# File Search Skill

Efficient CLI search tools for AI agents.

## Tool Selection Guide

| Task | Use | Instead of |
|------|-----|------------|
| Search text in code files | `rg` (ripgrep) | `grep`, `grep -r` |
| Find files by name/path | `fd` | `find`, `ls -R` |
| Structural/syntax-aware code search | `sg` (ast-grep) | regex hacks |
| Search PDFs, Office docs, archives | `rga` (ripgrep-all) | manual extraction |
| Count lines of code by language | `tokei` | `cloc`, `wc -l` |
| Code stats with complexity metrics | `scc` | `cloc`, `tokei` |

**Decision flow:** text/regex → `rg` | code structure (empty catches,
function sigs, multi-line patterns) → `sg` | files by name → `fd` |
PDFs/archives → `rga` | codebase stats → `tokei`/`scc`

## Quick Examples

```bash
rg 'def \w+\(' -t py src/          # rg: text search in Python files
rg -c 'TODO' -t js | wc -l         # rg: count first, then drill down
sg --pattern 'console.log($$$)' --rewrite 'logger.info($$$)' --lang js  # sg: structural replace
fd -g '*.test.ts' --changed-within 1d  # fd: -g for compound suffixes (NOT -e)
fd -g '*_test.go' -X rg 'func Test'   # fd+rg: find files, verify contents
rga 'quarterly revenue' docs/       # rga: search inside PDFs/archives
tokei --sort code                   # tokei: language stats
scc --wide                          # scc: complexity + COCOMO
```

## Best Practices

1. **Start narrow.** Specify types (`-t`, `--lang`, `-e`), scope dirs, count first (`rg -c`).
2. **Exclude noise** (`-g '!vendor/'`, `fd -E node_modules`).
3. **`--json`** for programmatic processing.
4. **rg ≠ fd types.** `rg -t ts` includes `.tsx`; `fd -e ts` does NOT. No `-t tsx` in rg.

## Beyond Local Files

If local search finds nothing and context lives in issues/PRs/external
docs — hand off (`gh`, Jira, WebFetch). Issue keys in comments signal this.

See [references/remote-handoff.md](references/remote-handoff.md).
