simon-report

simon-report is a skill for Claude Code from SW-in-beta/simon-skills. It costs 149 tokens per session (5,780 once invoked), scanned A, original, MIT.

A pre-work analysis workflow that studies a codebase and produces documents such as technical proposals, current-state reports, or RFCs. An RFC is a written plan used to discuss and decide on a technical change.

In plain words
What is it for?
Use it before a new feature or technology, for architecture reviews, technical investigations, and other reports that support engineering decisions.
Why use it?
It helps teams understand an existing system and compare options before changing code. The analysis is kept separate from implementation.

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-report 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.

simon-report

사전 분석 보고서 작성 스킬. 전문가팀 토론 기반 심층 분석 후 사용자 지정 양식으로 문서를 생성합니다.

자율주행모드 ON 입니다. 여러 Agent와 병행하여 딥하게 조사해주세요. 이 선언은 CLAUDE.md의 모호성 확인 규칙보다 우선한다 — 분석 진행 중 세부 모호함은 스스로 판단해 진행한다. 단, 분석 대상 자체(코드/레포/질문)가 특정되지 않는 수준의 모호함은 시작 전 1회만 확인한다.

Instructions

You are executing the simon-report skill. This skill analyzes a codebase topic using expert team discussions (from simon's domain team structure) and produces a pre-implementation document in the user's chosen format.

This is NOT a post-implementation report. It is a PRE-work analysis document (RFC, 현황 분석, 기술 제안서 등).

도구 제한: 이 스킬은 분석용이다. 프로젝트 소스 코드를 Edit/Write하지 않는다. 보고서 파일(~/claude-reports/)만 Write한다.

Shared Protocols: ~/.claude/skills/_shared/preamble.md 읽기 — Session Isolation, Error Resilience, Forbidden Rules, Agent Teams, Cognitive Independence 공통 프로토콜 포함.

Session Isolation Protocol (확장 — Report 전용)

Report 세션의 SESSION_DIR은 타임스탬프 기반으로 결정한다:

PROJECT_SLUG=$(git rev-parse --show-toplevel | tr '/' '-')
SESSION_ID="report-$(date +%Y%m%d-%H%M%S)"
SESSION_DIR="${HOME}/.claude/projects/${PROJECT_SLUG}/sessions/${SESSION_ID}"
mkdir -p "${SESSION_DIR}/reports"
echo "${SESSION_DIR}" > ~/.claude/.report-readonly-active

Read-Only Guard Hook

report-readonly-guard.sh(PreToolUse, Write|Edit)가 report 세션 중 보고서 디렉토리 밖 파일 수정을 결정론적으로 차단한다. 활성화 방식:

  • Startup에서 marker 생성: echo "${SESSION_DIR}" > ~/.claude/.report-readonly-active
  • hook은 marker가 존재할 때만 동작하며, {SESSION_DIR}/ 하위와 ~/claude-reports/ 하위만 허용
  • 스킬 종료(정상/중단 모두) 시 marker 제거: rm -f ~/.claude/.report-readonly-active

Reference Loading Policy

트리거 읽을 파일
Step 3 Domain Expert 진입 references/domain-teams.md

What ships with it

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.
