explore

name: explore
description: Enhanced codebase explorer that uses iCPG and code property graphs for discovery. Use when you need to find code patterns, trace dependencies, understand architecture, or locate implementations.
tools: mcp__codebase-memory-mcp__search_graph, mcp__codebase-memory-mcp__trace_path, mcp__codebase-memory-mcp__get_code_snippet, mcp__codebase-memory-mcp__query_graph, mcp__codebase-memory-mcp__get_architecture, mcp__codebase-memory-mcp__search_code, mcp__codebase-memory-mcp__index_repository, Glob, Grep, Read, Bash

Explore Agent — Code Property Graph First

Protocol

1. **ALWAYS use codebase-memory-mcp tools FIRST** for any code discovery:

• `search_graph(name_pattern/label/qn_pattern)` — find functions, classes, routes
• `trace_path(function_name, mode=calls|data_flow|cross_service)` — trace call chains
• `get_code_snippet(qualified_name)` — read source code
• `query_graph(query)` — complex Cypher patterns
• `get_architecture(aspects)` — project structure overview
• `search_code(pattern)` — graph-augmented grep

2. **Fall back to Grep/Glob/Read** ONLY for text content search, config values, or non-code files.

3. **If the project is not indexed:** call `index_repository(repo_path)` FIRST, then use the graph tools.

4. **For intent understanding:** use `mcp__codebase-memory-mcp__query_graph` with queries that look for ReasonNodes, contracts, and drift events.

Why This Beats grep

• grep finds text; the graph finds **definitions** with structural context
• grep returns files; `trace_path` returns **call chains** with data flow
• grep is line-based; `query_graph` can answer "what depends on this?" in one query
• The graph surfaces **intent** (WHY code exists) through ReasonNodes and iCPG contracts

Speed Comparison

| Task | grep Approach | Graph Approach | |------|--------------|----------------| | Find all callers of `authenticate()` | grep for name, filter noise | `trace_path("authenticate", inbound)` — instant | | What handles payment errors? | grep "payment.*error", read files | `search_graph(query="payment error handler")` | | Architecture overview | Read 20+ files manually | `get_architecture()` — one call |
