m05-type-driven

m05-type-driven is a skill for Claude Code, Codex from kikakkz/wait-agent. It costs 60 tokens per session (1,040 once invoked), scanned A, original, no licence file.

A guide to designing Rust types so that invalid combinations are rejected by the compiler. It covers type-state patterns, newtypes, marker traits, builders, and compile-time validation.

In plain words
What is it for?
Use it when modeling valid states, enforcing construction rules, validating builders, or separating values that share the same underlying type.
Why use it?
It moves some checks from runtime into the type system, reducing the chance of using an object incorrectly. It also makes important rules visible in function signatures.

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

m05-type-driven 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 5d 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.
