What is guide CLAUDE.md?

Repository instructions for a documentation project that treats Markdown files as the main source for engineering standards and creates GitHub Wiki pages and AI-assistant rule files.

Maintaining the documentation repository, building and testing its Go tools, syncing documents to a GitHub Wiki, generating assistant rules, and checking the table of contents.

They give a coding agent the project context, build and test commands, and checks needed to keep generated documentation in sync.

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.

Model	Per session	Once invoked
Fable 5	$0.01701	$0.01701
Opus 5	$0.00851	$0.00851
Sonnet 5	$0.00340	$0.00340
Haiku 4.5	$0.00170	$0.00170

Security

Grade A, and why

guide CLAUDE.md 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

A documentation repository that serves as the single source of truth for software engineering standards. It contains 80+ Markdown files organized hierarchically and includes two Go-based automation tools that transform this documentation into GitHub Wiki pages and AI assistant rule files (for Claude Code, Cursor, Codex, and GitHub Copilot).

Build, Test, and Validate

There is no Makefile. The two Go tools are built and tested independently:

# update-wiki tool (Go 1.26.2) — syncs docs to GitHub Wiki
cd .github/workflows/update-wiki
go build -o update-wiki ./...
go test ./...

# generate-ai-rules tool (Go 1.26.2) — generates AI rule files from docs
cd .github/workflows/generate-ai-rules
go build -o generate-ai-rules ./...
go test ./...

# TOC sync validation (run from repo root)
bash .github/workflows/sync-docs/check-toc-sync.sh

Build times are ~1 second each. Set timeouts to 60+ seconds for safety.

Architecture

Documentation Flow

Markdown files (source of truth)
  ├─→ update-wiki tool ─→ GitHub Wiki (flattened links, absolute image URLs)
  ├─→ generate-ai-rules tool ─→ 'generated' branch (claude/, cursor/, codex/, copilot/)
  │   ├── Claude Code, Cursor, Codex, GitHub Copilot rule files
  │   ├── Static assets (agents, commands, skills, hooks) ─→ copied to 'generated' branch
  │   └── aisync-source.yaml ─→ source definition for aisync users
  ├─→ .claude-plugin/marketplace.json ─→ Claude Code plugin marketplace
  └─→ aisync (external tool) ─→ downloads from 'generated' branch to ~/.claude/, ~/.cursor/, etc.

The generated rule directories (claude/, cursor/, codex/, copilot/) do not exist on main. They live only on the generated branch, which is updated automatically by the generate-ai-rules.yaml workflow.

Go Tools

update-wiki (.github/workflows/update-wiki/main.go): Converts relative markdown links to Wiki-flat format (preserving any #anchor fragment) and resolves image paths to GitHub raw content URLs.
generate-ai-rules (.github/workflows/generate-ai-rules/): Parses documentation, extracts sections, and formats them into AI-assistant-specific rule files. Has separate config.go, parser.go, and formatter.go modules with corresponding tests.

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.

guide CLAUDE.md is an instructions file published in the GitHub repository rios0rios0/guide (2 stars, last pushed 2d ago), licensed MIT. It adds 1,701 tokens to every session, about $0.0085 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.
