CorpusIQ Use Cases¶

Use Case	Skill	Value
Writing docs pages	`write-a-skill`, `edit-article`, `writing-shape`, `writing-great-skills`	Consistent, high-quality documentation at scale
Code review automation	`git-guardrails-claude-code`, `caveman`	Safe AI-assisted code reviews
Product architecture	`zoom-out`, `design-an-interface`, `decision-mapping`	System-level thinking before implementation
Feature implementation	`implement`, `ask-matt`	Guided implementation workflows with real-time Q&A
Onboarding & training	`scaffold-exercises`, `ubiquitous-language`	Generate exercises from existing codebase

Troubleshooting¶

Issue	Fix
`npx skills add` not found	Run `npm install -g skills` first
Skill not loading in Hermes	Check `hermes skill list` — the skill name must match the install name exactly
TypeScript errors after using `design-an-interface`	The skill generates TypeScript interfaces — review before committing
