source-command-lock

A workspace lock command that limits the current session to a chosen directory or project.

In plain words
What is it for?
It is for selecting a workspace, updating its session lock, and controlling whether handoff bootstrap files can influence that lock.
Why use it?
It helps prevent work from affecting files outside the intended workspace, while keeping locks separate between sessions.

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

source-command-lock 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 2d 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.

Command Template

/lock

사용법: /lock <workspace>

사용자는 workspace만 고른다. 세션 키는 Hames launcher/app runtime이 자동 주입한다 (HAMES_SESSION_ID, CODEX_THREAD_ID 등). 같은 모델을 여러 창/세션으로 띄워도 각 세션의 lock은 독립적으로 적용된다.

유효한 워크스페이스 (사용자 정의):

  • Tier 1 (entry 파일 보유): workspaces/<NAME>/ 아래 자체 CLAUDE.md/AGENTS.md를 둔 정식 워크스페이스. 사용자 본인의 워크스페이스 이름을 직접 사용.
  • Tier 2 (lock-only, entry 파일 없음): 단순 편집 범위 제한만 필요한 디렉토리. entry 파일 없이도 lock 가능.

범위 선택 패턴:

  • 컨테이너 전체 lock: 상위 디렉토리 이름 — 하위 자유 이동
  • 개별 프로젝트만 lock: 정확한 디렉토리 이름 — 형제 디렉토리 차단

실행 순서

/lock 실행 시 .hames_start_codex.md / .hames_start_gemini.md는 사용자가 handoff/resume 연속성을 명시적으로 요청했거나 해당 부트스트랩에 Session lock: ON이 있을 때만 읽고 적용한다. Session lock: OFF 부트스트랩은 lock 명령을 지연하거나 덮어쓸 수 없다.

Step 1 — Lock 파일 갱신

PowerShell로 lock helper를 실행합니다. 이 helper가 .claude/.workspace_lock 안의 현재 세션 항목만 갱신합니다.

powershell -ExecutionPolicy Bypass -File arsenal/set_workspace_lock.ps1 -Workspace <입력값>

예: /lock MyDomain → 현재 HAMES_SESSION_ID에만 MyDomain lock 적용

.claude/.workspace_lock은 세션별 map을 사용한다. 기존 전역 lock 형식도 하위 호환으로 유지된다.

Step 2 — 워크스페이스 컨텍스트 로드

해당 워크스페이스의 entry 파일을 읽어 로컬 규칙 적용. 환경별 우선순위:

  • Codex 앱 / Codex CLI: AGENTS.md 우선, 없으면 CLAUDE.md
  • Claude Code / Cursor: CLAUDE.md 우선, 없으면 AGENTS.md
  • Gemini CLI / Cursor (Gemini 모델): CLAUDE.md 또는 AGENTS.md 중 존재하는 것
  • entry 파일 없는 Tier 2 워크스페이스: 이 단계를 스킵하고 lock-only 모드로 진행
워크스페이스 종류 entry 경로
일반 워크스페이스 workspaces/<NAME>/CLAUDE.md (또는 AGENTS.md)
격리 도메인 (advanced) <DomainRoot>/CLAUDE.md + <DomainRoot>/AGENTS.md (선택)
Lock-only 디렉토리 (없음 — Step 2 스킵)

Step 3 — 격리 도메인 전용 준비 (해당 시)

격리 도메인은 자체 에이전트 팀과 hook을 가진다. Lock 시 해당 도메인의 <Root>/.claude/agents/ 디렉토리를 확인. 패턴은 docs/04_workspace_model.md 참조.

Step 4 — 상태 보고

[WORKSPACE LOCK] Active: <workspace> | Lock: ON
쓰기 차단 범위: 현재 세션에서 <workspace> 외부 모든 경로
읽기: 전체 허용 (Read/Glob/Grep 무조건 통과)
SYSTEM_ADMIN 경로 (arsenal, .claude, .codex, .gemini, .agents): 항상 허용
해제: "고정 해제" 입력

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.

source-command-lock is a skill published in the GitHub repository baek-labs/hames (5 stars, last pushed 1mo ago), licensed MIT. It adds 14 tokens to every session and 998 once invoked, about $0.0001 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 2026-08-31.
