Summary

Add opt-in projectContext: "on" provider configuration for Command Code (command-code).

When enabled on a command-code provider, opencodex loads bounded local repository context (AGENTS.md, taste.md, and workspace skills from skills/, .codex/skills/, and .agents/skills/) into the /alpha/generate payload instead of empty memory, taste, and skills fields.

  • Defaults to off (EMPTY_COMMAND_CODE_PROJECT_CONTEXT), preserving the existing behavior.
  • Robust, fail-soft loader: bounds file reads, enforces directory traversal limits, escapes XML characters, and caches results with LRU and TTL eviction.
  • Config schema and provider documentation updated.

Surface context: src/server/auth-cors.ts registers projectContext: "editor" in PROVIDER_CONFIG_FIELD_POLICY to satisfy TypeScript Record<keyof OcxProviderConfig, ProviderConfigFieldPolicy>. Maintainer sponsorship is requested per MAINTAINERS.md security review policy.

Verification

Refresh 2026-09-18: rebased onto upstream/dev 3d5efc725 (head c65170732): focused command-code tests 77/79 pass, typecheck clean; all 5 review threads verified satisfied and resolved. The 2 failures are sandbox-only (loopback bind blocked in OAuth login-flow test setup); needs hosted CI for a fully green box 1.

All verification commands executed via the isolated testing wrapper with clean temporary OPENCODEX_HOME and isolated ports:

  • bun test tests/providers/command-code-project-context.test.ts tests/providers/command-code-provider.test.ts: 73 passed, 0 failed (233 expect calls).
  • bun test tests/test-layout.test.ts tests/test-layout-tooling.test.ts: 17 passed, 0 failed (551 expect calls).
  • bun test tests/providers/provider-config-validation.test.ts tests/server/config.test.ts: 206 passed, 0 failed.
  • bun run typecheck: zero diagnostics.
  • bun run privacy:scan: passed cleanly.
  • Verified live config fingerprint and backup inventory in /Users/user/.opencodex remained completely untouched.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Added/updated regression coverage or verified existing coverage for the affected behavior.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

📝 Walkthrough

Walkthrough

The Command Code adapter now supports opt-in loading of bounded local project context. The loader reads memory, taste, and skills with path confinement, limits, timeouts, XML escaping, caching, and fail-soft behavior. Configuration, editor exposure, documentation, and tests were added.

Changes

Command Code project context

Layer / File(s) Summary
Configuration and request integration
src/types/provider.ts, src/config/schema/leaf-validators.ts, src/server/auth-cors.ts, src/adapters/command-code.ts, docs-site/src/content/docs/guides/providers.md
Adds optional projectContext: "off" | "on" configuration, exposes it through the editor policy, and includes loaded context in Command Code requests only when set to "on". The provider guide documents the default and opt-in behavior.
Bounded context collection
src/adapters/command-code-project-context.ts
Adds loading for AGENTS.md, taste.md, and skills. The loader confines paths to the canonical working directory, applies byte and scan limits, uses per-operation timeouts, escapes XML, filters and deduplicates skills, and fails soft on errors.
Context cache lifecycle
src/adapters/command-code-project-context.ts
Adds a 30-second cache with a 128-entry capacity limit, expiry pruning, and oldest-entry eviction.
Loader and cache validation
tests/providers/command-code-project-context.test.ts, tests/providers/command-code-provider.test.ts
Adds coverage for loading, precedence, truncation, timeouts, resource closure, symlink confinement, XML serialization, cache refresh, eviction, concurrent refresh behavior, and request-field selection.

리뷰 · 우선순위 44 / 80

이 PR은 Command Code(command-code) 제공자에 선택 옵션 projectContext: "on"을 넣습니다. 지금 dev(HEAD ed839a3ee, #4226 L1·#4227 L5가 막 올라간 상태)의 src/adapters/command-code.ts/alpha/generate 본문에 memory: "", taste: null, skills: null을 항상 비워서 보냅니다. 옵션을 켜면 새 파일 src/adapters/command-code-project-context.tsloadCommandCodeProjectContext()가 작업 폴더에서 AGENTS.md, .commandcode/taste/taste.md, 스킬 폴더를 읽어 그 세 칸을 채웁니다. 기본값은 끔(EMPTY_COMMAND_CODE_PROJECT_CONTEXT)이라 지금 동작은 그대로입니다.

점수가 중간인 이유는 일곱 레인 계획에서 L1/L5만 첫 구현이 들어갔고, Command Code 로컬 컨텍스트는 그 레인의 급한 막힘이 아니기 때문입니다. 설계 자체는 조심스럽습니다. 읽기는 용량 상한·타임아웃·canonical path로 cwd 밖 차단·실패 시 빈 값 처리가 있고, 결과는 cwd 키 캐시(최대 128, TTL 30초)입니다. src/config.tssrc/types/provider.ts에 optional 필드만 더하므로 types/config 분할 캠페인 때문에 닫아야 할 PR은 아닙니다.

지금 막힌 이유는 기능보다 게이트입니다. 아직 draft이고, src/server/auth-cors.tsprojectContext: "editor" 한 줄을 추가했다는 이유로 hygiene가 unsponsored_surfaceintake: hygiene-blocked입니다. 설정 UI에 노출할 필드를 등록하는 정상적인 한 줄이지만, 그 파일이 인증·설정 표면이라 메인테이너 스폰서(maintainer-sponsored) 없이는 머지 기차에 못 탑니다. 작성자 본문도 스폰서를 요청한 상태입니다.

설명과 코드가 어긋납니다. PR 본문은 스킬 경로를 skills/, .codex/skills/, .agents/skills/라고 적었고, docs도 taste.md만 뭉뚱그립니다. 실제 SKILL_ROOTS.commandcode/skills, .agents/skills, .pi/skills이고, taste는 .commandcode/taste/taste.md입니다. 켠 사용자가 Codex/루트 skills/만 만들어 두면 스킬이 비어 올라갑니다. docs-site providers 안내도 경로를 코드와 같게 써야 합니다.

보안은 opt-in이라 기본 위험은 낮습니다. 그래도 켜는 순간 워크스페이스 문서를 업스트림으로 보내므로, 팀 공유 설정에 "on"이 실수로 박히지 않게 설명이 분명해야 합니다. 캐시는 cwd 문자열만 키로 써서 같은 폴더를 쓰는 제공자끼리 내용을 공유합니다. 비밀 키가 아니라 로컬 파일이라 대체로 괜찮습니다.

라인 37-41 - SKILL_ROOTS가 PR 본문·요약의 skills/.codex/skills 설명과 다름. 문서·본문을 .commandcode/skills·.agents/skills·.pi/skills에 맞추거나, Codex 관례 경로를 정말 지원할 거면 코드를 바꿀 것
라인 196 - taste 실경로는 .commandcode/taste/taste.md인데 docs는 taste.md만 말해 루트에 파일을 두기 쉬움
경로 src/server/auth-cors.ts - projectContext: "editor" 추가가 unsponsored_surface. 스폰서 라벨이 머지 게이트
경로 src/config.ts / src/types/provider.ts - optional projectContext는 분할 캠페인과 충돌 없음. close-don't-rebase 대상 아님
경로 PR 상태 - draft + intake: hygiene-blocked. 체크리스트는 채워졌지만 게이트는 아직 DRAFT

메인테이너의 판단이 필요한 지점

  • auth-cors 한 줄 정책 등록을 스폰서해도 될 만큼 설정 표면 검토가 끝났는지
  • 스킬 루트를 Command Code 관례(.commandcode/.pi)에 둘지, PR 본문대로 Codex 관례(skills//.codex/skills)까지 넓힐지
  • 일곱 레인(L2–L7) 첫 구현 PR보다 먼저 넣을 가치가 있는지

너의 추천
지금은 머지하지 말 것. draft 유지. 문서·PR 본문의 스킬/taste 경로를 코드와 맞춘 뒤, 메인테이너가 표면 검토하고 maintainer-sponsored를 붙이면 그때 ready로 올리면 됩니다. 레인 막힘 PR이 있으면 그쪽을 먼저 보세요.

Reviewed 88c87a1. The opt-in/default-empty behavior is useful, but the finite enumeration claim is not enforced by listSkillDirs: the stopping condition is names.length >= scanBudget, reached only after a non-hidden directory with a valid SKILL.md is accepted. Hidden entries, regular files, and directories without SKILL.md never consume that budget. The new test contains 300 valid skill directories, so it cannot catch this case.

Count every visited directory entry against an independent scan budget before filtering, while retaining the separate selected-skill limit. Add a mixed/nonmatching-entry test which observes the iterator count, plus the existing valid-directory positive control. Keep timeout cleanup; a timeout is not a substitute for the documented work cap.

Also align docs/body with the actual paths: .commandcode/taste/taste.md, .commandcode/skills, .agents/skills, .pi/skills. Explain that currentWorkingDirectory() is the OCX process working directory, not automatically the caller's remote workspace. The feature sends those local contents upstream when enabled, so a sponsorship decision still requires that configuration boundary to be accepted. I have not applied a sponsorship label, enabled CI, or executed project file reads.

In `@docs-site/src/content/docs/guides/providers.md`:
- Around line 598-600: Update the documentation for command-code provider
projectContext to list the exact files and directories loaded:
.commandcode/taste/taste.md and SKILL.md files under .commandcode/skills,
.agents/skills, and .pi/skills. State that enabling projectContext sends the
collected workspace content to the configured Command Code endpoint, while
preserving the existing bounded, fail-soft, opt-in behavior.

In `@src/adapters/command-code-project-context.ts`:
- Line 339: Update readSkills to use one wall-clock deadline for the entire
skill-loading operation, rather than resetting timeoutMs for each directory
listing and read. Pass only the remaining time to each operation, stop
processing when the deadline expires, and preserve the existing collected.length
limit and readSkill flow.

In `@src/adapters/command-code.ts`:
- Around line 525-529: Add adapter-level coverage in the command-code provider
tests for buildRequest with projectContext omitted or off and with
projectContext set to "on"; parse the /alpha/generate request body and assert
that the top-level body.memory, body.taste, and body.skills contain the loaded
context for "on" and the empty sentinel for omitted/off, rather than checking
nested config fields.

In `@tests/providers/command-code-project-context.test.ts`:
- Line 590: Remove the direct pruneProjectContextCache call from the test setup
and delete the now-unused now variable, allowing loadCommandCodeProjectContext
insertions to exercise the cache capacity boundary independently.
- Around line 108-110: Update the resolved-name precedence test fixtures created
by writeSkill so .commandcode/skills, .agents/skills, and .pi/skills use
distinct directory names while retaining the same frontmatter skill name; this
ensures the test detects deduplication by resolved name rather than directory
name.

Addressed review comments on head a0a69ff8e rebased cleanly on latest dev (121405b53):

  • Scan budget on all visited entries: In src/adapters/command-code-project-context.ts, listSkillDirs now counts every visited directory entry against an independent scan budget before filtering.
  • Wall-clock deadline: Updated readSkills to enforce a single wall-clock deadline across sequential skill loading operations.
  • Mixed entry regression test: Added bounds mixed and nonmatching directory enumeration to the scan budget in tests/providers/command-code-project-context.test.ts.
  • Precedence test fixtures: Updated precedence test fixtures to use distinct directory names with identical frontmatter names to verify deduplication by resolved name.
  • Cache test setup: Removed manual cache pruning from the loader cache capacity test.
  • Adapter-level coverage: Added adapter-level tests in tests/providers/command-code-provider.test.ts asserting top-level request body context fields (memory, taste, skills) for omitted, "off", and "on".
  • Documentation alignment: Updated docs-site/src/content/docs/guides/providers.md to reflect actual paths (.commandcode/taste/taste.md, .commandcode/skills, .agents/skills, .pi/skills) and clarified that currentWorkingDirectory() is the local opencodex process working directory.
  • Verification: All 76 tests across tests/providers/command-code-project-context.test.ts and tests/providers/command-code-provider.test.ts and bun run typecheck pass cleanly.

Sponsored. Reviewed the restricted touch only: src/server/auth-cors.ts gains one row, projectContext: "editor".

projectContext is user-authored envelope text, not a credential, so editor is the right policy and nothing moves out of REDACTED_PROVIDER_FIELDS. No auth decision, no admission path, and no existing field changes classification.

This label covers the security boundary in MAINTAINERS.md only. The feature itself still needs ordinary review.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert distinct context values for the "on" case.

These assertions also accept the disabled sentinels: memory: "", taste: null, and skills: null. The test passes if buildRequest never calls loadCommandCodeProjectContext.

Set a known working-directory fixture or mock the loader. Then assert the exact memory, taste, and skills values.

As per path instructions, “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”
