code-search

name	code-search
description	Routes code search requests to semantic, structural, repo-discovery, or text-search workflows. Use when the user wants to find code, inspect repository layout, or search by meaning or syntax.

Help the assistant choose the right code-search strategy for the task: start with repo discovery when needed, prefer osgrep for semantic search, use ast-grep for structural matching, and fall back to ripgrep for exact text search.

<quick_start> <default_order>

1. If the repo layout is unclear, load workflows/repo-discovery.md.
2. If the user wants "find code by meaning", load workflows/semantic-search.md.
3. If the user wants a structural pattern, load workflows/structural-search.md.
4. If the user wants a literal match, load workflows/text-search.md. </default_order>

Default to the `osgrep` CLI for semantic code search. If the repo does not have a usable root index, create or refresh it with `osgrep index` before searching. Confirm availability with `osgrep --help`; if unavailable, fall back to ripgrep-based discovery. Never start the `osgrep mcp` or `osgrep serve` background processes — use the CLI commands directly. What kind of code search do you want?

1. Find code by meaning or concept
2. Find code by structure or AST shape
3. Get the lay of the land in a repo
4. Find exact text or identifier matches

Wait for the answer, then follow the matching workflow.

<success_criteria> The right workflow is selected, the search strategy matches the task, and the assistant avoids using a heavier tool when a simpler one is enough. </success_criteria>
