map

A command that maps which CPython C files include one another and shows related API boundaries. CPython is the main implementation of the Python programming language.

In plain words
What is it for?
Use it to map the entire project or a selected directory, module, or file before a deeper C-code review.
Why use it?
It gives you a quick view of the project’s structure and dependencies before you investigate a particular part of the code.

Getting it into your agent

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

map 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 2d 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

Include Graph Map

Run only the include-graph-mapper agent to quickly understand CPython's C file structure, include dependencies, and API tier boundaries.

Scope: "$ARGUMENTS" (default: entire project)

Workflow

  1. Identify CPython project root (look for Include/Python.h and Objects/object.c)
  2. Launch include-graph-mapper agent with specified scope
  3. Present the include graph directly — no synthesis needed

This is the fastest way to get oriented in a CPython C codebase. Use this before diving into specific analysis with other commands.

Usage

/cpython-review-toolkit:map                  # Map entire project
/cpython-review-toolkit:map Objects/         # Map Objects directory
/cpython-review-toolkit:map Modules/_io/     # Map specific module
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.

map is a command published in the GitHub repository ReviewToolkits/cpython-review-toolkit (10 stars, last pushed 1mo ago), licensed MIT. It adds 13 tokens to every session and 221 once invoked, about $0.0001 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 2026-08-31.
