docs(skill): keep access-key secrets out of agent sessions

[luvs01]

Delivered — superseded by merged work

Verified in dev at 5759d9ea2f1e7281cdc01eb9628f2e0a123fb59c: #3789 (26fa36424a).

Original contribution: docs(skill): keep access-key secrets out of agent sessions, by @luvs01.

Agent-facing secret-bearing command and rotation-recipe restrictions, including aliases and management API spellings.

The original PR is closed as superseded; its contribution remains credited in the landed history.

Attribution strengthened by #3811, merged as cf9f662190c4c6770697c45c870941509cc98f9c. See CREDITS.md for the source-to-landing attribution record.

Summary

• Remove executable access-key creation from the agent-facing ocx rotation recipe and explicitly forbid agents from creating a key or starting a rotation because those operations return a one-time plaintext credential that can enter the agent transcript.
• Cover ocx and opencodex, the access key, access keys, and api-key spellings, plus direct POST /api/keys and POST /api/keys/rotate calls.
• Require configuration confirmation and then separate explicit approval before revoking the old credential; commit in-place rotations and reserve removal for separately created replacements.
• Add non-vacuous regressions that scan SKILL.md and every shipped ocx reference while allowing non-secret rotation commit and abort operations, including --json before the operation.

The human CLI contract is unchanged: key creation and rotation-start remain supported for an operator-run terminal. This PR changes only the agent skill safety boundary.

Verification

• bun test --isolate ./tests/skill-ocx.test.ts — 13 pass, 0 fail, 105 expect() calls on Bun 1.4.0 at rebased HEAD 7734e758b7.
• bun test --isolate ./tests/skill-ocx.test.ts ./tests/api-keys-routes.test.ts — 58 pass, 0 fail, 226 assertions in 61.28s on Bun 1.4.0 at the rebased HEAD.
• bun run skill:surface:check — passed.
• bun run privacy:scan — passed.
• bun run typecheck — passed.
• bun run test — the broad-suite attempt reached the 900s Windows guard and was terminated after timeout and ACL-hardening contention spread across unrelated suites; exact process readback found no survivor. GitHub CI is the broad-suite gate for this rebased HEAD.
• Codex skill validation — passed.
• Independent focused security review — clean. It covered creation and rotation-start, CLI aliases and executable wrappers, direct management-API POST routes, every shipped skill reference, the separate revocation approval, in-place commit versus separate-key removal, flag ordering, and non-vacuous detector fixtures.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

• Security

  • Added guidance preventing agents from creating or rotating access keys directly, including through aliases, command-line tools, or management API requests.
  • Added safeguards against sharing plaintext credentials or deleting existing keys before replacement configuration is confirmed.
  • Clarified that secret-bearing operations must occur outside the agent session with explicit approval.

📝 Walkthrough

Walkthrough

The OCX skill documentation prohibits agent-side access-key creation and rotation. The access-key recipe defines a user-mediated replacement workflow. Tests detect prohibited commands and verify session-boundary and approval guidance.

Changes

OCX access-key secret boundary

Layer / File(s)	Summary
Secret-bearing access-key guidance skills/ocx/SKILL.md, skills/ocx/references/03_recipes.md	The skill and recipe prohibit secret-bearing key commands in agent sessions. Users must perform these operations outside the session. The guidance restricts plaintext credentials, requires approval before committing or removing keys, and retains usage verification.
Documentation command detection tests/skill-ocx.test.ts	The tests detect access-key and API-key create or rotate commands, aliases, shell wrappers, line continuations, and management API requests. They exclude rotate commit, rotate abort, and /api/keys/rotate/commit, and verify the required session-boundary and approval text.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 7734e

OCX documentation now keeps secret-returning access-key operations outside agent sessions and requires confirmation before old-key removal. The updated guidance and regression checks support safe rotation behavior with no remaining merge-blocking risk.

- Around line 109-114: Update the key-rotation instructions around the old-key
removal step to commit an in-place rotation with ocx access key rotate commit
using the original key ID and rotation ID after the client accepts the
replacement; reserve ocx access key remove for separately created replacement
keys, and retain the subsequent key-list verification.

In `@skills/ocx/SKILL.md`:
- Around line 100-102: Require separate explicit user approval before revoking
the old access key, rather than treating configuration confirmation as
sufficient. In skills/ocx/SKILL.md lines 100-102, update the workflow to obtain
approval before removal; in skills/ocx/references/03_recipes.md lines 109-112,
add that approval immediately before running the old-key removal command.

In `@tests/skill-ocx.test.ts`:
- Line 166: Update the access-command detection pattern in the skill-ocx tests
so global flags such as json are accepted between rotate and the commit or abort
subcommand, without flagging those non-secret commands. Add regression cases
covering both rotate-with-json-commit and rotate-with-json-abort forms.

설명

이 PR은 에이전트가 ocx skill을 따라가다 액세스 키 평문을 터미널 출력으로 받아 모델 transcript에 넣는 길을 막는다. 지금 dev의 skills/ocx/references/03_recipes.md 레시피 5는 여전히 펜스 안에 ocx access key create rotated --json을 그대로 보여 주고, “plaintext key is in THIS response only”라고 적혀 있다. 에이전트가 그 블록을 실행하면 한 번만 나오는 데이터플레인 키가 세션 로그에 남을 수 있다. 이번 변경은 (1) SKILL.md에 “Secret-bearing commands” 절을 추가하고, (2) 레시피 5에서 create 명령을 펜스 밖으로 빼서 사용자에게 별도 터미널을 요청하도록 바꾸고, (3) tests/skill-ocx.test.ts에 펜스 안 시크릿 명령 탐지기를 넣어 회귀를 잠근다.

현재 HEAD ff1ac6b8c 기준으로 src/cli/access.ts / registry.ts를 보면 access key create, access key rotate <id>, 별칭 access keys·api-key, 실행 파일 opencodex가 모두 같은 표면에 있다. 탐지 정규식이 ocx|opencodex(+.exe/.mjs), access keys?|api-key, create|rotate(단 rotate commit|abort 제외)를 묶고, POST /api/keys·/api/keys/rotate와 curl/PowerShell 래퍼까지 보는 구성은 실제 CLI 별칭과 맞다. frontmatter description을 따옴표로 감싼 것도, 콜론이 있는 긴 스칼라를 YAML이 깨지 않게 하는 타당한 수정이다.

보안 가치가 문서 PR치고 높다. 다만 코드 경로의 키 발급 자체를 막거나 서버를 바꾸는 것은 아니고, 에이전트용 가이드·레시피·테스트 계약이다. types/config 분할과 무관하고 close-don't-rebase 대상도 아니다. hygiene·review-ready 초록이다.

skills/ocx/SKILL.md Secret-bearing commands - create/rotate 시작을 에이전트 세션 밖으로 밀어 내고, 평문 키를 채팅에 붙여 넣지 말며, 교체 설정 확인 전에 옛 키를 지우지 말라고 못 박은 문장은 운영 실과 맞다.

skills/ocx/references/03_recipes.md 레시피 5 - 펜스에서 create를 제거한 것이 핵심이다. list → (사용자 create) → remove 순서로 바뀌어, 에이전트가 복사-실행으로 키를 받을 수 있는 예시가 사라진다.

tests/skill-ocx.test.ts secretBearingCommandsInFences - 코드펜스만 검사한다. 본문 prose에 백틱 한 줄로 명령을 써도 탐지되지 않는다. 지금 SKILL/레시피는 서술로 이름을 말하고 펜스에서는 빼 두었으므로 통과하지만, 나중에 prose 백틱으로 create를 다시 넣으면 테스트가 못 잡는다.

탐지기가 rotate commit / rotate abort와 /api/keys/rotate/commit은 허용한다 - 평문을 새로 발급하지 않는 마무리 단계라 분기가 맞다. 셸 연속 줄(\ / ` / ^) 접기도 우회를 줄인다.

메인테이너의 판단이 필요한 지점

• 펜스뿐 아니라 inline 백틱 명령까지 금지할 정도로 탐지기를 키울지 (지금은 펜스 중심이라 실용적 타협)
• 에이전트 skill 외에 사람용 docs/README에 남아 있는 create 예시까지 같은 톤으로 맞출지 (이 PR 범위 밖)

너의 추천
머지해도 된다. dev에 남아 있던 “에이전트가 create를 실행하라”는 skill 레시피를 끊고, 별칭·관리 API POST까지 회귀로 잠근 문서 보안 수정이다. Meta 프로바이더 열차와 안 겹친다. inline 백틱까지 잠글지는 후속으로 충분하다.
