.agents/skills/typescript-advanced-types/SKILL.md

typescript-advanced-types is a skill for Claude Code, Codex from yeasin2002/twist-toast. It costs 57 tokens per session (4,979 once invoked), scanned A, original, no licence file.

A set of TypeScript techniques for describing complex relationships between types, including reusable type patterns and rules checked before the code runs.

In plain words
What is it for?
Use it when building reusable type utilities, conditional type rules, generic code, mapped types, template-based types, or other advanced TypeScript type logic.
Why use it?
It helps catch type mistakes during development and avoid repeating complicated type definitions across a project.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is yeasin2002/twist-toast's own configuration. It tells Claude Code and Codex how to work on twist-toast 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 twist-toast 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

typescript-advanced-types 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 9d 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.
