code-wiki

code-wiki is a skill for Claude Code, Codex from sairam0424/MindForge. It costs 15 tokens per session (3,596 once invoked), scanned C, a copy of code-wiki, MIT.

A generator for reference documentation about a software codebase, including explanations of its structure and Mermaid diagrams. Mermaid is a text format for diagrams that can render in places such as GitHub.

In plain words
What is it for?
Use it to create a wiki with an overview, architecture description, module deep-dives, class diagrams, and sequence diagrams.
Why use it?
It gives developers a structured way to understand an unfamiliar codebase without manually assembling an overview and architecture diagrams.

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 C, and why

code-wiki scanned grade C with 1 finding 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 1mo 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

If you cloned to a temp dir, remind the user it can be removed (`rm -rf "$WIKI_TMP"`) after they've reviewed the wiki.
Origin

This is a copy

92% identical to code-wiki — 37 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 439 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Wiki Skill

Generate a comprehensive wiki for any codebase — overview, architecture, per-module deep-dives, Mermaid class and sequence diagrams. Inspired by Google CodeWiki, but works on local repos, private repos, and any language. Uses only existing tools (Bash, Read, Grep, Write); no Docker, no external services, no extra dependencies.

This skill produces reference documentation (what/how). It does not produce strategic narrative (why — that's a different skill).

When to Use

  • User says "document this codebase", "generate a wiki", "make architecture diagrams"
  • Onboarding to an unfamiliar repo and wants a structured reference
  • User points at a GitHub URL and asks for documentation
  • Need a stable artifact (markdown + Mermaid) that renders on GitHub

Do NOT use this for:

  • Single-file or single-function documentation — just answer directly
  • API reference for one specific endpoint — use Read and answer inline
  • Strategic "why does this exist" narrative — different skill, different purpose
  • Codebases the user is actively developing in this session — just answer questions as they come

Prerequisites

  • No env vars required.
  • git on PATH for repo SHA tracking and remote clones.
  • Optional: pygount for language-breakdown stats (see the codebase-inspection skill).

How to Run

Invoke through the Bash tool from the target repo's root, then use Read / Grep / Write to produce the wiki. Default output location is ~/.agent/wikis/<repo-name>/. Only write into the repo (docs/wiki/) when the user explicitly requests it.

Quick Reference

Step Action
1 Resolve target — local cwd, given path, or git clone --depth 50 <url> to a temp dir
2 Scan structure — ls, find -maxdepth 3, manifest files, README
3 Pick 8–10 modules to document
4 Write README.md (overview + module map)
5 Write architecture.md with Mermaid flowchart
6 Write per-module docs in modules/
7 Write diagrams/class-diagram.md (Mermaid classDiagram)
8 Write diagrams/sequences.md (Mermaid sequenceDiagram, 2–4 workflows)
9 Write getting-started.md
10 Write api.md if applicable, else skip
11 Write .codewiki-state.json
12 Report paths to user

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
