This skill emulates Cursor's rule selection behavior for AI agents.

It discovers and selects rules from:

Rule Type	Selection Behavior
`alwaysApply: true`	Always included
Simple `.md` (no frontmatter)	Always included
`globs: ...`	Included when any candidate file matches
`description: ...`	Included when prompt overlaps with description keywords
No metadata ( `.mdc` only)	Included only when explicitly referenced
`AGENTS.md`	Always included when in scope (directory hierarchy)

Candidate files come from

--files

,

--use-git-diff

, and file-like paths found in

--prompt

.

No Python, Node, or jq required.

Run commands from this skill directory (the directory containing this

SKILL.md

). Do not hardcode agent install paths.

bash

bash scripts/fetch_rules.sh --prompt "<your request>"

Optional file hints:

bash

bash scripts/fetch_rules.sh --prompt "<request>" --files path/to/a.ts path/to/b.sql
bash scripts/fetch_rules.sh --prompt "<request>" --use-git-diff

Force-include a rule by filename:

bash

bash scripts/fetch_rules.sh --prompt "<request>" --explicit global.mdc
bash scripts/fetch_rules.sh --prompt "<request>" --explicit react-patterns.md

Format	Location	Description
`.mdc`	`.cursor/rules/`	Rules with YAML frontmatter for fine-grained control
`.md`	`.cursor/rules/`	Simple markdown rules (always applied)
`AGENTS.md`	Root or subdirs	Simple agent instructions (always applied in scope)
`.cursorrules`	Root only	Legacy format (deprecated, will be removed)

If multiple rules share the same filename, the rule in the closest scoped directory wins (deepest scope).
Glob matching uses bash pattern matching (
```
[[ file == pattern ]]
```
). Cursor-style
```
**
```
works effectively as
```
*
```
in this matcher.
```
AGENTS.md
```
files are combined hierarchically—parent directories' instructions apply alongside more specific subdirectory instructions.
