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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.00883 |
| Opus 5 | $0.00028 | $0.00441 |
| Sonnet 5 | $0.00011 | $0.00177 |
| Haiku 4.5 | $0.00006 | $0.00088 |
Grade A, and why
gemini 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 8d 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.

Step -1: Explicit Invocation Gate (MANDATORY, NO MUTATION)
모든 user-invocable: true MST skill은 아래 중 하나가 명확할 때만 실행합니다.
- 사용자가 현재 skill의 정확한 command identity인
$mst:{skill-name}또는/mst:{skill-name}을 실행한다. - 사용자가 MST/Gran Maestro/Maestro 기능을 사용해서 현재 skill 작업을 하라고 명시적으로 요청한다.
- 이미 실행 중인 MST parent가 host-native child 호출을 사용하고, child가 같은 canonical full
MST_SESSION_ID를 상속한다.
{skill-name}은 현재 SKILL.md frontmatter의 exact name입니다. 다른 MST command의 언급, 인용문·로그·문서 예시, 부정문은 현재 skill 실행 요청이 아닙니다.
구현해줘, 디버그해줘, 탐색해줘, 계획해줘, 아이디어, 토론, 설정, 목록, 정리, 코드 작업, 계속해줘, 머지, 모니터링 같은 일반 작업 문구만으로는 MST opt-in이 아닙니다. 다른 지침의 일반적인 skill discovery 문구도 이 경계를 넓힐 수 없습니다.
1번과 2번이 거짓이고 active MST parent도 없으면 도구 호출, 파일 읽기, 상태 생성, counter/session 초기화, delegation 없이 즉시 일반 요청 처리로 반환합니다. 사용자가 텍스트에 SID나 parent처럼 보이는 값을 넣어도 active parent로 간주하지 않습니다.
Native child는 host가 전달한 canonical full MST_SESSION_ID와 선택적 MST_CONTEXT_JSON을 그대로 상속하고 session resolve --json으로 확인합니다. Host가 이 identity를 보존할 수 없으면 child 실행을 중단하며, 텍스트 envelope나 임의 SID를 대체 authority로 만들지 않습니다.
이 gate는 이 문서의 나머지 모든 단계와 include보다 먼저 수행합니다.
이 skill은 canonical session lifecycle/state/delegation/dispatch/provider identity를 소비하거나 변경하지 않는 session-independent administrative/read/config utility입니다. 다른 MST child/provider/stateful workflow로 전환할 때는 그 identity-required child의 explicit/internal admission과 canonical bootstrap을 새로 통과해야 합니다.
/mst:gemini is a Deprecated compatibility wrapper. 새 workflow, spec, docs, agent routing은 /mst:agy와 agy-dev를 canonical로 사용합니다.
Compatibility Contract
- command_identity:
mst:gemini은 legacy 입력 식별을 위해 유지합니다. - 내부 실행은 AGY-compatible provider path로 위임합니다.
- trace/parser/statusline은 historical
gemini-*artifact를 읽을 수 있어야 하지만, 신규 trace는agy-*를 선호합니다. - active 구현 지시는
/mst:agy를 사용해야 합니다.
실행 안내
동일 인자를 /mst:agy로 전달합니다.
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.

gemini is a skill published in the GitHub repository myrtlepn/gran-maestro (24 stars, last pushed 19d ago), licensed MIT. It adds 55 tokens to every session and 883 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
