explore

A codebase exploration assistant that uses a code property graph, a structured map of code definitions and relationships, to investigate a project.

In plain words
What is it for?
Use it to locate functions, classes, and routes; trace calls and data flow; inspect architecture; find implementations; and investigate the intent and contracts behind code.
Why use it?
It helps developers understand how code is connected instead of only finding matching text, making dependency and call-chain discovery clearer.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

explore scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

explore is an agent published in the GitHub repository alinaqi/maggy (705 stars, last pushed 15d ago), licensed MIT. It adds 38 tokens to every session and 536 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
