codeindex - Semantic Code Search & Indexing

codeindex is a semantic code search CLI that indexes codebases and provides fast, concept-based search over the current project.

Ownership

The agent owns the codeindex lifecycle for the current project — initialization, indexing, and searching. Do not ask the user to perform these steps; handle them automatically.

Initialization: If codeindex search or codeindex index fails with an initialization error (e.g., "Not in an initialized project directory"), run codeindex init from the project root directory, then codeindex index to build the index, then retry the original command.
Index freshness: Keep the index up to date by running codeindex index when the index may be stale — e.g., at the start of a session, or after making significant code changes (new files, refactors, renamed modules). There is no need to re-index between consecutive searches if no code was changed in between.
Installation: If codeindex itself is not found (command not found), refer to management.md for installation instructions and inform the user.

Searching the Codebase

To perform a semantic search:

codeindex search <query terms>

To perform a sematic search filter by path:

codeindex search -path . "authentication logic"

Note: Flags must precede the query string.

The query should describe the concept, functionality, or behavior to find, not exact code syntax. For example:

codeindex search database connection pooling
codeindex search user authentication flow
codeindex search error handling retry logic

Filtering Results

By language (-lang): restrict results to specific languages (comma-separated).
```
codeindex search -lang python,markdown database schema
```
By path (-glob): restrict results to files matching glob patterns (comma-separated).
```
codeindex search -glob 'src/api/**' request validation
```
Limit results (-limit): maximum number of results (default: from config search_limit).
```
codeindex search -limit 10 database schema
```
Files only (-files): show only file paths and metadata without content.
```
codeindex search -files database schema
```
Hybrid search (-hybrid): combine vector embeddings with keyword matching (TF-IDF) for better precision with technical terms.
```
codeindex search -hybrid "EmbeddingProvider interface"
```
Score threshold: Results below score_threshold (from config) are automatically filtered out.

Hybrid Search:

Hybrid search combines semantic vector search with keyword matching:

Vector search: Understands semantic meaning ("database connection" → connection pooling code)
Keyword matching: Finds exact terms ("EmbeddingProvider" → exact interface name)
Combined score: vector_weight * vector_score + keyword_weight * keyword_score

Enable in config:

{
  "hybrid_search": true,
  "vector_weight": 0.7,
  "keyword_weight": 0.3
}

Or use per-query with -hybrid flag.

Pagination

Results default to the first page (limit: 5). To retrieve additional results:

codeindex search -offset 5 -limit 5 database schema

If all returned results look relevant, use -offset to fetch the next page — there are likely more useful matches beyond the first page.

Working with Search Results

Search results include file paths and line ranges. To explore a result in more detail:

Use the editor's built-in file reading capabilities (e.g., the Read tool) to load the matched file and read lines around the returned range for full context.
When working in a terminal without a file-reading tool, use sed -n '<start>,<end>p' <file> to extract a specific line range.

Settings

To view or edit embedding model configuration, include/exclude patterns, or language overrides, see settings.md.
