Skills by Quality

Quick overview grouped by rating to identify improvement priorities:

⭐⭐⭐⭐⭐ Exemplary (5 skills)

Deep insights + original approaches, comprehensive content:

Skill	Category	What makes it exemplary
gh	git-tools	Deep mental model, original workflow patterns, exemplary progressive disclosure
mcp-builder	claude-code-meta	Deep best practices, includes working evaluation tools
cli-skill-creator	claude-code-meta	Highly original meta-skill, systematic CLI introspection approach
dignified-python	coding-standards	Deep LBYL philosophy, original error-handling approach
kaizen	coding-standards	Deep principles with original adaptation to code

⭐⭐⭐⭐ High Quality (8 skills)

Good depth, well-structured, production ready:

Skill	Category	Notes
dignified-bash	coding-standards	Well-structured but standard bash practices
linux-sysadmin	devops	Useful practices, standard content
metabase-swiss-knife	databases	Full CLI with backup/restore, zero dependencies
doc-coauthoring	docs	Good workflow but not particularly deep
claude-md-writer	claude-code-meta	Good compilation of best practices
meeting-insights-analyzer	productivity	Original approach to meeting analysis
vercel-react-best-practices	web-dev	Great structure but just packages Vercel rules

⭐⭐⭐ Solid but Shallow (5 skills)

⚠️ Candidates for replacement/deepening — Complete but lacking depth or originality:

Skill	Category	Why shallow/standard	Replacement strategy
changelog-generator	git-tools	Just a workflow, not deep	Find deeper changelog philosophy/patterns
git-workflow-manager	git-tools	Basic conventional commits reference	Find advanced git workflow patterns
opencode-config	claude-code-meta	Just config reference, shallow	Find deeper OpenCode configuration insights
claude-md-redirect	claude-code-meta	Utility, very shallow	Consider removing or expanding
readme-generator	docs	Just process, shallow content	Find README philosophy/patterns beyond basics

⭐⭐ Incomplete (3 skills)

🚨 Priority for improvement — Functional but missing critical content:

Skill	Category	What's missing	Search for
software-architecture	coding-standards	Needs examples, library guide	Code pattern examples, library-first guides
web-artifacts-builder	web-dev	Needs troubleshooting guide, component patterns, examples	React artifact patterns, debugging guides
web-design-guidelines	web-dev	Needs expansion (176→1500 words), sample output examples	UI/UX guidelines, review examples

---

Quality Rating

Quality is rated on four dimensions:

1. Structure — Progressive disclosure, references/, examples/, clear organization
2. Completeness — All sections present, no missing content
3. Depth — Insights beyond surface level, practical patterns, deep understanding
4. Originality — Unique approach or just packaging existing docs/tools

Stars	Meaning	Examples
⭐⭐⭐⭐⭐	Exemplary — deep + original + comprehensive	gh (mental model), mcp-builder (evaluation tools), kaizen (code adaptation)
⭐⭐⭐⭐	High quality — good depth + well-structured	dignified-bash, linux-sysadmin, meeting-insights-analyzer
⭐⭐⭐	Solid — complete but shallow/standard	changelog-generator (just workflow), opencode-config (config reference)
⭐⭐	Incomplete — needs expansion or examples	software-architecture, web-artifacts-builder, web-design-guidelines

Why downgraded from 5→3 stars?

• Just a workflow without deep insights (changelog-generator)
• Simple reference/config guide (git-workflow-manager, opencode-config)
• Packaging existing docs without original approach (vercel-react-best-practices)
• Utility skill without depth (claude-md-redirect)

Check Notes column for specifics. See SKILLS-REVIEW-REPORT.md for detailed improvement roadmap.

Claude Code Bug: Plugins Not Loading

Some Claude Code versions silently skip installed plugins if they are not explicitly listed in the enabledPlugins map in ~/.claude/settings.json. Older versions loaded all installed plugins automatically, but newer versions may require this explicit flag. When affected, skills and agents simply don't appear in the session — no error, no warning.

Symptoms: You install a plugin, but its skills don't show up in /skills. The plugin is listed in ~/.claude/plugins/installed_plugins.json but missing from enabledPlugins in ~/.claude/settings.json.

Fix: Run the included utility that syncs the two files:

python3 meta/utils/fix-enabled-plugins/fix-enabled-plugins.py

It shows diagnostics (installed vs enabled count), a diff of what's missing, creates a backup, and applies the fix. Safe to run multiple times. See fix-enabled-plugins README for details.

Alternative Installation

Use as local plugin directory (development mode):

claude --plugin-dir /path/to/oh-my-claude-plugins
