explore

explore is a skill for Claude Code from sdsrss/code-graph-mcp. It costs 55 tokens per session (285 once invoked), scanned A, original, MIT.

A guide for exploring a codebase through its indexed structure before opening files one by one. It can show project or module structure, find symbols by concept, trace callers, and estimate what an edit may affect.

In plain words
What is it for?
It helps map a project, inspect a module, search for a concept, see what calls a symbol, and review likely impact before editing.
Why use it?
It reduces repetitive file reading and helps locate the right code before making a change. It also exposes related code that could be affected by an edit.

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 16d 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 Code (indexed project)

Use these BEFORE reading individual files:

Need Command Replaces
Module structure code-graph-mcp overview <dir> 5+ Read calls
Project architecture code-graph-mcp map --compact ls + README
Who calls / what calls code-graph-mcp callgraph <symbol> Grep + manual trace
Find by concept code-graph-mcp search "concept" (full-text) 3+ Grep attempts
Impact before a signature change code-graph-mcp impact <symbol> Grep for callers
Every use (rename / remove) code-graph-mcp refs <symbol>, then grep -w Grep alone

Workflow: overview first → Read only the file you will edit. Calls the graph could not resolve (dynamic dispatch, reflection, unresolved imports) are not in it, so confirm an empty answer with grep.

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 a skill published in the GitHub repository sdsrss/code-graph-mcp (84 stars, last pushed 2d ago), licensed MIT. It adds 55 tokens to every session and 285 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-14.

why

Work out whether a failure is your machine or your code before debugging either, using the environment this repository has declared and the dependency map. Use when a test, build or command fails and the cause is not obvious from the error.
