Find Feature Implementation

Help locate where a specific feature or concept is implemented in the codebase.

Workflow

1. **Parse input**: Extract feature description from $ARGUMENTS

2. **Semantic search**: Use `hybrid_search` with the feature description to find semantically relevant code (combines BM25 + TF-IDF via Reciprocal Rank Fusion)

3. **Symbol search**: Use `workspace_symbol_search` with key terms from the feature to find related symbols

4. **For promising candidates**:

• Use `find_symbol_usages` to see how widely each candidate is used
• Use `get_symbol_definition` to read the actual implementation

5. **Trace connections** (if call-graph enabled):

• Use `get_callers` and `get_callees` to understand how the feature integrates

6. **Present findings**:

• Primary implementation location(s)
• Key functions/classes involved
• How the feature is invoked/used
• Related files and modules

Arguments
