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.

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	`<70` parsed as HTML	Use `<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:

Liquid syntax - Scans for double-brace templates outside code blocks
Angle brackets - Finds
```
<digit
```
patterns
SkillHeader props - Validates component usage
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
