [
+  'scan',
+  '--config', 'auto',
+  '--config', '.semgrep/rules/',  // Add custom rules
+  '--json',
+  targetPath
+]);
+```
+
+## Integration with ClawSec Suite
+
+The scanner works standalone or as part of the ClawSec ecosystem:
+
+- **clawsec-suite**: Meta-skill that can install and manage clawsec-scanner
+- **clawsec-feed**: Advisory feed for malicious skill detection (complementary)
+- **openclaw-audit-watchdog**: Cron-based audit automation (similar pattern)
+
+Install the full ClawSec suite:
+
+```bash
+npx clawhub@latest install clawsec-suite
+# Then use clawsec-suite to discover and install clawsec-scanner
+```
+
+## Security Considerations
+
+### Scanner Security
+
+- No hardcoded secrets in scanner code
+- API keys read from environment variables only (never logged or committed)
+- Subprocess arguments use arrays to prevent shell injection
+- All external tool output parsed with try/catch error handling
+
+### Vulnerability Prioritization
+
+**Critical/High severity findings** should be addressed immediately:
+- Known exploits in dependencies (CVSS 9.0+)
+- Hardcoded API keys or credentials in code
+- Command injection vulnerabilities
+- Path traversal without validation
+
+**Medium/Low severity findings** can be addressed in normal sprint cycles:
+- Outdated dependencies without known exploits
+- Missing security headers
+- Weak cryptography usage
+
+**Info findings** are advisory only:
+- Deprecated API usage
+- Code quality issues flagged by linters
+
+## Roadmap
+
+### v0.0.2 (Current)
+- [x] Dependency scanning (npm audit, pip-audit)
+- [x] CVE database integration (OSV, NVD, GitHub Advisory)
+- [x] SAST analysis (Semgrep, Bandit)
+- [x] Real OpenClaw hook execution harness for DAST
+- [x] Unified JSON reporting
+- [x] OpenClaw hook integration
+
+### Future Enhancements
+- [ ] Automatic remediation (dependency upgrades, code fixes)
+- [ ] SARIF output format for GitHub Code Scanning integration
+- [ ] Web dashboard for vulnerability tracking over time
+- [ ] CI/CD GitHub Action for PR blocking on high-severity findings
+- [ ] Container image scanning (Docker, OCI)
+- [ ] Infrastructure-as-Code scanning (Terraform, CloudFormation)
+- [ ] Comprehensive agent workflow DAST (requires deeper platform integration)

+description: Periodic vulnerability scanning for installed skills and dependencies with configurable scan intervals.
+metadata: { "openclaw": { "events": ["agent:bootstrap", "command:new"] } }
+---
+
+# ClawSec Scanner Hook
+
+This hook performs comprehensive vulnerability scanning on installed skills and their dependencies on:
+
+- `agent:bootstrap`
+- `command:new`
+
+When triggered, it runs all configured scanning engines (dependency scan, SAST, DAST, CVE database lookup) and posts findings as conversation messages. Scans are rate-limited by configurable interval to avoid performance impact.
+
+## Scanning Capabilities
+
+The hook orchestrates four independent scanning engines:
+
+1. **Dependency Scanning**: Executes `npm audit` and `pip-audit` to detect known vulnerabilities in JavaScript and Python dependencies
+2. **SAST (Static Analysis)**: Runs Semgrep (JS/TS) and Bandit (Python) to detect security issues like hardcoded secrets, command injection, and path traversal
+3. **CVE Database Lookup**: Queries OSV API (primary), NVD 2.0 (optional), and GitHub Advisory Database (optional) for vulnerability enrichment
+4. **DAST (Dynamic Analysis)**: Executes real OpenClaw hook handlers in an isolated harness and tests malicious-input resilience, timeout behavior, output bounds, and event mutation safety
+
+## Safety Contract
+
+- The hook does not modify or delete skills.
+- It only reports findings and provides remediation guidance.
+- Scanning is non-blocking and runs on a configurable interval (default 24 hours).
+- Failed scans (network errors, missing tools) produce warnings but do not block execution.
+- Findings are deduplicated to avoid alert fatigue.
+
+## Optional Environment Variables
+
+### Core Configuration
+
+- `CLAWSEC_SCANNER_INTERVAL`: Minimum interval between hook scans in seconds (default `86400` / 24 hours).
+- `CLAWSEC_SCANNER_TARGET`: Override default scan target path (default: installed skills root).
+- `CLAWSEC_SCANNER_STATE_FILE`: Override state file path for deduplication (default `~/.openclaw/clawsec-scanner-state.json`).
+- `CLAWSEC_INSTALL_ROOT`: Override installed skills root directory.
+
+### CVE Database Integration
+
+- `CLAWSEC_NVD_API_KEY`: NVD API key for rate-limit-free access (without this, 6-second delays apply).
+- `GITHUB_TOKEN`: GitHub OAuth token for GitHub Advisory Database queries (optional enhancement).
+
+### Selective Scanning
+
+- `CLAWSEC_SKIP_DEPENDENCY_SCAN`: Set to `1` to disable dependency scanning (npm audit, pip-audit).
+- `CLAWSEC_SKIP_SAST`: Set to `1` to disable static analysis (Semgrep, Bandit).
+- `CLAWSEC_SKIP_DAST`: Set to `1` to disable dynamic analysis (hook security tests).
+- `CLAWSEC_SKIP_CVE_LOOKUP`: Set to `1` to disable CVE database enrichment.
+
+### Advanced Options
+
+- `CLAWSEC_SCANNER_TIMEOUT`: Maximum scan duration in seconds before timeout (default `300` / 5 minutes).
+- `CLAWSEC_SCANNER_FORMAT`: Output format for findings (`json` or `text`, default `text`).
+- `CLAWSEC_SCANNER_MIN_SEVERITY`: Minimum severity to report (`critical`, `high`, `medium`, `low`, `info`, default `medium`).
+- `CLAWSEC_SCANNER_OUTPUT_FILE`: Optional path to write full scan report JSON (default: conversation only).
+
+## Required Binaries
+
+The hook requires the following binaries to be available on `PATH`:
+
+- `node` (20+) - JavaScript runtime
+- `npm` - For npm audit execution
+- `python3` (3.10+) - Python runtime
+- `pip-audit` - Python dependency scanner
+- `semgrep` - JavaScript/TypeScript static analysis
+- `bandit` - Python static analysis
+- `jq` - JSON parsing and merging
+- `curl` - API requests (fallback)
+
+Missing binaries will be logged as warnings; available tools will still run.

+Usage: runner.sh --target <path> [options]
+
+Orchestrates vulnerability scanning across dependency, SAST, DAST, and CVE engines.
+
+Required:
+  --target <path>        Target directory to scan (e.g., ./skills/)
+
+Optional:
+  --output <file>        Write report to file (default: stdout)
+  --format <json|text>   Output format (default: json)
+  --skip-deps            Skip dependency scanning (npm audit, pip-audit)
+  --skip-cve             Skip CVE database enrichment
+  --skip-sast            Skip static analysis (Semgrep, Bandit)
+  --skip-dast            Skip dynamic analysis (hook security tests)
+  --help, -h             Show this help message
+
+Examples:
+  # Scan all skills with JSON output to file
+  ./runner.sh --target ./skills/ --output report.json
+
+  # Scan with human-readable output
+  ./runner.sh --target ./skills/ --format text
+
+  # Quick scan: dependencies only
+  ./runner.sh --target ./skills/ --skip-sast --skip-dast --skip-cve
+
+Environment Variables:
+  CLAWSEC_NVD_API_KEY           Optional NVD API key (avoids rate limiting)
+  GITHUB_TOKEN                  Optional GitHub token for Advisory Database
+  CLAWSEC_SCANNER_INTERVAL      Hook scan interval in seconds (default: 86400)

+# Module: ClawSec Scanner
+
+## Responsibilities
+- Provide multi-layer vulnerability scanning for OpenClaw-oriented skill repositories.
+- Orchestrate dependency, SAST, and DAST engines into a single report contract.
+- Execute real OpenClaw hook handlers in an isolated DAST harness to validate runtime security behavior.
+- Support periodic scan execution through an OpenClaw hook integration.
+- Normalize findings into severity buckets for downstream triage and automation.
+
+## Key Files
+- `skills/clawsec-scanner/skill.json`: skill metadata, SBOM paths, trigger phrases.
+- `skills/clawsec-scanner/scripts/runner.sh`: main orchestrator for dependency/SAST/DAST scans.
+- `skills/clawsec-scanner/scripts/scan_dependencies.mjs`: `npm audit` + `pip-audit` parsing.
+- `skills/clawsec-scanner/scripts/sast_analyzer.mjs`: Semgrep and Bandit execution/parsing.
+- `skills/clawsec-scanner/scripts/dast_runner.mjs`: hook discovery + real harness DAST evaluation.
+- `skills/clawsec-scanner/scripts/dast_hook_executor.mjs`: isolated per-hook runtime executor.
+- `skills/clawsec-scanner/hooks/clawsec-scanner-hook/handler.ts`: periodic OpenClaw event hook.
+- `skills/clawsec-scanner/lib/report.mjs`: unified report generation and text/JSON formatting.
+
+## Public Interfaces
+| Interface | Consumer | Behavior |
+| --- | --- | --- |
+| `runner.sh` CLI | Operators/automation | Runs all enabled scan engines and emits merged report output. |
+| `dast_runner.mjs` CLI | Operators/CI/hooks | Discovers hooks and runs isolated runtime DAST checks. |
+| OpenClaw scanner hook default export | OpenClaw runtime | Handles `agent:bootstrap` and `command:new` scanner trigger events. |
+| `ScanReport` JSON output | Humans and automation | Provides normalized severity summary + finding list. |
+
+## Inputs and Outputs
+Inputs/outputs are summarized in the table below.
+
+| Type | Name | Location | Description |
+| --- | --- | --- | --- |
+| Input | Scan target path | `--target` CLI arg | Root directory where skills/hooks are scanned. |
+| Input | Dependency manifests | `package-lock.json`, `requirements.txt`, `pyproject.toml` | Drives dependency vulnerability checks. |
+| Input | Hook metadata and handlers | `**/HOOK.md`, `handler.{js,mjs,cjs,ts}` | DAST harness discovers and executes these handlers. |
+| Input | Env configuration | `CLAWSEC_*`, `GITHUB_TOKEN` | Controls engine behavior, severity filtering, and output paths. |
+| Output | Unified scan report | stdout or `--output` file | JSON/text report with severity summary and finding details. |
+| Output | Runtime hook alerts | OpenClaw `event.messages` | New vulnerability alerts pushed into conversations. |
+| Output | Scanner state file | `~/.openclaw/clawsec-scanner-state.json` by default | De-duplication memory for reported finding IDs. |
+
+## Configuration
+| Variable | Default | Module Effect |
+| --- | --- | --- |
+| `CLAWSEC_SCANNER_INTERVAL` | `86400` | Minimum interval between periodic hook-triggered scans. |
+| `CLAWSEC_SCANNER_MIN_SEVERITY` | `medium` | Threshold for findings pushed to conversation alerts. |
+| `CLAWSEC_SCANNER_FORMAT` | `text` | Hook alert serialization format (`text` or `json`). |
+| `CLAWSEC_SKIP_DEPENDENCY_SCAN` | `0` | Disables dependency scanner when set to `1`. |
+| `CLAWSEC_SKIP_SAST` | `0` | Disables Semgrep/Bandit scanner when set to `1`. |
+| `CLAWSEC_SKIP_DAST` | `0` | Disables runtime hook DAST checks when set to `1`. |
+| `CLAWSEC_SKIP_CVE_LOOKUP` | `0` | Disables CVE enrichment stage when set to `1`. |
+| `CLAWSEC_DAST_HARNESS` | unset | Internal guard to avoid recursive scans during harness execution. |
+| `CLAWSEC_DAST_DISABLE_TYPESCRIPT` | unset | Test/debug switch forcing TypeScript harness coverage fallback mode. |
+
+## DAST Harness Behavior
+- Hook discovery walks the target tree for `HOOK.md` and resolves adjacent handler files.
+- Each declared event key is executed in a separate Node subprocess via `dast_hook_executor.mjs`.
+- Findings are generated from real runtime behavior:
+  - Baseline execution crash or timeout.
+  - Malicious-input crash or timeout.
+  - Output amplification beyond message/character thresholds.
+  - Core event identity mutation (`type`, `action`, `sessionKey`).
+- Harness capability gaps (for example missing TypeScript compiler for `.ts` handlers) are reported as `info` coverage findings, not high-severity vulnerabilities.
+
+## Example Snippets
+```bash
+# run scanner end-to-end
+bash skills/clawsec-scanner/scripts/runner.sh --target ./skills --format json
+```
+
+```bash
+# run DAST harness directly
+node skills/clawsec-scanner/scripts/dast_runner.mjs --target ./skills --format text --timeout 30000
+```
+
+## Tests
+| Test File | Focus |
+| --- | --- |
+| `skills/clawsec-scanner/test/dast_harness.test.mjs` | Real hook execution path, malicious crash detection, TypeScript coverage fallback semantics. |
+| `skills/clawsec-scanner/test/reviewer_regressions.test.mjs` | Runner behavior around non-zero DAST exit and merged reporting. |
+| `skills/clawsec-scanner/test/dependency_scanner.test.mjs` | Dependency scanner utility/report contracts. |
+| `skills/clawsec-scanner/test/sast_engine.test.mjs` | SAST parser/normalization behavior. |
+| `skills/clawsec-scanner/test/cve_integration.test.mjs` | OSV/NVD/GitHub enrichment integration checks. |
+
+## Update Notes
+- 2026-03-10: Added module page for `clawsec-scanner` and documented the `0.0.2` real OpenClaw DAST harness execution model.

Graceful error handling for network failures and API errors Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * auto-claude: subtask-5-1 - Create scripts/sast_analyzer.mjs to run Semgrep and Bandit Implemented static analysis engine following scan_dependencies.mjs pattern: - Runs Semgrep for JS/TS with --config auto and --json output - Runs Bandit for Python with -r <path> -f json -c pyproject.toml - Handles non-zero exit codes gracefully (tools exit 1 on findings) - Parses JSON output and converts to unified Vulnerability schema - Supports --target and --format CLI flags - Gracefully handles missing tools (semgrep, bandit) - Generates ScanReport with UUID scan_id and severity summary Verification passed: JSON output with valid vulnerabilities array Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * auto-claude: subtask-6-1 - Create scripts/dast_runner.mjs with basic security test framework - Implemented DAST framework with 4 security test cases: - DAST-001: Hook handler malicious input test (XSS, command injection, path traversal) - DAST-002: Hook handler timeout enforcement (30s default) - DAST-003: Hook handler resource limits (memory/CPU) - DAST-004: Hook handler event mutation safety - Supports --target, --format (json\|text), --timeout CLI flags - Returns unified ScanReport with vulnerability schema - Executes all test cases with configurable timeout - Tests malicious input patterns: XSS, SQL injection, command injection, path traversal, null bytes, large payloads - v1 scope: basic test framework for hook security testing (full agent workflow DAST is future work) Verification: - ✅ Framework loads and executes 4 test cases - ✅ Timeout enforcement working (30s default, configurable via --timeout) - ✅ JSON output with valid scan_id - ✅ Text format output working - ✅ Help output displays usage information * auto-claude: subtask-7-1 - Create scripts/runner.sh as main entry point with CLI flag parsing -
