Scans a real codebase and writes coding-conventions.md from what it actually finds — variable style, SQL patterns, error handling, INSERT strategy, naming. Run once on any new project to bootstrap the convention system. Triggers on "scan conventions", "generate conventions", "bootstrap conventions", "extract conventions from code", "what are the conventions".
Security audit — checks auth, SQL injection, exposed endpoints, and sensitive data. Triggers on "security check", "is this secure", "check for vulnerabilities", "check auth", "audit security", "security audit".
Use when switching environments, updating config values, or verifying URLs/settings. Triggers on "check environment", "switch to production", "update URLs", "check config", "is this prod-ready".
Use when verifying a feature works, after making changes, or before shipping. Triggers on "verify this works", "test this", "does this work", "run the checklist", "before I ship", "check this end to end".
Use when cleaning up, simplifying, or restructuring existing code without changing behavior. Triggers on "refactor", "clean up", "simplify this", "this is getting messy", "too long", "hard to read", "extract this".
Use when the user wants to review a file for bugs, antipatterns, or quality issues. Triggers on "review", "check for issues", "look for problems", "audit", "before I ship".

Evaluates interface usability using Nielsen's 10 heuristics + Krug's "Don't Make Me Think" principles. Returns a severity-scored list of what's broken and why.
Users scan, they don't read. They satisfice, they don't optimize. They muddle through, they don't figure out.
"Every page should be self-evident. If something requires thinking, it's a usability problem." — Steve Krug
Drop a user on any random page. Can they immediately answer:
If any answer requires effort, the navigation is broken.
| # | Heuristic | What to Check |
|---|---|---|
| 1 | Visibility of System Status | Loading indicators? Form submission feedback? Current state visible? |
| 2 | Match System and Real World | Jargon-free labels? Natural reading order? Icons match mental models? |
| 3 | User Control and Freedom | Undo available? Cancel on every modal? No dead ends? |
| 4 | Consistency and Standards | Same action = same label? Button styles consistent? |
| 5 | Error Prevention | Confirmation for destructive actions? Inline validation? Disabled states? |
| 6 | Recognition Rather Than Recall | Options visible? Recent items surfaced? Labels on icons? |
| 7 | Flexibility and Efficiency | Keyboard shortcuts? Bulk actions? Search as navigation? |
| 8 | Aesthetic and Minimalist Design | Only essential info visible? Progressive disclosure? White space? |
| 9 | Help Recover from Errors | Plain language? Specific not generic? Suggest a fix? |
| 10 | Help and Documentation | Searchable? Task-focused? Concrete steps? |
| Severity | Label | Priority |
|---|---|---|
| 0 | Not a problem | Skip |
| 1 | Cosmetic | Fix if time permits |
| 2 | Minor | Fix in next iteration |
| 3 | Major | Fix before shipping |
| 4 | Catastrophic | Fix immediately |
| # | Heuristic Violated | Issue | Severity | Recommendation |
|---|---|---|---|---|
| 1 | H8: Minimalist Design | Dashboard shows 12 metrics above fold | 2 | Progressive disclosure: show top 4, expand for rest |
| 2 | H1: System Status | No loading indicator on search | 3 | Add spinner or skeleton screen |
Sort by severity (highest first). Summary: total issues, count by severity, top 3 fixes.
