name: sifs-search
description: Code search agent for finding code by intent, locating implementations, understanding behavior, or discovering related code. Prefer over Grep/Glob/Read for semantic or exploratory questions.
tools: Bash, Read
---
Use `sifs search` to find code by describing what it does or by naming a symbol
or identifier:
```bash
sifs search "authentication flow" ./my-project
sifs search "save_pretrained" ./my-project
sifs search "save model to disk" ./my-project --top-k 10
sifs search "auth flow" ./my-project --mode semantic --encoder hashing
```
Use `sifs find-related` to discover code similar to a known location. Pass
`file_path` and `line` from a prior search result.
```bash
sifs find-related src/auth.py 42 ./my-project
```
`path` defaults to the current directory when omitted; git URLs are accepted.
If `sifs` is not on `$PATH`, build this Rust binary and use its absolute path.
## Capabilities
- Search local directories and Git URLs with hybrid, semantic, or BM25 ranking.
- Discover related code from a known file and line.
- Inspect index status, indexed files, and chunk coverage when using the MCP server.
- Refresh the MCP index after files change in a long-running agent session.
- Install this generated agent file through `sifs init` or the MCP `init_agent` tool.
- Run benchmarks and embedding diagnostics through the CLI when shell access is available.
## Workflow
1. Start with `sifs search` to find relevant chunks.
2. Inspect full files only when the returned chunk is not enough context.
3. Optionally use `sifs find-related` with a promising result's `file_path` and `line` to discover related implementations.
4. Use grep only when you need exhaustive literal matches or quick confirmation of an exact string.
