sync-docs is a command for Claude Code from Koshimizu-Takehito/my-toybox. It costs 0 tokens per session (1,945 once invoked), scanned A, original, MIT.

A documentation maintenance command that updates project information across README files, instructions, build files, package details, screen lists, and code comments. Documentation explains how a project works and how to use it.

In plain words
What is it for?
Use it to synchronize screen counts and command references across English and Japanese README files, contributor instructions, Makefile help, package documentation, and comments.
Why use it?
It reduces conflicting or outdated instructions when screens, commands, or other project details change.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is Koshimizu-Takehito/my-toybox's own configuration. It tells Claude Code how to work on my-toybox itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything my-toybox configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is [Relative Link](./docs/guide.md).

Reuse

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

sync-docs 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 4d 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.

Documentation Syncer

Maintain and update project documentation across all files.

Task

You are the documentation-writer agent. Your mission is to keep documentation accurate, synchronized, and helpful across README files, code comments, and project guides.

Documentation Files

Primary Documentation

  1. README.md (English)
  2. README.ja.md (Japanese)
  3. CLAUDE.md (Claude Code instructions)

Secondary Documentation

  1. Makefile (inline help text)
  2. Package.swift (package documentation)
  3. AppScreen.swift (screen enum cases)
  4. Code comments (inline documentation)

Sync Tasks

1. Update Screen Count

When screens are added/removed:

Files to Update:

  • README.md: Update count in project description
  • README.ja.md: Update count (Japanese version)
  • CLAUDE.md: Update count if mentioned

Example:

# Before
96+ visual effects screens

# After (when adding new screen)
97+ visual effects screens

2. Update Command Documentation

When Makefile commands change:

Files to Update:

  • README.md: Command reference section
  • README.ja.md: Command reference section
  • CLAUDE.md: Build & Development Commands section

Sync Steps:

  1. Read Makefile for all targets
  2. Extract help text and descriptions
  3. Update command tables in README files
  4. Ensure examples match actual commands

Example Makefile Target:

.PHONY: new-screen
new-screen:  ## Create new screen (interactive or with NAME=...)
	@bash Scripts/new_screen.sh $(NAME) $(SHADER)

Corresponding Documentation:

| Command | Description |
|---------|-------------|
| `make new-screen` | Create new screen (interactive or with NAME=...) |

3. Update Architecture Documentation

When architecture changes:

Files to Update:

  • README.md: Architecture section
  • CLAUDE.md: Architecture section

Key Areas:

  • Module structure changes
  • New patterns introduced
  • SPM plugin updates
  • Build system 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.
