cursor-doctor

Your Cursor rules have bugs. This finds them.

You wrote rules. Cursor still ignores them. cursor-doctor tells you exactly what's wrong: conflicting directives, broken globs, vague instructions the AI can't act on, token budget waste, and 100+ other issues. One command. Zero dependencies.

npx cursor-doctor scan

What you get

  ▒▒ Cursor Health: B ▒▒

  ██████████████████████████░░░░  84%

  ✗ Conflict: "always use semicolons" vs "omit semicolons" in 2 files
  ✗ Glob *.tsx doesn't match any files in your project
  ⚠ 3 rules use alwaysApply — burning 2,400 tokens on every request
  ⚠ "write clean code" is too vague for the AI to act on
  ✓ Frontmatter valid across 12 rules
  ✓ No legacy .cursorrules detected

  8 passed  4 issues  (2 auto-fixable)

Not generic warnings. Issues specific to your rules, with the exact file and line.

Why this exists

We scanned 50 real open-source projects and found that 82% had at least one broken or misconfigured rule. The most common issues: contradictory instructions across files, glob patterns that match nothing, and vague rules the AI silently ignores.

What it checks

100+ lint rules:

• Conflicts — contradictory instructions across files (48 semantic patterns)
• Syntax — broken YAML frontmatter, boolean strings, unclosed code blocks
• Token budget — rules burning context window, dead rules, excessive alwaysApply
• Globs — patterns that don't match files, regex in globs, overlapping coverage
• Prompt quality — vague instructions, first person, politeness tokens, negation-only rules
• Structure — file naming, duplicate content, missing descriptions, legacy .cursorrules

Auto-fix (Pro)

34 auto-fixers: frontmatter repair, glob syntax, boolean strings, whitespace, TODO removal, duplicate descriptions, heading normalization, and more.
