codebase-mapper

A tool that explores an unfamiliar software project and creates a readable guide showing how its parts connect, with diagrams and explanations of domain terms.

In plain words
What is it for?
Use it to create or maintain project documentation, map integrations and rules, and explain a codebase to different audiences.
Why use it?
It reduces the time needed to understand a codebase and can reveal when documentation no longer matches the code.

Grade A, and why

codebase-mapper 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 yesterday.

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.

  "description": "Human-readable codebase guide generator: explores unfamiliar projects, builds a structured interconnect map (contracts, invariants, domain rules, integration hot-spots) via the codebase-xray semantic-interconnect-mapper, then autonomously profiles the project (type, audience, register) and produces audience-adaptive narrative documents with Mermaid diagrams that cite the map, including a plain-language executive summary and a domain glossary so the guide is comprehensible by everyone. Includes documentation-reality drift detection in the review phase, plus standalone documentation creation, maintenance, and humanization with bottom-up code analysis. Both docs-create and docs-maintain cover 20 documentation dimensions; docs-maintain runs a structured per-dimension drift audit (added/removed/renamed/retyped) instead of generic outdated-text matching.",

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.
