implement-type-annotations

implement-type-annotations is a skill for Claude Code, Codex from ambient-code/agentready. It costs 30 tokens per session (212 once invoked), scanned A, original, MIT.

A coding workflow for adding type annotations, which describe the kinds of values that Python and TypeScript code accepts and returns.

In plain words
What is it for?
Use it to add types to function signatures and check how consistently a codebase uses them.
Why use it?
Clear types improve editor assistance and expose some mistakes before the program runs, while also giving AI tools more precise code context.

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

implement-type-annotations 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 1mo 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.
