--- name: site-reliability-engineer description: Docusaurus build health validation and deployment safety for Claude Skills showcase. Pre-commit MDX validation (Liquid syntax, angle brackets, prop mismatches), pre-build link checking, post-build health reports. Activate on 'build errors', 'commit hooks', 'deployment safety', 'site health', 'MDX validation'. NOT for general DevOps (use deployment-engineer), Kubernetes/cloud infrastructure (use kubernetes-architect), runtime monitoring (use observability-engineer), or non-Docusaurus projects. allowed-tools: Read,Write,Edit,Bash,Grep,Glob metadata: category: DevOps & Site Reliability pairs-with: - skill: devops-automator reason: CI/CD for site deployments - skill: skill-documentarian reason: Maintain skill documentation quality tags: - docusaurus - build-health - mdx - validation - deployment --- # Site Reliability Engineer Expert in Docusaurus build health, MDX validation, and deployment safety for the Claude Skills showcase website. Prevents common build failures through pre-commit validation and automated health checks. ## When to Use **Use for:** - Pre-commit validation of markdown/MDX files - Catching Liquid template syntax errors - Validating SkillHeader component props - Checking for missing hero images/ZIP files - Pre-build link validation - Post-build health reports - Diagnosing Docusaurus build failures **Do NOT use for:** - General DevOps (use deployment-engineer) - Kubernetes/cloud infrastructure (use kubernetes-architect) - Runtime monitoring/alerting (use observability-engineer) - Database migrations (use database-migrations agents) - Security scanning (use security-auditor) ## Core Problem Domain ### The 5 Recurring Anti-Patterns | # | Problem | Symptom | Fix | |---|---------|---------|-----| | 1 | Liquid syntax in examples | Liquid templates break MDX | Wrap in backtick expression | | 2 | Unescaped angle brackets | `&lt;70` parsed as HTML | Use `&lt;70` | | 3 | Wrong SkillHeader props | SSG build failure | Use `fileName` not `skillId` | | 4 | Missing critical files | Skill invisible on site | Add to `skills.ts` | | 5 | Cache corruption | Phantom errors | Clear `.docusaurus`, `build` | ## Quick Start ### Install Hooks (One-Time) ```bash npm run install-hooks ``` ### Manual Validation ```bash npm run validate:liquid # Liquid syntax npm run validate:brackets # Angle brackets npm run validate:props # SkillHeader props npm run validate:all # All checks ``` ### Clear Cache (When Stuck) ```bash rm -rf .docusaurus build node_modules/.cache npm run build ``` ## Pre-Commit Validation The pre-commit hook automatically: 1. **Liquid syntax** - Scans for double-brace templates outside code blocks 2. **Angle brackets** - Finds `<digit` patterns 3. **SkillHeader props** - Validates component usage 4. **Required files** - Checks hero images, ZIPs exist **Speed**: Under 5 seconds for typical commits ## Expert vs Novice Approach | Novice | Expert | |--------|--------| | Runs full build to check | Pre-commit catches 90% in 5 seconds | | Manual cache clearing | Auto-detect cache issues | | Ignores warnings | Zero-tolerance for broken links | | Simple regex validation | Context-aware (skips code blocks) | ## Anti-Patterns ### Anti-Pattern: Full Build for Validation **What it looks like**: `npm run build` to check for errors **Why wrong**: Minutes vs seconds, slow feedback **Instead**: `npm run validate:all` (under 30 seconds) ### Anti-Pattern: Ignoring Build Warnings **What it looks like**: "Build succeeded, ship it!" (ignoring warnings) **Why wrong**: Broken links = poor UX, tech debt **Instead**: Post-build validation fails on warnings ### Anti-Pattern: Naive Regex Validation **What it looks like**: `/{{.*?}}/` (matches in code blocks too) **Why wrong**: False positives in code examples **Instead**: Track code block state, skip protected regions ## Scripts (in `scripts/` folder) | Script | Purpose | |--------|---------| | `validate-liquid.js` | Detect unescaped Liquid syntax | | `validate-brackets.js` | Detect unescaped angle brackets | | `validate-skill-props.js` | Validate SkillHeader component | ## Troubleshooting Quick Reference | Issue | Diagnosis | Fix | |-------|-----------|-----| | Hook not running | `ls -la .git/hooks/pre-commit` | `chmod +x` or reinstall | | False positives | Pattern in code block | Check ``` markers | | Slow validation | `time npm run validate:all` | Optimize glob patterns | ## Success Metrics After installing hooks: - **Build failure rate**: 15% → under 2% - **Time to diagnose errors**: 10 min → under 1 min - **Validation speed**: Under 30 seconds ## Reference Files - `references/validation-logic.md` - Context-aware detection patterns - `references/ci-cd-integration.md` - GitHub Actions, health reports - `scripts/` - Working validation scripts --- **Prevents**: Liquid errors | Angle bracket failures | Prop mismatches | Missing assets | Broken links **Use with**: skill-documentarian (sync) | docusaurus-expert (advanced config)
