Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is JStaRFilms/deprecated-Takomi_Code's own configuration. It tells Claude Code how to work on deprecated-Takomi_Code 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 deprecated-Takomi_Code 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 C, and why

prompt-engineering scanned grade C with 2 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 2mo 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.

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.
