my-toybox: Command for Claude Code

.claude/commands/README.md

README is a command for Claude Code from Koshimizu-Takehito/my-toybox. It costs 0 tokens per session (1,694 once invoked), scanned A, original, MIT.

A set of custom slash commands for common tasks in the MyToybox development project, including creating screens, checking code, debugging builds, and updating documentation.

In plain words
What is it for?
The commands help create visual-effects screens, debug Metal shaders and builds, review architecture, validate Swift code, update dependencies, and synchronize documentation.
Why use it?
It gives developers named workflows for recurring project tasks instead of requiring them to remember each step and tool.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; 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 →

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

README 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 6d 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 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.
