description: >
  Find and remove dead code in JavaScript/TypeScript projects. Detects unused exports,
  unreferenced files, orphaned components, unused dependencies, and dead functions/variables.
  Supports monorepos, path aliases, barrel exports, and dynamic imports.
  Use when asked to find dead code, detect unused exports, clean up unused files,
  find orphaned modules, audit code for unused functions, remove dead code,
  identify unused dependencies, or reduce bundle size by removing unused code.
  Triggers on "dead code", "unused exports", "unused files", "orphan", "tree shake",
  "unused imports", "unused dependencies", "code cleanup", "reduce bundle".

# Dead Code Finder

Detect and report dead code in JavaScript/TypeScript projects.

## Quick Start

```bash
# Full scan — unused exports, files, and dependencies
python3 scripts/find_dead_code.py /path/to/project

# Exports only
python3 scripts/find_dead_code.py /path/to/project --mode exports

# Unused files only
python3 scripts/find_dead_code.py /path/to/project --mode files

# Unused dependencies only
python3 scripts/find_dead_code.py /path/to/project --mode deps

# JSON output for programmatic use
python3 scripts/find_dead_code.py /path/to/project --json
```

## What It Detects

### 1. Unused Exports
Exported functions, classes, constants, types, and interfaces never imported anywhere.
- Named exports (`export function foo`, `export const bar`)
- Re-exports (`export { x } from './y'`)
- Type exports (`export type`, `export interface`)
- Barrel file analysis (index.ts re-exports)

### 2. Unreferenced Files
Files never imported by any other file in the project.
- Skips entry points (configurable)
- Skips test files, config files, and scripts by default
- Handles path aliases (tsconfig paths)

### 3. Unused Dependencies
npm packages in package.json never imported in code.
- Checks `dependencies` and `devDependencies`
- Recognizes CLI tools as potentially used
- Handles scoped packages and subpath imports

## Configuration

Default entry points: `src/index.{ts,tsx,js,jsx}`, `src/main.*`, `src/app.*`, `pages/**/*`, `app/**/*`.

Default ignores: `node_modules`, `dist`, `build`, `.next`, `coverage`, `__tests__`, `*.test.*`, `*.spec.*`, `*.config.*`, `*.d.ts`.

Override via flags:
```bash
--entry "src/main.ts,src/worker.ts"
--ignore "generated,vendor"
```

## Interpreting Results

```
=== Dead Code Report ===

UNUSED EXPORTS (12 found):
  src/utils/helpers.ts: formatDate, parseQuery, slugify
  src/components/Button.tsx: ButtonProps (type)
  src/api/client.ts: createClient

UNREFERENCED FILES (3 found):
  src/legacy/oldAuth.ts
  src/utils/deprecated.ts
  src/components/unused/Card.tsx

UNUSED DEPENDENCIES (2 found):
  moment
  lodash.merge
```

## Workflow

1. Run scan on the project
2. Review report — some findings may be false positives (dynamic imports, reflection)
3. Verify each finding before removing
4. Remove confirmed dead code
5. Run tests to confirm nothing broke

## Limitations

- Dynamic imports with variable paths may cause false positives
- Code consumed by external packages (libraries) shows as unused
- CSS/SCSS imports not tracked
- `export *` partially supported

FILE:STATUS.md
# dead-code-finder — Status

**Status:** Ready
**Price:** $59
**Created:** 2026-03-29

## What It Does
Finds dead code in JS/TS projects: unused exports, unreferenced files, and unused npm dependencies. Pure Python, no external dependencies. Supports path aliases, barrel exports, scoped packages.

## Components
- `scripts/find_dead_code.py` — main scanner (regex-based, no AST parser needed)
- Tested on synthetic project with mixed used/unused code

## Next Steps
- [ ] Publish to ClawHub (after April 11 — GitHub account age requirement)
- [ ] Add Python/Go support in v2
- [ ] Add `--fix` mode for auto-removal

# Env Config Validator

Validate .env files, compare environments, detect common mistakes, and enforce schemas.

## Quick Start

```bash
# Validate with auto-detected common checks
python3 scripts/validate_env.py .env

# Validate against a schema
python3 scripts/validate_env.py .env --schema env-schema.json

# Compare dev vs prod

## Common Checks (Auto-Detected)

The validator automatically detects these issues without a schema:

| Check | Severity | What it catches |
|-------|----------|-----------------|
| Trailing whitespace | warning | Invisible chars causing bugs |
| Unquoted spaces | warning | Values with spaces not wrapped in quotes |
| Placeholders | error | `change_me`, `TODO`, `xxx`, `your_*` values |
| Empty values | info | Defined but blank variables |
| Double-nested quotes | warning | `""value""` quoting errors |
| URL missing protocol | warning | URL vars without http(s):// |
| Port out of range | error | Port > 65535 or < 1 |
| Short secrets | warning | SECRET/PASSWORD/KEY < 8 chars |
| Inconsistent booleans | info | `yes`/`1` instead of `true`/`false` |
| Mixed case keys | info | `some_Var` instead of `SOME_VAR` |
| Inline comments | warning | `value # comment` (not all parsers support) |
| Duplicate keys | warning | Same variable defined twice |

## Options

| Flag | Default | Description |
|------|---------|-------------|
| `--schema` | — | JSON schema file for type/required validation |
| `--diff FILE FILE` | — | Compare two env files |
| `--generate-schema` | — | Auto-generate schema from .env file |
| `--output` | text | Output format: text, json, markdown |
| `-o` | stdout | Output file path |
| `--ignore` | — | Skip specific check IDs (repeatable) |
| `--severity` | info | Minimum severity: error, warning, info |

## Exit Codes

- `0` — No issues (or only info)
- `1` — Warnings found (or diff has differences)
- `2` — Errors found

## Workflow

### Pre-deploy Validation

1. Generate schema from working .env: `--generate-schema .env -o schema.json`
2. Add schema to repo, validate in CI: `validate_env.py .env --schema schema.json --severity error`
3. Diff staging vs prod: `--diff .env.staging .env.production`

### Audit Existing Project

1. Run `validate_env.py .env` to find common mistakes
2. Fix errors and warnings
3. Generate schema for future validation

# env-config-validator — Status

**Status:** Ready
**Price:** $49
**Built:** 2026-03-30

## Features
- 12 common mistake detectors (placeholders, trailing spaces, invalid ports, etc.)
- Schema validation with type checking, required vars, patterns, ranges
- Environment diff (dev vs prod) with secret masking
- Auto-generate schema from existing .env
- 3 output formats (text, JSON, markdown)
- CI-friendly exit codes
- Handles export prefix, quoted values, comments

## Tested
- Common checks with 15 detected issues
- Schema generation and validation
- Environment diff with secret masking
- JSON and markdown output
- Severity filtering
- Edge cases (empty values, duplicates, inline comments)

FILE:log.md
# env-config-validator — Log

## 2026-03-30

### Done
- Built complete .env validator
- Script: `scripts/validate_env.py` (~400 lines Python stdlib)
- Reference: `references/schema-format.md` — schema JSON spec, types, fields
- 12 common mistake detectors, 10 supported types
- Schema validation, env diff, auto-generate schema
- 3 output formats, CI-friendly exit codes
- Tested: common checks, schema gen/validation, diff, all outputs
- Packaged to `dist/env-config-validator.skill` ✅

### Decisions
- $49 pricing — entry-level, high volume potential
- Pure Python stdlib
- Secret masking in diff output (first 3 chars + ***)

# Schema Format Reference

## Schema JSON Structure

```json
{
  "variables": {
    "VARIABLE_NAME": {
      "type": "string",
      "required": true,
      "description": "What this variable does",
      "pattern": "^regex$",
      "default": "default_value",
      "example": "example_value",
      "sensitive": false,
      "min": 0,
      "max": 65535
    }
  }
}
```

## Field Reference

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `type` | string | no | Expected type (see below) |
| `required` | boolean | no | Whether variable must exist |
| `description` | string | no | Human-readable description |
| `pattern` | string | no | Regex pattern for validation |
| `default` | string | no | Default value (informational) |
| `example` | string | no | Example value (informational) |
| `sensitive` | boolean | no | If true, mask in diff output |
| `min` | number | no | Minimum for numeric values |
| `max` | number | no | Maximum for numeric values |

## Supported Types

| Type | Validates | Examples |
|------|-----------|---------|
| `string` | Any value | `production`, `hello world` |
| `integer` | Digits only | `3000`, `10` |
| `float` | Decimal number | `0.5`, `3.14` |
| `boolean` | true/false/yes/no/1/0/on/off | `true`, `false` |
| `url` | Protocol prefix required | `https://api.example.com` |
| `email` | [email protected] format | `[email protected]` |
| `ip` | IPv4 dotted notation | `192.168.1.1` |
| `port` | 1-65535 | `3000`, `8080` |
| `path` | Starts with / or ~ | `/var/log/app.log` |
| `connection_string` | postgres/mysql/redis/etc:// | `postgres://user:pass@host/db` |

## Auto-Generated Schema

Use `--generate-schema .env` to create a schema from an existing file. It infers:
- Variable types from key names and value patterns
- Required flag (all set to true)
- Sensitive flag for SECRET/PASSWORD/KEY/TOKEN variables
- Example values from current values

name: incident-postmortem
description: Generate structured, blame-free incident postmortem reports from logs, timeline data, and incident metadata. Produces root cause analysis, impact assessment, timeline reconstruction, lessons learned, and action items. Supports log parsing (syslog, JSON, Apache/Nginx, Python tracebacks), timeline JSON input, blame-free language checking, and multiple output formats (markdown, HTML, JSON). Use when asked to create a postmortem, write an incident report, document an outage, generate a post-incident review, analyze incident timeline, check postmortem language for blame, create RCA (root cause analysis), or produce an after-action report. Triggers on "postmortem", "incident report", "outage report", "post-incident", "root cause analysis", "RCA", "after-action", "blameless review", "incident review".

# Incident Postmortem

Generate structured, blame-free incident postmortem reports with timeline reconstruction, log analysis, and action item tracking.

## Quick Start

```bash
# Create a postmortem from scratch (fills in template sections)
python3 scripts/generate_postmortem.py --title "Database outage" --severity P1

# Parse logs to auto-extract timeline events
python3 scripts/generate_postmortem.py --title "API latency" --log /var/log/app.log --since 2h

# Load a complete incident from JSON
python3 scripts/generate_postmortem.py --from incident.json --output html -o postmortem.html

# Combine logs + manual timeline
python3 scripts/generate_postmortem.py --title "Deploy failure" --log /var/log/deploy.log --timeline events.json

# Check existing document for blameful language
python3 scripts/generate_postmortem.py --check-blame existing-report.md
```

## Features

1. **Log parsing** — Auto-detects syslog, JSON, Apache/Nginx, Python tracebacks, Docker, generic timestamped formats. Extracts errors, warnings, and notable events into a timeline.
2. **Timeline reconstruction** — Merges log-extracted events with manual timeline JSON. Sorted chronologically with event type labels (detection, action, escalation, resolution).
3. **Blame-free language** — Built-in checker scans for blameful patterns and suggests alternatives. Use `--check-blame` on any document.
4. **Severity classification** — P0 (critical) through P3 (low) with appropriate descriptions.
5. **Multiple outputs** — Markdown (default), HTML (styled), JSON (structured).
6. **CI-friendly exit codes** — 0 (clean), 1 (errors found), 2 (critical severity).
7. **Template sections** — Summary, impact, timeline, root cause, detection, resolution, lessons learned, action items.

## Options

| Flag | Default | Description |
|------|---------|-------------|
| `--title` | required | Incident title |
| `--severity` | P2 | P0, P1, P2, or P3 |
| `--date` | today | Incident date |
| `--duration` | TBD | How long it lasted |
| `--summary` | — | Brief summary text |
| `--log` | — | Log file path (repeatable) |
| `--since` | all | Time filter for logs (1h, 24h, 7d) |
| `--timeline` | — | Timeline JSON file |
| `--from` | — | Load full incident from JSON |
| `--output` | markdown | Output format: markdown, html, json |
| `-o` | stdout | Output file path |
| `--check-blame` | — | Check file for blameful language |

## Workflow

### After an Incident

1. Gather logs: `--log /var/log/app.log --log /var/log/nginx/error.log --since 4h`
2. Generate draft: `python3 scripts/generate_postmortem.py --title "..." --severity P1 --log ... -o draft.md`
3. Fill in template sections (summary, root cause, impact, resolution)
4. Run blame check: `--check-blame draft.md`
5. Add action items and share

### From Structured Data

1. Create `incident.json` with full details (see `references/templates.md` for schema)
2. Generate: `--from incident.json --output html -o postmortem.html`

### Periodic Review

Use JSON output to track action item completion across multiple postmortems.

FILE:STATUS.md
# incident-postmortem — Status

**Status:** Ready
**Price:** $59
**Built:** 2026-03-30

## Features
- Log parsing (syslog, JSON, Apache/Nginx, Python tracebacks, Docker, generic)
- Timeline reconstruction from logs + JSON events
- Blame-free language checker with suggestions
- Severity classification (P0-P3)
- 3 output formats (markdown, HTML, JSON)
- CI-friendly exit codes
- Template sections: summary, impact, timeline, root cause, detection, resolution, lessons, actions

## Tested
- Basic generation (--title --severity)
- Full JSON incident file (--from)
- Log parsing with event extraction
- HTML output with styled template
- JSON structured output
- Blame language checker
- Multiple log formats

## Next Steps
- Publish to ClawHub after April 10

FILE:log.md
# incident-postmortem — Log

## 2026-03-30

### Done
- Built complete incident postmortem generator
- Script: `scripts/generate_postmortem.py` (~450 lines Python stdlib)
- Reference: `references/templates.md` — JSON schema, event types, blame-free guide
- Features: log parsing (8 formats), timeline merge, blame checker, P0-P3 severity, 3 output formats
- 18 error indicator patterns for event classification
- 4 blameful language patterns with suggestions
- Tested: basic generation, full JSON, log parsing, HTML/JSON output, blame checker
- Packaged to `dist/incident-postmortem.skill` ✅

### Decisions
- $59 pricing — mid-range, accessible for engineering teams
- Pure Python stdlib — no dependencies
- Blame-free language checker as standalone feature (--check-blame)
- Exit codes: 0 clean, 1 errors, 2 critical — CI-friendly

# Postmortem Templates & Guidelines

## Incident JSON Schema

Use `--from incident.json` to load a complete incident definition:

```json
{
  "title": "Database connection pool exhaustion",
  "severity": "P1",
  "date": "2026-03-28",
  "duration": "45 minutes",
  "status": "Resolved",
  "author": "oncall-team",
  "summary": "Primary database became unresponsive due to connection pool exhaustion caused by a leaked connection in the new payment service.",
  "impact": "All API requests returned 503 for 45 minutes. ~12,000 users affected. Estimated revenue impact: $8,500.",
  "root_cause": "The payment service v2.3.1 deployed at 14:20 introduced a code path that opened database connections without closing them on error. Under load, this exhausted the 100-connection pool within 15 minutes.",
  "detection": "PagerDuty alert fired at 14:35 when API error rate exceeded 50% threshold. Time to detect: 15 minutes.",
  "resolution": "1. Rolled back payment service to v2.3.0 at 14:50\n2. Manually cleared stale connections\n3. Database recovered at 15:05",
  "timeline": [
    {"time": "2026-03-28T14:20:00", "event": "Payment service v2.3.1 deployed", "type": "action"},
    {"time": "2026-03-28T14:35:00", "event": "API error rate alert fired", "type": "detection"},
    {"time": "2026-03-28T14:38:00", "event": "Oncall engineer acknowledged", "type": "action"},

    {"time": "2026-03-28T15:05:00", "event": "All services recovered", "type": "resolution"}
  ],
  "lessons_learned": [
    "Connection pool monitoring was not alerting on utilization, only on total failures",
    "Rollback process took 12 minutes — should be automated",
    "The leak was caught in code review but not flagged as blocking"
  ],
  "action_items": [
    {"action": "Add connection pool utilization alerts at 80% threshold", "owner": "Platform", "priority": "P1", "due": "2026-04-05", "status": "Open"},
    {"action": "Implement automated rollback on error rate spike", "owner": "SRE", "priority": "P1", "due": "2026-04-15", "status": "Open"},
    {"action": "Add integration test for connection cleanup on error paths", "owner": "Payments", "priority": "P2", "due": "2026-04-10", "status": "Open"}
  ]
}
```

## Timeline Event Types

| Type | Meaning | Example |
|------|---------|---------|
| `action` | Something someone did | "Deployed v2.3.1", "Restarted service" |
| `detection` | Issue was noticed | "Alert fired", "Customer reported" |
| `escalation` | Escalated to another team | "Paged database oncall" |
| `communication` | Status update sent | "Posted to #incidents", "Updated status page" |
| `resolution` | Issue resolved | "Service recovered", "Fix deployed" |

## Blame-Free Language Guide

### Principles

1. **Describe system conditions, not human failings** — "The monitoring gap allowed..." not "The engineer failed to..."
2. **Use passive voice for errors** — "The config was deployed without validation" not "They deployed without validating"
3. **Focus on process gaps** — "The review process did not catch..." not "The reviewer missed..."
4. **Assume competence** — People made the best decisions with the information available at the time

### Replacements

| Blameful | Blame-free |
|----------|-----------|
| "Engineer X caused the outage" | "The deployment triggered a failure in..." |
| "Human error" | "A process gap allowed..." |
| "Should have known" | "The system did not surface..." |
| "Failed to check" | "The check was not part of the process" |
| "Careless mistake" | "The existing safeguards did not prevent..." |
| "Forgot to" | "The runbook did not include..." |

### Use `--check-blame` to scan existing documents:

```bash
python3 scripts/generate_postmortem.py --check-blame existing-postmortem.md
```

FILE:scripts/generate_postmortem.py
#!/usr/bin/env python3

description: Scan project dependencies for license compatibility issues, GPL contamination, and compliance violations. Supports npm, pip, Go, Rust, and Ruby ecosystems. Use when asked to audit licenses, check license compliance, find GPL contamination, verify dependency licensing, generate license reports, or ensure open-source compliance before shipping. Also use for CI/CD license gates.
---

# Dependency License Audit

Scan project dependencies for license compatibility issues across multiple ecosystems.

## Quick Start

```bash
# Basic scan (permissive policy)
python3 scripts/license_audit.py /path/to/project

# Strict enterprise scan with CI exit codes
python3 scripts/license_audit.py /path/to/project --policy permissive --ci --format markdown

# Allow weak copyleft (LGPL, MPL)
python3 scripts/license_audit.py /path/to/project --policy weak-copyleft

# Include transitive deps (npm)
python3 scripts/license_audit.py /path/to/project --include-transitive

# JSON output for tooling
python3 scripts/license_audit.py /path/to/project --format json
```

## Supported Ecosystems

| Ecosystem | Files Parsed | License Source |
|-----------|-------------|----------------|
| npm | package.json, package-lock.json, node_modules/*/package.json | Package metadata |
| pip | requirements.txt, Pipfile, pyproject.toml | Installed package metadata |
| Go | go.mod | Manual/UNKNOWN (no local metadata) |
| Rust | Cargo.toml | Manual/UNKNOWN (no local metadata) |
| Ruby | Gemfile | Manual/UNKNOWN (no local metadata) |

npm and pip auto-detect licenses from installed packages. Go/Rust/Ruby report UNKNOWN unless packages are installed — review manually.

## Policies

| Policy | Allows | Use When |
|--------|--------|----------|
| `permissive` (default) | MIT, Apache-2.0, BSD, ISC, etc. | Proprietary/commercial projects |
| `weak-copyleft` | + LGPL, MPL, EPL | Library consumers (dynamic linking) |
| `any-open` | All OSI-approved | Open-source projects |
| `custom` | User-defined | Enterprise with specific requirements |

For custom policy setup, see [references/custom-policy.md](references/custom-policy.md).

## Output Formats

- `text` — Human-readable terminal output (default)
- `json` — Machine-readable for CI pipelines and tooling
- `markdown` — Report with tables, suitable for PRs or documentation

## CI Exit Codes

With `--ci` flag:
- `0` — No issues
- `1` — Warnings only (unknown licenses)
- `2` — Policy violations found

## License Classifications

The scanner classifies licenses into categories:

- **permissive** — MIT, Apache-2.0, BSD, ISC, Unlicense, CC0, etc.
- **weak-copyleft** — LGPL, MPL, EPL, CDDL (modifications must be shared, but linking is OK)
- **strong-copyleft** — GPL, AGPL, SSPL (derivative works inherit the license)
- **proprietary** — UNLICENSED or commercial indicators
- **unknown** — Not recognized; manual review needed

SPDX expressions (`MIT OR Apache-2.0`, `MIT AND BSD-3-Clause`) are evaluated: OR picks most permissive, AND picks most restrictive.

## Workflow

1. Run audit against project directory
2. Review violations and warnings in output
3. For each violation, follow the recommendations provided
4. Optionally create `.license-policy.json` for custom rules
5. Add `--ci` flag to CI pipeline for automated enforcement

FILE:STATUS.md
# dependency-license-audit — Status

**Price:** $69
**Status:** Ready
**Created:** 2026-03-29

## Features
- 5 ecosystem support: npm, pip, Go, Rust, Ruby
- 4 built-in policies: permissive, weak-copyleft, any-open, custom
- Custom policy via .license-policy.json (allowed/blocked lists + exceptions)
- 80+ license aliases → SPDX normalization
- SPDX expression support (OR/AND evaluation)
- 3 output formats: text, JSON, markdown
- CI-friendly exit codes (0/1/2)
- Transitive dependency scanning (npm)
- Actionable recommendations per violation type

## Tested Against
- OpenClaw npm package (70 deps, correctly classified 48 permissive)
- Multi-ecosystem fixture (npm + pip + go + cargo + gem)
- CI exit codes verified
- Custom policy with exceptions verified
- SPDX parenthesized expressions verified

## Next Steps
- Publish after April 10 (GitHub 14-day wait)

FILE:log.md
# dependency-license-audit — Log

## 2026-03-29

### Done
- Built complete license audit scanner (pure Python stdlib)
- 5 ecosystems: npm (package.json + lock + node_modules), pip (requirements.txt + Pipfile + pyproject.toml), Go (go.mod), Rust (Cargo.toml), Ruby (Gemfile)
- 80+ license aliases mapped to SPDX identifiers
- License classification: permissive, weak-copyleft, strong-copyleft, proprietary, unknown
- SPDX expression evaluation (OR → most permissive, AND → most restrictive)
- 4 policies: permissive, weak-copyleft, any-open, custom (.license-policy.json)
- 3 output formats: text, JSON, markdown
- CI exit codes: 0 clean, 1 warnings, 2 violations
- Actionable recommendations per license classification
- Fixed: SPDX parenthesized expressions like `(MIT OR GPL-3.0-or-later)`
- Tested against real OpenClaw package (70 deps) + multi-ecosystem fixture
- Packaged to dist/dependency-license-audit.skill ✅

### Decisions
- $69 pricing — matches log-analyzer, addresses enterprise compliance need
- Pure Python stdlib — no deps, maximum compatibility
- UNKNOWN = warning (not error) — less noise for Go/Rust/Ruby where local metadata unavailable
- Custom policy supports exceptions list — critical for enterprise adoption

FILE:references/custom-policy.md
# Custom License Policy

Create `.license-policy.json` in the project root to define custom rules.

## Schema

```json
{
  "allowed_classifications": ["permissive", "weak-copyleft"],
  "allowed_licenses": ["MIT", "Apache-2.0", "LGPL-2.1-only"],
  "blocked_licenses": ["AGPL-3.0-only", "SSPL-1.0"],
  "exceptions": ["some-internal-package"]
}
```

## Fields

| Field | Type | Description |
|-------|------|-------------|
| `allowed_classifications` | string[] | License categories: `permissive`, `weak-copyleft`, `strong-copyleft` |
| `allowed_licenses` | string[] | Specific SPDX IDs to allow regardless of classification |
| `blocked_licenses` | string[] | Specific SPDX IDs to always reject |
| `exceptions` | string[] | Package names to skip (pre-approved) |

## Examples

### Permissive only, with one exception
```json
{
  "allowed_classifications": ["permissive"],
  "exceptions": ["internal-gpl-lib"]
}
```

### Enterprise (no AGPL/SSPL)
```json
{
  "allowed_classifications": ["permissive", "weak-copyleft", "strong-copyleft"],
  "blocked_licenses": ["AGPL-3.0-only", "AGPL-3.0-or-later", "SSPL-1.0"]
}
```

## CI Integration

```bash
# GitHub Actions
- name: License audit
  run: python3 scripts/license_audit.py . --policy custom --ci

# GitLab CI
license-audit:
  script: python3 scripts/license_audit.py . --policy custom --ci --format json > license-report.json
  artifacts:
    paths: [license-report.json]
```

# Secrets Audit

Scan any project directory for exposed secrets, hardcoded credentials, and sensitive data leaks. Produces a severity-ranked report with remediation steps.

## Quick Start

```bash
# Full project scan
python3 scripts/scan_secrets.py /path/to/project

# Scan with git history check
python3 scripts/scan_secrets.py /path/to/project --git-history

# Scan specific file types only
python3 scripts/scan_secrets.py /path/to/project --extensions .py,.js,.ts,.env,.yml,.json

# JSON output for CI integration
python3 scripts/scan_secrets.py /path/to/project --format json
```

## What Gets Detected

### High Severity
- API keys (AWS, GCP, Azure, OpenAI, Stripe, etc.)
- Database connection strings with credentials
- Private keys (RSA, SSH, PGP)
- OAuth tokens and refresh tokens
- JWT secrets and signing keys
- Password fields with literal values

### Medium Severity
- `.env` files with populated secrets
- Config files with credentials (database.yml, settings.py, etc.)
- Hardcoded URLs with embedded auth (user:pass@host)
- Webhook URLs with tokens
- Generic high-entropy strings in assignment context

### Low Severity
- TODO/FIXME comments mentioning secrets
- Placeholder credentials (admin/admin, test/test)
- Example API keys in documentation
- Commented-out credentials

### Ignored (False Positive Reduction)
- Lock files (package-lock.json, yarn.lock, etc.)
- Binary files
- Minified JS/CSS
- Test fixtures clearly marked as fake
- node_modules, .git, vendor directories

## Scan Output

The scanner produces a structured report:

```
=== Secrets Audit Report ===
Project: /path/to/project
Scanned: 247 files | Skipped: 1,203 files
Time: 2.3s

--- HIGH SEVERITY (3 findings) ---

[H1] AWS Access Key ID
  File: src/config/aws.js:14
  Match: AKIA...EXAMPLE
  Context: const accessKey = "AKIA..."
  Fix: Move to environment variable AWS_ACCESS_KEY_ID

[H2] Database Password
  File: config/database.yml:8
  Match: password: "pr0duction_p@ss"
  Fix: Use DATABASE_URL env var or secrets manager

--- MEDIUM SEVERITY (5 findings) ---
...

--- SUMMARY ---
High: 3 | Medium: 5 | Low: 2 | Total: 10
Recommendation: Rotate all HIGH severity credentials immediately
```

## Workflow

### 1. Scan

Run `scripts/scan_secrets.py` against the target directory. The script:
- Recursively walks the directory tree
- Skips binary files, lock files, and dependency directories
- Applies 40+ regex patterns from `references/secret-patterns.md`
- Calculates entropy for potential secrets
- Deduplicates findings

### 2. Review

Present findings grouped by severity. For each finding:
- Show the file, line number, and surrounding context
- Explain what type of secret was found
- Assess whether it's a real secret or false positive

### 3. Remediate

For each confirmed finding, provide specific remediation:
- Which environment variable to use
- How to add to `.gitignore`
- Whether the secret needs rotation (if committed to git)
- Example code showing the fix

### 4. Verify

After remediation:
- Re-run the scan to confirm fixes
- Check git history if secrets were ever committed
- Recommend adding pre-commit hooks to prevent future leaks

## Git History Scanning

When `--git-history` flag is used, the script also checks:
- Deleted files that contained secrets
- Previous versions of files that had secrets removed
- Commits with "secret", "password", "key" in messages

Important: if a secret was ever committed to git, it must be rotated even if later removed — it exists in git history.

## CI Integration

The script returns exit codes for CI pipelines:
- `0` — No findings
- `1` — Low/medium findings only
- `2` — High severity findings (should block deployment)

JSON output (`--format json`) can be parsed by CI tools for automated reporting.

## Pre-commit Hook Setup

After an audit, recommend setting up a pre-commit hook. See `references/prevention-guide.md` for hook installation and configuration.

FILE:STATUS.md
# secrets-audit — Status

**Status:** Ready
**Price:** $59
**Created:** 2026-03-27

## What It Does
Scans project directories for exposed secrets, API keys, tokens, and credentials. 40+ regex patterns covering AWS, GCP, Azure, OpenAI, Stripe, GitHub, databases, and more. Reports with severity ranking and remediation steps.

## Components
- `SKILL.md` — Main skill instructions with workflow
- `scripts/scan_secrets.py` — Core scanner (40+ patterns, entropy analysis, CI exit codes)
- `references/secret-patterns.md` — Extended pattern reference with remediation guide
- `references/prevention-guide.md` — Pre-commit hooks and .gitignore setup

## Testing
- [x] Scanner tested with sample project containing planted secrets
- [x] Detected AWS keys, DB URLs, Stripe keys, env passwords correctly
- [x] Text output format works with severity grouping
- [x] JSON output format works for CI integration
- [x] Exit codes: 0 (clean), 1 (medium), 2 (high) — working
- [x] False positive reduction via entropy filtering
- [x] Script executable

## Next Steps
- Package to .skill file
- Publish to ClawHub

FILE:log.md
# secrets-audit — Log

## 2026-03-27

### Done
- Initialized skill with scripts, references directories
- Wrote SKILL.md with quick start, detection categories, workflow, CI integration
- Built `scripts/scan_secrets.py` — 40+ patterns covering AWS/GCP/Azure/OpenAI/Stripe/GitHub/databases/webhooks/Telegram/etc.
- Includes Shannon entropy calculation for false positive reduction
- Git history scanning (deleted files, suspicious commit messages)
- CI-friendly exit codes (0/1/2) and JSON output format
- Created `references/secret-patterns.md` — extended pattern reference with remediation
- Created `references/prevention-guide.md` — pre-commit hooks, .gitignore, secrets managers
- Tested with sample project — all planted secrets detected correctly
- Created STATUS.md

### Decisions
- Priced at $59 — dev-focused, lower barrier to entry
- Pure Python stdlib — no external dependencies needed
- Entropy threshold at 2.5 bits — good balance of sensitivity vs false positives
- Skip directories/files aggressively to keep scan fast

### Blockers
- None — ready to package

git secrets --add 'sk-proj-[A-Za-z0-9_-]{40,}'
```

### Option 2: pre-commit framework

```yaml
# .pre-commit-config.yaml
repos:
  - repo: https://github.com/Yelp/detect-secrets
    rev: v1.4.0
    hooks:
      - id: detect-secrets
        args: ['--baseline', '.secrets.baseline']
```

```bash
pip install pre-commit
pre-commit install
```

### Option 3: Simple bash hook

```bash
#!/bin/bash
# .git/hooks/pre-commit

PATTERNS=(
  'AKIA[0-9A-Z]{16}'
  'sk_live_'
  'sk-proj-'
  'ghp_[A-Za-z0-9_]{36}'
  '-----BEGIN.*PRIVATE KEY-----'
)

for pattern in "PATTERNS[@]"; do
  if git diff --cached --diff-filter=ACM | grep -qE "$pattern"; then
    echo "ERROR: Potential secret detected matching pattern: $pattern"
    echo "Use 'git diff --cached' to review."
    exit 1
  fi
done
```

## .gitignore Essentials

Add these to every project's `.gitignore`:

```
# Environment files
.env
.env.local
.env.*.local
.env.production
.env.staging

# Key files
*.pem
*.key
*.p12
*.pfx
id_rsa*
*.jks

# Credentials
credentials.json
service-account*.json
*-credentials.json
```

## Remediation Guide

### For Each Severity Level

**HIGH — Immediate action required:**
1. Rotate the credential immediately
2. Check access logs for unauthorized use
3. Move to environment variable or secrets manager
4. Add file pattern to `.gitignore`
5. If committed to git: use `git filter-branch` or BFG Repo-Cleaner

**MEDIUM — Review and fix:**
1. Verify if the credential is real or placeholder
2. Move to environment variable if real
3. Consider using a secrets manager (Vault, AWS Secrets Manager, etc.)

**LOW — Track and plan:**
1. Replace placeholder credentials with proper env var references
2. Update documentation to use example placeholders (e.g., `YOUR_API_KEY_HERE`)
3. Add pre-commit hooks to prevent future leaks

### Environment Variable Best Practices
- Use `.env` files for local development (add to `.gitignore`)
- Use secrets manager for production
- Never set defaults for secret env vars in code
- Use `required: true` validation for secret config values

# Client Report Generator

Generate polished, client-ready reports from raw data. Feed it CSV, JSON, analytics exports, or plain text metrics — get back a professional report formatted for delivery.

## Workflow

### 1. Ingest Data

Determine input type and extract data:

- **CSV/TSV file** → Read and parse into structured data
- **JSON file/API response** → Parse and extract key metrics
- **Pasted text/numbers** → Parse inline data
- **URL (dashboard/analytics)** → Use `web_fetch` to extract visible data
- **Multiple sources** → Combine into unified dataset

Run `scripts/parse_data.py` to normalize any structured input:

```bash
python3 scripts/parse_data.py <input-file> [--format csv|json|auto]
```

Output: normalized JSON with detected metrics, dimensions, and time ranges.

### 2. Analyze & Summarize

Before generating the report, analyze the data:

1. **Key metrics** — Identify top-line numbers (revenue, growth, conversions, etc.)
2. **Trends** — Period-over-period changes (up/down/flat + percentage)
3. **Highlights** — Best-performing items, records, milestones
4. **Concerns** — Underperforming areas, declining trends, anomalies
5. **Context** — Infer reporting period, industry, and audience from data

### 3. Select Report Template

Choose based on user request or data type. See `references/report-templates.md` for detailed templates.

| Template | Best For |
|----------|----------|
| **Performance Review** | Monthly/weekly KPI summaries |
| **Campaign Report** | Marketing campaign results |
| **Project Status** | Development/project progress updates |
| **Analytics Summary** | Website/app analytics overview |
| **Custom** | User-specified structure |

### 4. Generate Report

Structure every report with:

```
# [Report Title]
**Period:** [date range]  |  **Prepared for:** [client name]  |  **Date:** [today]

## Executive Summary
[2-3 sentences: what happened, key takeaway, recommendation]

## Key Metrics
| Metric | Current | Previous | Change |
|--------|---------|----------|--------|
| ...    | ...     | ...      | +X%    |

## [Detailed Sections — template-specific]

## Highlights & Wins
- ...

## Areas for Improvement
- ...

## Recommendations & Next Steps
1. ...
```

### 5. Format Output

**Default output:** Markdown (clean, portable, renders in most tools)

**Other formats on request:**
- **HTML** → Run `scripts/report_to_html.py` for styled HTML with inline CSS
- **Plain text** → Stripped formatting for email body
- **Structured data** → JSON summary of all metrics and analysis

```bash
python3 scripts/report_to_html.py <report.md> [--template default|minimal|branded]
```

## Customization Options

Users can specify:
- **Client name** — appears in header and throughout
- **Reporting period** — "last week", "March 2026", "Q1 2026"
- **Tone** — professional (default), friendly, executive-brief
- **Sections** — include/exclude specific sections
- **Branding** — company name, colors (for HTML output)
- **Comparison** — vs previous period, vs target/goal, vs benchmark
- **Charts** — include ASCII/text charts for key metrics (when data supports it)
- **Language** — generate in specified language

## Data Handling

- Automatically detect metric types (currency, percentages, counts, rates)
- Format numbers appropriately (commas, decimal places, currency symbols)
- Calculate period-over-period changes when historical data is available
- Flag statistical anomalies or significant changes (>20% swings)
- Round appropriately for audience (executives get rounded numbers, analysts get precision)

## Tips

- For executive audiences: lead with the bottom line, keep it to 1 page equivalent
- For marketing reports: emphasize ROI and conversion metrics
- For project status: focus on timeline, blockers, and deliverables
- When data is incomplete: note gaps clearly, don't fabricate numbers
- Include "So what?" after every metric — explain why the number matters

FILE:STATUS.md
# client-report-generator — Status

**Status:** Ready
**Price:** $79
**Created:** 2026-03-27

## What It Does
Generates professional client-facing reports from CSV, JSON, or raw data. Includes data parsing, metric detection, trend analysis, and HTML export with multiple themes.

## Components
- `SKILL.md` — Main skill instructions with workflow
- `scripts/parse_data.py` — Data parser (CSV/TSV/JSON → normalized metrics)
- `scripts/report_to_html.py` — Markdown → styled HTML converter (3 themes)
- `references/report-templates.md` — 4 detailed report templates

## Testing
- [x] parse_data.py tested with CSV data (currency, percentage, count detection works)
- [x] parse_data.py tested with JSON array data
- [x] report_to_html.py tested with sample report (default theme)
- [x] report_to_html.py tested with branded theme
- [x] All scripts executable

## Next Steps
- Package to .skill file
- Publish to ClawHub

FILE:log.md
# client-report-generator — Log

## 2026-03-27

### Done
- Initialized skill with scripts, references, assets directories
- Wrote SKILL.md with comprehensive workflow (ingest → analyze → template → generate → format)
- Built `scripts/parse_data.py` — auto-detects CSV/TSV/JSON, classifies metric types (currency, percentage, count, rate, text), computes stats
- Built `scripts/report_to_html.py` — converts Markdown reports to styled HTML with inline CSS, 3 themes (default, minimal, branded)
- Created `references/report-templates.md` with 4 detailed templates: Performance Review, Campaign Report, Project Status, Analytics Summary
- Tested all scripts with sample data — all working
- Removed empty assets/ directory (not needed)
- Created STATUS.md

### Decisions
- Priced at $79 — higher than basic tools ($49) because it solves an expensive recurring problem for agencies
- Focused on practical report types that agencies actually send (not academic/internal)
- 3 HTML themes to cover different brand aesthetics
- No external dependencies — pure Python stdlib for maximum compatibility

### Blockers
- None — ready to package

# Git Release Notes

Generate formatted release notes from git commit history. Analyzes commits between any two refs (tags, branches, SHAs) and produces categorized, human-readable release notes.

## Quick Usage

### Generate Notes Between Tags
```bash
scripts/gather_commits.sh v1.2.0 v1.3.0
```
Then format the JSON output into release notes using the formatting rules below.

### Generate Notes Since Last Tag
```bash
scripts/gather_commits.sh $(git describe --tags --abbrev=0) HEAD
```

### Generate Notes Between Branches
```bash
scripts/gather_commits.sh main release/2.0
```

## Workflow

### 1. Gather Commits

Run `scripts/gather_commits.sh <from_ref> <to_ref>` to get structured commit data (JSON array).

If no refs provided, ask user for:
- The starting point (tag, branch, or SHA)
- The ending point (default: HEAD)

### 2. Categorize Commits

Group commits by type using conventional commit prefixes and content analysis:

| Category | Prefixes / Signals | Emoji |
|----------|-------------------|-------|
| Breaking Changes | `BREAKING CHANGE:`, `!:` in subject | 💥 |
| Features | `feat:`, `feature:`, `add:` | ✨ |
| Bug Fixes | `fix:`, `bugfix:`, `hotfix:` | 🐛 |
| Performance | `perf:` | ⚡ |
| Documentation | `docs:`, `doc:` | 📚 |
| Refactoring | `refactor:` | ♻️ |
| Testing | `test:`, `tests:` | 🧪 |
| CI/Build | `ci:`, `build:`, `chore:` | 🔧 |
| Dependencies | `deps:`, `dep:`, "bump", "upgrade" in subject | 📦 |
| Other | Anything else | 📝 |

If commits don't follow conventional commits, analyze the commit message content to infer categories.

### 3. Format Release Notes

Default format (GitHub Release style):

```markdown
# v1.3.0

> Released on 2026-03-26 | 47 commits | 5 contributors

## 💥 Breaking Changes
- Remove deprecated `legacy_auth` endpoint (#234)

## ✨ Features
- Add dark mode support (#220)
- Implement batch export for CSV/JSON (#215)

## 🐛 Bug Fixes
- Fix race condition in queue processor (#228)
- Correct timezone handling for UTC offset (#225)

## ⚡ Performance
- Optimize database queries for dashboard load (#222)

## 📦 Dependencies
- Bump express from 4.18 to 4.21

## 🔧 Other
- Update CI pipeline for Node 22

**Full Changelog:** v1.2.0...v1.3.0
```

### 4. Alternative Formats

**Compact (for small releases):**
```
v1.3.0 — Dark mode, batch export, 5 bug fixes. Breaking: removed legacy_auth.
```

**Keep a Changelog (keepachangelog.com):**
```markdown
## [1.3.0] - 2026-03-26
### Added
- Dark mode support
### Changed
- Optimized dashboard queries
### Removed
- Deprecated legacy_auth endpoint
### Fixed
- Race condition in queue processor
```

**Slack/Discord announcement:**
```
🚀 **v1.3.0 is out!**

Highlights:
→ Dark mode support
→ Batch CSV/JSON export
→ 5 bug fixes

⚠️ Breaking: `legacy_auth` endpoint removed — migrate to `/v2/auth`
```

## Customization

Users can specify:
- **Format** — github (default), compact, keepachangelog, slack
- **Include/exclude categories** — "skip docs and chore commits"
- **Group by** — category (default), author, scope
- **PR links** — auto-detect GitHub PR numbers (#NNN)
- **Contributors** — list contributors at the bottom
- **Scope filter** — only include commits touching certain paths

## Scripts

- `scripts/gather_commits.sh <from> <to>` — Outputs JSON array of commits with hash, author, date, subject, body

FILE:STATUS.md
# Git Release Notes — Status

**Status:** Built, tested, validated, packaged. Ready for publishing.
**Version:** 1.0.0
**Price:** $49

## Next Steps
- [ ] Publish to ClawHub
- [ ] Add support for monorepo scope filtering
- [ ] Add "auto-detect" mode (find latest two tags automatically)

FILE:log.md
# Git Release Notes — Log

## 2026-03-26

### Done
- Created skill with init_skill.py (scripts resource)
- Wrote SKILL.md: workflow, commit categorization table, 4 output formats (GitHub, compact, keepachangelog, Slack)
- Wrote scripts/gather_commits.sh — extracts commits as JSON with hash, author, date, subject, body
- Tested against Express.js repo (8 commits) — clean JSON output with conventional commit subjects
- Validated and packaged to dist/git-release-notes.skill

### Decisions
- Bash + Python hybrid script: bash for git commands, Python for JSON serialization
- Conventional commit prefix recognition for categorization
- 4 format options: GitHub release, compact, Keep a Changelog, Slack/Discord
- Agent does the categorization and formatting (not the script) — more flexible
- Price: $49 (dev tool, straightforward value prop)

name: site-health-monitor
description: Monitor websites for uptime, SSL certificate expiry, response time, HTTP errors, and content changes. Generate health reports and send alerts when issues are detected. Use when asked to monitor a website, check site health, track uptime, verify SSL certificates, detect downtime, set up website monitoring, check if a site is up, or audit website performance. Triggers on "monitor site", "check uptime", "SSL expiry", "is my site up", "website health", "site status", "monitor URL", "check website".

# Site Health Monitor

Monitor one or more websites for health issues. Detect downtime, expiring SSL certs, slow responses, and content changes — then report or alert.

## Quick Check (Single URL)

When user asks to check a single URL right now:

1. Run `scripts/check_site.sh <url>`
2. Parse the JSON output
3. Present a formatted health report

## Monitored Sites Config

For ongoing monitoring, maintain a config at user's chosen location (default: `~/.openclaw/workspace/site-monitor.json`):

```json
{
  "sites": [
    {
      "url": "https://example.com",
      "name": "Main Site",
      "checks": ["uptime", "ssl", "response_time", "content"],
      "alert_threshold_ms": 3000,
      "ssl_warn_days": 14,
      "content_selector": "title"
    }
  ],
  "defaults": {
    "checks": ["uptime", "ssl", "response_time"],
    "alert_threshold_ms": 5000,
    "ssl_warn_days": 30
  }
}
```

## Health Checks

### 1. Uptime
- HTTP GET to URL
- **Pass:** 2xx/3xx status
- **Warning:** 4xx status
- **Fail:** 5xx, connection refused, timeout (>10s)

### 2. SSL Certificate
- Run `scripts/check_ssl.sh <domain>`
- **Pass:** Valid, >30 days to expiry
- **Warning:** <30 days to expiry (configurable)
- **Fail:** Expired, self-signed, or missing

### 3. Response Time
- Measure TTFB + transfer via `scripts/check_site.sh`
- **Pass:** Under threshold (default 5000ms)
- **Warning:** 1-2x threshold
- **Fail:** >2x threshold or timeout

### 4. Content Changes (Planned)
- Fetch page, extract text, hash it
- Compare against stored hash
- Report if content changed since last check
- *Note: This feature is planned for v1.1*

## Reports

### Single Site
```
## 🟢 example.com — Healthy
| Check         | Status | Detail                    |
|---------------|--------|---------------------------|
| Uptime        | ✅ UP  | 200 OK (143ms)            |
| SSL           | ✅ OK  | Expires in 87 days        |
| Response Time | ✅ OK  | 342ms (threshold: 5000ms) |
| Content       | — Same | No changes detected       |
```

### Multi-Site Summary
```
## Site Health — 2026-03-26
| Site       | Status | Issues         |
|------------|--------|----------------|
| example.com| 🟢 OK | —              |
| api.foo.io | 🟡 WARN| SSL: 12 days  |
| shop.bar   | 🔴 DOWN| 503 error     |
```

### Alerts
Alert when: site DOWN, SSL within warning window, response >2x threshold, 2+ consecutive failures.

Format: `⚠️ [site] — [issue]. [detail]. Checked at [time].`

## Scheduled Monitoring

Suggest cron job for recurring checks (30-60 min interval for production). Store last 100 results per site in `~/.openclaw/workspace/.site-monitor-history.json`.

## Scripts

- `scripts/check_site.sh <url>` — HTTP health check, outputs JSON (status, timing, headers)
- `scripts/check_ssl.sh <domain>` — SSL cert check, outputs JSON (issuer, expiry, days remaining)

FILE:STATUS.md
# Site Health Monitor — Status

**Status:** Built, tested, validated, packaged. Ready for publishing.
**Version:** 1.0.0
**Price:** $49

## Next Steps
- [ ] Publish to ClawHub
- [ ] Add content change detection script
- [ ] Create monitoring history/dashboard feature for v1.1

FILE:log.md
# Site Health Monitor — Log

## 2026-03-26

### Done
- Created skill with init_skill.py (scripts + references resources)
- Wrote SKILL.md: quick check, config, 4 health check types, report formats, alerts
- Wrote scripts/check_site.sh — HTTP health check with timing (curl JSON output)
- Wrote scripts/check_ssl.sh — SSL cert check with days-remaining calculation
- Tested both scripts: google.com (success), non-existent domain (graceful error)
- Validated and packaged to dist/site-health-monitor.skill

### Decisions
- Bash scripts over Python — lighter dependency, works everywhere
- curl's `%{json}` output format for structured timing data
- Graceful error handling: always outputs valid JSON even on failure
- Config file approach for multi-site monitoring
- Price: $49 (includes scripts, good entry-level price)

- Content change detection not yet scripted (v1.1)
