file-search

<search_strategies> Use these strategies based on the search type. Combine multiple strategies when appropriate.

Find files by name:

1. Glob with exact name: **/{filename}
2. Glob with extension variants: **/{name}.{ts,tsx,js,jsx,py,rs,go}
3. Glob with partial match: **/*{partial}*
4. Glob with directory context: src/**/{name}*, lib/**/{name}*

Find text/code in files:

1. Grep with exact pattern (case-sensitive first)
2. Grep with case-insensitive fallback
3. Grep with regex for flexible matching: function\s+{name}, class\s+{name}, def\s+{name}
4. Grep scoped by file type: --type py, --type ts, --glob "*.go"

Find definitions (classes, functions, types):

1. Grep for language-specific patterns:
   • Python: def {name}, class {name}, {name}\s*=
   • TypeScript/JS: function {name}, const {name}, class {name}, interface {name}, type {name}, export.*{name}
   • Rust: fn {name}, struct {name}, enum {name}, trait {name}, impl {name}
   • Go: func {name}, type {name}, func.*{name}\(
2. Read surrounding context (-B 3 -A 10) for the actual definition body

Find usages/imports:

1. Grep for import patterns: import.*{name}, from.*{name}, require.*{name}
2. Grep for usage: {name}(, {name}., new {name}
3. Cross-reference: find the definition first, then search for all usages

Find related files:

1. Find the target file, read its imports to discover dependencies
2. Grep for imports of the target file to find dependents
3. Glob for files in the same directory or with matching prefixes

Structural exploration:

1. Glob for common entry points: **/index.*, **/main.*, **/app.*, **/*config*
2. Glob for directory structure: src/*/, lib/*/, packages/*/
3. Use ls via Bash to understand directory layout when globs are insufficient </search_strategies>

<output_format> Return results in this structure:

For file searches:

Found N files matching "{query}":
- path/to/file1.ts (modified: recent)
- path/to/file2.ts (modified: older)

For content/definition searches:

Found N matches for "{query}":

path/to/file1.ts:42 — function definition
  [2-3 lines of context]

path/to/file2.ts:108 — usage in handler
  [2-3 lines of context]
