simon-sync

simon-sync is a skill for Claude Code from SW-in-beta/simon-skills. It costs 112 tokens per session (1,919 once invoked), scanned A, original, MIT.

A synchronization workflow for sending selected simon skills to the simon-skills open-source repository and updating its README. It can be triggered automatically after skill changes or run manually.

In plain words
What is it for?
Use it to synchronize approved simon skills, refresh their repository documentation, and automatically commit and push those updates.
Why use it?
It keeps the local and public copies of supported skills aligned and moves the longer synchronization work into a background agent.

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

simon-sync 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.

simon-sync

simon-* 스킬 패밀리의 변경사항을 ~/simon-skills 오픈소스 레포에 동기화하고, README를 전문가 수준으로 업데이트한 뒤, 자동 커밋 & 푸시하는 스킬.

트리거

  • 자동: PostToolUse 훅이 ~/.claude/skills/simon-* 파일 변경을 감지하면 마커 파일 생성 → Stop 훅이 이 스킬 실행 지시 (10분 쿨다운 적용)
  • 수동: /simon-sync 명령으로 직접 호출

자동 트리거 시 (Stop 훅에 의한 호출)

메인 세션의 컨텍스트를 보호하기 위해, 최소한의 작업만 수행하고 나머지는 백그라운드 Agent에 위임한다.

메인 세션에서 수행할 작업 (3단계로 즉시 완료):

  1. 마커 삭제 + 쿨다운 타임스탬프 갱신:

    rm -f /tmp/.simon-skill-sync-needed && touch /tmp/.simon-skill-last-sync
    
  2. 백그라운드 Agent를 spawn (run_in_background: true)하여 아래 "동기화 절차" 전체를 위임. Agent prompt에 동기화 절차 섹션 내용을 포함시킨다.

  3. 사용자에게 "동기화를 백그라운드에서 시작했습니다"라고 한 줄 안내 후 즉시 턴 종료.

절대로 메인 세션에서 동기화 절차를 직접 실행하지 않는다.

수동 호출 시

/simon-sync로 직접 호출된 경우에도 백그라운드 Agent로 실행한다. 동일한 3단계를 따른다.

동기화 절차

이 섹션은 백그라운드 Agent가 수행하는 작업이다.

Step 1: 동기화 대상 파악

동기화 대상 스킬 목록 (이 목록에 없는 스킬은 동기화하지 않는다):

  • simon
  • simon-auto-boost
  • simon-boost
  • simon-boost-capture
  • simon-boost-review
  • simon-ci-fix
  • simon-grind
  • simon-pm
  • simon-report
  • simon-code-review
  • simon-sessions
  • simon-company
  • simon-presenter

제외 대상:

  • simon-sync (이 스킬 자체 — 메타 스킬이므로 레포에 포함하지 않음)
  • *-workspace/ 디렉토리 (로컬 eval 데이터)
  • evals/ 디렉토리 (로컬 eval 데이터)
  • ~/.claude/skills/simon/workflow/ (레포의 workflow/에서 복사된 것)
  • ~/.claude/skills/simon/install.sh (레포의 install.sh에서 복사된 것)

Step 2: 파일 동기화

각 대상 스킬에 대해 rsync로 동기화한다:

rsync -av --delete \
  --exclude='evals/' \
  --exclude='*-workspace/' \
  ~/.claude/skills/<skill-name>/ ~/simon-skills/skills/<skill-name>/

simon 스킬은 추가 제외 필요:

rsync -av --delete \
  --exclude='evals/' \
  --exclude='*-workspace/' \
  --exclude='workflow/' \
  --exclude='install.sh' \
  ~/.claude/skills/simon/ ~/simon-skills/skills/simon/

Step 2.5: Secret Scanning (동기화 전 시크릿 검사)

rsync 완료 후, git commit 전에 동기화된 스킬 파일들의 내용을 검사하여 API 키, 토큰, 패스워드 등 민감 정보가 포함되지 않았는지 확인한다. 퍼블릭 레포에 시크릿이 푸시되는 것을 방지하기 위한 필수 단계.

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.
