In plain words
What is it for?
It is for building Raycast extensions with TypeScript, including their configuration, commands, screens, and system interactions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

raycast-extension-creator 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 7d 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.

Raycast Extension Creator

Raycast Extension을 TypeScript로 생성하고 설정하는 스킬.

언제 사용하는가

  • Raycast Extension 개발 요청 시
  • List, Form, Detail 등 UI가 필요한 앱 요청 시
  • 클립보드 히스토리, HUD 알림, 폼 입력 등 Raycast API 필요 시
  • 기존 쉘 스크립트를 Raycast Extension으로 업그레이드할 때

Raycast Extension vs Script Command

구분 Script Command (.sh) Extension (TypeScript)
복잡도 단순 명령어 복잡한 로직/UI
API 접근 pbcopy/osascript Raycast API 전체
클립보드 히스토리 polling 방식 (불안정) Clipboard.copy (확실)
UI 없음 Form, List, Detail, Grid
사용 케이스 단순 스크립트 앱 수준 기능

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
