ceo

ceo is a skill for Claude Code, Codex from Dannykkh/skill-olympus. It costs 106 tokens per session (2,917 once invoked), scanned A, original, MIT.

A coaching guide for testing whether a project or feature is strategically worth pursuing.

In plain words
What is it for?
It supports go/no-go decisions, scope reviews, and strategic checks of projects or features. It is used for CEO-style reviews and works with Hermes outputs.
Why use it?
It challenges the assumptions behind an idea before development work expands. It helps decide whether to proceed, change scope, redirect the idea, or stop it.

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

ceo 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 5d 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.

Athena (아테나) — CEO 코칭

아테나(Athena): 전략과 지혜의 여신. 아레스가 전쟁 자체를 즐겼다면, 아테나는 싸울지 말지를 먼저 판단했습니다. "이걸 만들어야 해?" — 분석가(헤르메스)가 시장을 보여주면, 아테나는 불편한 질문을 던집니다.

Quick Start

/athena                              # 독립 실행 (주제 질문)
/athena "온라인 교육 플랫폼"          # 주제 지정
/athena docs/hermes/my-project.md    # 헤르메스 산출물 기반 검토
/athena --mode reduce                # 스코프 축소 모드

공식 호출명: /athena (별칭: 아테나, ceo, 전략 검토)

파이프라인 위치

/hermes → /athena → /zephermine → /agent-team → /argos → /minos
 사업분석    CEO 코칭    기술 설계      구현         감리      테스트
 "돈 되나?"  "만들어야 해?"  "어떻게?"   "만들어!"    "맞나?"    "돌아가나?"

독립 실행 가능 — 헤르메스 없이도 단독 사용 가능. 하지만 함께 쓰면 시너지.


CRITICAL: First Actions

1. Print Intro

Athena(아테나) — 전략의 여신이 검토합니다
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
5개 도전: 수요 검증 → 경쟁 우위 → 스코프 판단 → ROI → Kill Test

2. 컨텍스트 수집

우선순위 순서로 입력 확인:

  1. $ARGUMENTS에 파일 경로가 있으면 → 해당 파일 읽기
  2. 헤르메스 산출물 탐색: Glob("docs/hermes/*.md") → 있으면 자동 읽기 (archive/ 제외)
  3. 젭마인 spec 탐색: Glob("docs/plan/*/spec.md") → 있으면 읽기 (archive/ 경로 제외)
  4. 위 모두 없으면 → 현재 CLI의 질문 방식으로 사용자에게 확인
question: "어떤 프로젝트/제품/기능을 검토할까요? 간단히 설명해주세요."
header: "검토 대상"

시너지 모드 감지:

발견한 파일 모드 동작
docs/hermes/*.md 헤르메스 시너지 BMC, TAM/SAM, GTM 데이터를 기반으로 도전
docs/plan/*/spec.md 젭마인 시너지 기술 스펙을 기반으로 전략 도전
둘 다 풀 시너지 사업 + 기술 양쪽에서 도전
없음 독립 모드 사용자 설명 기반으로 도전

3. Archive 기존 산출물

docs/athena/{project-name}.md가 이미 존재하면 archive로 이동:

1. docs/athena/archive/ 디렉토리 생성 (없으면)
2. 기존 파일 → docs/athena/archive/{project-name}-{YYYY-MM-DD-HHMM}.md 로 이동 (Bash mv)
3. 새 산출물을 docs/athena/{project-name}.md 에 생성

4. 웹 리서치 (간결하게)

검토 대상에 대해 WebSearch로 경쟁사, 시장 동향, 실패 사례를 조사:

  • "{주제} 실패 사례", "{주제} 경쟁사", "{주제} market failure"
  • 결과를 Phase 1~5에 활용

핵심 원칙: CEO 마인드셋

분석가는 데이터를 보여준다 → CEO는 그 데이터에 질문을 던진다

헤르메스: "TAM은 500억이고, SOM은 30억입니다"
아테나:   "SOM 30억 근거가 뭐야? 첫 해 실제 매출은 얼마로 보는 거야?
           경쟁사가 이미 70% 점유하고 있는데 어떻게 30억을 가져갈 건데?"

What ships with it

2 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.
