plan

Analyze the current repository and write a detailed PLAN-{build_lane}-GNN.md for implementation work. Also writes the CODE_REVIEW-{review_lane}-GNN.md stub that the implementing agent will fill in after coding. Use for any feature, refactor, bug fix, or follow-up fix that should enter the plan-code-review loop. A separate implementing agent, or the same agent in an implementation pass, reads the plan file and does the coding. The code-review skill archives both files after review and moves PASS tasks under agent-task/archive/YYYY/MM/.

Plan

Purpose

Create the planning artifacts for the implementation loop:

plan skill -> PLAN-{build_lane}-GNN.md + CODE_REVIEW-{review_lane}-GNN.md stub
implementation -> code changes + filled CODE_REVIEW-{review_lane}-GNN.md
code-review skill -> verdict + archive, complete.log, and PASS task-directory archive move or new follow-up plan/review files

Workflow Contract

This skill intentionally uses routed active files under an active task directory as the state protocol. Do not change this directory or filename contract unless the paired code-review skill is updated together.

Task path terms:

• {task_group} is the top-level work category under agent-task/, using a short snake_case name such as refactoring.
• {subtask_dir} is used only for split work and follows the existing indexed directory naming rules below, such as 01_core or 02+01_db.
• {subtask_name} is the short snake_case name after the index or dependency prefix inside {subtask_dir}.
• {task_name} in headers and templates means the active task path relative to agent-task/: either {task_group} for a single-plan task or {task_group}/{subtask_dir} for a split subtask.
• A single-plan task stores active files directly under agent-task/{task_group}/.
• Split work stores active files under agent-task/{task_group}/{subtask_dir}/; the parent agent-task/{task_group}/ is only the grouping folder and must not contain active plan/review files.

Filename rules:

• Plan file: PLAN-{build_lane}-GNN.md
• Review stub: CODE_REVIEW-{review_lane}-GNN.md
• {lane} is only local or cloud; never put model names in filenames.
• GNN is a two-digit capability grade from G01 to G10; the runtime maps lane+grade to current models externally.

Role boundary rules:

• Implementing agents fill implementation-owned CODE_REVIEW-*-G??.md sections, keep active files in place, and report ready for review.
• Finalization (코드리뷰 결과, log rename, complete.log, archive moves, review-only checklist) is code-review-skill only.

Split decision policy:

• Default to multiple subtask directories under one task group. Before writing any plan, decide whether the work has smaller independently reviewable implementation units.
• If there is any natural dependency boundary, ownership boundary, subsystem boundary, API-vs-call-site phase, test strategy split, or independently reviewable risk, write multiple subtask directories under one task group.
• A single plan is an exception. Use one only when all of these are true: the work is one coherent implementation unit, it has one primary ownership boundary, it has no prerequisite subtask, splitting would create artificial coordination overhead, and the whole change remains easy to review at once.
• When uncertain, split. Do not choose a single plan merely because it is shorter to write.
• Record the split decision in the plan. For a single plan, explicitly state why each applicable split boundary does not require a separate task. For multi-plan output, list the shared {task_group}, each sibling {subtask_dir}, and its dependency relationship.

Split gates:

• Split when the work combines shared API/foundation changes with broad call-site rollout. Put the API/foundation in an earlier task and the rollout in dependent task(s).
• Split when the work touches multiple domains or ownership boundaries, unless the change is purely mechanical and trivially reviewable.
• Split when different parts can be verified with different focused tests or have different risk profiles.
• Split when a likely failure in one part would force rewriting unrelated parts of the plan.
• Split when one part can produce a useful complete.log before another part starts.

Task directory naming rules:

• A single-plan task uses agent-task/{task_group}/ with a short snake_case category name, e.g. agent-task/refactoring/.
• When split gates require decomposition, create one shared category folder and multiple subtask directories under it. Each subtask directory owns exactly one normal active plan file and one normal active review stub.
• Multi-plan output is a set of independent PLAN-{build_lane}-GNN.md + CODE_REVIEW-{review_lane}-GNN.md pairs across agent-task/{task_group}/{subtask_dir}/ folders, not multiple plan files inside one folder.
• Multi-plan subtask directory names must start with a stable two-digit task index. The index must increase across sibling subtask directories for sorting, but it is not a serial execution dependency.
• Use NN_{subtask_name} for a task with no runtime dependencies, e.g. 01_core, 04_docs, 05_ui.
• Use NN+PP[,QQ...]_{subtask_name} for a task that depends on earlier task indices, e.g. 02+01_db, 03+01,02_api, 06+05_integration.
• Valid independent pattern: ^[0-9]{2}_[a-z0-9_]+$.
• Valid dependent pattern: ^[0-9]{2}\+[0-9]{2}(,[0-9]{2})*_[a-z0-9_]+$.
• NN, PP, and QQ are two-digit indices. Every predecessor index after + must be lower than NN and must refer to a sibling multi-plan subtask directory under the same {task_group}.
• The first _ after the index or dependency list starts {subtask_name}. {subtask_name} stays short snake_case and may contain additional underscores.
• Runtime scheduling reads only the {subtask_dir} name: _ means depends_on=[]; + means depends_on is the comma-separated index list between + and the first _.
• Subtask directory names are the source of truth for runtime dependencies. Do not hide extra dependencies only in the plan body, and do not create a bare NN+{subtask_name} without predecessor indices.
• Example: split a refactoring common core plus two app integrations under agent-task/refactoring/ as 01_core, 02+01_edge_integration, 03+01_node_integration. Both integrations depend only on 01_core and may run in parallel after 01_core has complete.log.
• Example: split three sequential tasks under one task group as 01_schema, 02+01_migration, 03+02_api.
• Example: split independent docs/UI plus an integration under one task group as 01_core, 02+01_db, 03+02_api, 04_docs, 05_ui, 06+05_integration; 01_core, 04_docs, and 05_ui can start together, and 06+05_integration waits only for 05_ui.
• Preserve task group and subtask directory names verbatim; do not normalize, reinterpret, or choose execution order by agent judgment.

Routing rules:

• Build defaults to local when the plan is explicit, tests are runnable, and failure is review-detectable.
• Use cloud for weak tests, broad API/call-site impact, ambiguity, storage/concurrency/protocol/auth risk, or prior local failure.
• Use cloud-G07 or higher for terminal-agent work: shell/CLI workflow implementation, bin script orchestration, process control, stdout/stderr parsing, exit-status contracts, long-running command diagnosis, or terminal benchmark-style tasks. Merely running deterministic tests such as go test does not make a task terminal-agent work.
• Use cloud-G07 or higher when acceptance depends on a real interactive external tool, TUI, PTY, browser, screen repaint/cursor stream, or bin-level smoke output. This is mandatory when unit tests pass but the real smoke/integration command fails.
• Use cloud-G07 or higher when a prior review found verification trust failure, reconstructed command output, or claimed stdout/stderr that does not match a rerun.
• Keep high-risk design judgment on cloud with a higher grade; the runtime may map cloud-GNN to frontier-class models.
• Review may be local for narrow/low-risk checks and cloud for multi-file/API/test-meaning reviews, security/auth, storage/migration, concurrency, protocol/schema, cross-domain, or repeated Required issues.
• Raise GNN with scope, ambiguity, missing tests, irreversible behavior, and blast radius; keep grade model-independent.

Directory states:

State	Meaning
PLAN-*-G??.md only	Invalid; plan skill always writes both active files
PLAN-*-G??.md + CODE_REVIEW-*-G??.md stub	Implementation is pending/in progress
PLAN-*-G??.md + filled CODE_REVIEW-*-G??.md	Ready for code-review skill
complete.log + *.log files	Task complete (PASS), before final task-directory archive move
agent-task/archive/YYYY/MM/{task_name}/complete.log + *.log files	Archived completed task path (PASS); not active
Only *.log files (no complete.log)	Task terminated mid-loop or abandoned

Step 1 - Determine Task

If the user names the task explicitly, use that task group or task path.

Otherwise, find active plan files with both globs, excluding agent-task/archive/**:

• agent-task/*/PLAN-*-G??.md
• agent-task/*/*/PLAN-*-G??.md

Result	Action
Exactly one	Continue that task
None	Create a new task only for a feature/refactor/fix/follow-up that belongs in this workflow
Multiple	If the user/runtime named a task group, task path, or subtask directory that identifies exactly one active plan, use it. Otherwise list paths and ask which task to use; do not choose by agent judgment.

The routed plan file is the loop entry point. A missing active plan normally means only that no plan has been started for a new task; do not create task files for casual analysis, status, or review requests unless the user explicitly asks for a plan.

로드맵 게이트:

• agent-ops/roadmap/current.md가 있으면 구현 계획 파일을 만들기 전에 읽고, 사용자 요청, 브랜치, 변경 경로를 기준으로 관련 Milestone을 선택한다.
• 선택한 Milestone을 한 번 읽는다. 구현 잠금 섹션이 없거나 상태가 잠금이면 PLAN-*-G??.md, CODE_REVIEW-*-G??.md를 만들지 않고 file/API/package 수준의 구현 단계도 작성하지 않는다.
• "진행", "그냥 구현", "계획 작성" 같은 사용자 지시는 Milestone 잠금을 해제하지 않는다. 구현 잠금이 없거나 잠긴 Milestone을 보고하고, 먼저 roadmap update 흐름으로 Milestone 구체화 업데이트 또는 잠금 해제를 요청하게 한다.
• roadmap/current 파일이 없으면 기존 task routing 규칙대로 진행한다.

Use short snake_case task group names, e.g. api_refactor.

Before choosing plan files or task directory names, apply the split decision policy above. When the policy allows a single plan, write active files directly under agent-task/{task_group}/ and record the exception rationale. When the policy requires multiple plans, choose one shared {task_group} and {subtask_dir} names using the task directory naming rules above. Do not put multiple active plan files in one active task directory, and do not mix split subtask directories with active plan/review files directly in the parent task group.

Step 2 - Analyze Before Writing

Complete all items below before creating any files. Work through them in order; do not proceed to the next step until every checkbox is done.

• Read all source files in full — read every source file the change will touch, whole file. No partial reads.
• Read all test files in full — read every test file that exercises the changed behavior.
• Assess test coverage — for each behavior change, explicitly record whether existing tests cover it.
• Assess split boundaries first — identify dependency boundaries, ownership boundaries, API-vs-call-site phases, test strategy splits, risk profile splits, and independently verifiable subwork before selecting plan files. If any split gate applies or the decision is uncertain, write multiple subtask directories under one task group instead of one plan.
• Grep all symbol references — for any renamed or removed symbol, find every call site and import chain.
• Check dependency manifests — before adding any new package, verify its presence in go.mod / package manifest.
• Pre-check compile issues — identify missing interface implementations, type mismatches, and broken imports.
• Verify verification commands — confirm that the final verification commands actually run in this repository layout.
• Stabilize fragile verification — for search or generated-output checks, choose deterministic commands up front, such as rg --sort path, and decide whether cached test output is acceptable or -count=1 is required.

Step 3 - Determine GXX Grade

GXX is an output of analysis, not an input. Determine lane and grade only after Step 2 is fully complete.

• Assess change scope — count affected files, interface impact, and call-site count.
• Check risk factors — mark any that apply: concurrency, storage/migration, protocol/schema, auth, irreversible behavior.
• Evaluate test confidence — judge whether existing tests sufficiently verify the changed behavior.
• Decide lane — use local if the plan is explicit and tests are sufficient; use cloud if any of the following apply:
  • Tests are weak or do not cover the changed behavior
  • Broad API/call-site impact
  • Concurrency, storage, protocol, or auth risk
  • Prior local build failure on this task
  • Terminal-agent work: shell/CLI workflow implementation, bin script orchestration, process control, stdout/stderr parsing, exit-status contracts, long-running command diagnosis, or terminal benchmark-style tasks
  • Real bin/smoke/integration verification failed after unit tests passed
  • Interactive TUI/PTY/browser/external CLI automation or screen-rendered output is part of the success condition
  • A prior review marked verification trust Fail/Warn because recorded command output did not match a rerun
• Decide GNN — assign a higher grade as scope, ambiguity, irreversibility, and blast radius increase. Grade is complexity-based, not model-name-based.

Step 4 - Archive Existing Active Files

Before writing new active files for the chosen active task directory:

• Count existing agent-task/{task_name}/plan_*.log; call it N. If PLAN-*-G??.md exists in that same directory, rename PLAN-{build_lane}-GNN.md to plan_{build_lane}_GNN_N.log.
• Count existing agent-task/{task_name}/code_review_*.log; call it M. If CODE_REVIEW-*-G??.md exists in that same directory, rename CODE_REVIEW-{review_lane}-GNN.md to code_review_{review_lane}_GNN_M.log.

The new plan number is the count of plan_*.log after archiving.

Step 5 - Write Plan File

Header line must be exactly:

<!-- task={task_name} plan={N} tag={TAG} -->

Required sections:

• Title.
• 이 파일을 읽는 구현 에이전트에게: warn that filling implementation-owned CODE_REVIEW-*-G??.md sections is mandatory. Tell the implementer to run verification, fill actual notes/output, keep active files in place, and report ready for review; finalization is code-review-skill only.
• 배경: 2-4 sentences explaining why the work is needed.
• 분석 결과: record the findings from Step 2 and Step 3. This section is the written output of the analysis — not a summary, but the actual findings that justify the plan's scope and decisions. Must include all of the following subsections:
  • 읽은 파일: list every source and test file read during analysis, with path.
  • 테스트 커버리지 공백: list each behavior change and whether existing tests cover it; explicitly note gaps.
  • 심볼 참조: list renamed/removed symbols and every call site found, or state "none" if no symbols were changed.
  • 분할 판단: state that the split decision policy was evaluated before choosing plan files. For a single plan, explain why each relevant split gate does not apply and why single-plan coordination is safer than splitting. For multi-plan output, list the shared task group plus each sibling subtask directory and dependency relationship.
  • 범위 결정 근거: state which files or areas were explicitly excluded from this change and why. This is the boundary justification — the implementing agent must not silently expand scope beyond what is recorded here.
  • 빌드 등급: state the decided lane and GNN grade with a one-line rationale.
• 구현 체크리스트: a top-level checklist the implementing agent must follow while coding. Include one item per plan item, one item for all intermediate/final verification, and make the final item exactly: - [ ] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다. 이 항목이 완료되기 전에는 구현이 완료된 것이 아니다. Copy this checklist into the review stub's 구현 체크리스트 section with the same item text and order.
• One item per change: ### [TAG-1] Title, TAG-2, etc.
• 수정 파일 요약: table mapping files to item ids.
• 최종 검증: runnable commands and expected outcome. Commands must be exact and deterministic enough for the reviewer to rerun; use stable ordering for searches and state whether cached test output is acceptable. The final line of this section must read exactly — "모든 코드 변경 완료 후 반드시 CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 채운다. 이 파일 작성이 구현의 마지막 단계다."

Each plan item must include:

• 문제: concrete problem with file:line references.
• 해결 방법: exact approach and before/after code block for non-trivial changes.
• 수정 파일 및 체크리스트: exhaustive file-level checklist.
• 테스트 작성: explicit write/skip decision. If writing tests, include path, test name, assertion goal, and fixtures. If skipping, justify.
• 중간 검증: runnable commands and expected result.

Include 의존 관계 및 구현 순서 only when order matters.

For split multi-plan work, the {subtask_dir} directory name is the runtime source of truth. If a plan has a NN+PP[,QQ...]_... subtask directory name, 의존 관계 및 구현 순서 must echo the decoded predecessor subtask directories under the same task group that must produce complete.log before implementation starts, and it must not add dependencies that are absent from the directory name.

Quality rules:

• Exact line numbers in every Before snippet.
• Use the language's required override annotation/keyword wherever an abstract method is implemented.
• Include full import statements for new packages.
• List all call sites for renamed/removed symbols.
• Never write "add tests as needed"; decide up front.
• Do not cite files you did not read.
• Be concise. Write the minimum words needed to convey the decision or fact. No preamble, no restatement of context already in the plan, no closing summaries.

Test policy:

Change	Test requirement
Bug fix	Regression test required
New public API	Normal + boundary tests required
API rename	Existing test call-site updates usually enough
Internal refactor	Existing tests may be enough
Concurrency logic	Race/ordering test recommended

Verification fidelity rules:

• Plan verification commands are a contract. The implementing agent must run them exactly as written.
• If a command must be changed, the implementing agent must record the replacement command and reason in 계획 대비 변경 사항, then paste the replacement command's actual stdout/stderr.
• Before claiming a tool is unavailable, run and record command -v <tool> or the project-equivalent check.
• Do not download, generate, or leave verification tools inside the repository. Temporary tools belong outside the repo, such as under /tmp, and must not become task artifacts.
• For search commands whose output order may vary, specify deterministic options in the plan, for example rg --sort path.
• 검증 결과 must contain actual stdout/stderr, not summarized or reconstructed output. If output is too long, record the saved output file path and the exact command used to create it.
• If the plan's pass condition says all leftovers must be intentional exceptions, any 변경 필요 item forces FAIL until resolved or explicitly reclassified with evidence.
• Decide in the plan whether Go test cache output is acceptable. If fresh execution matters, use go test -count=1 ....

Step 6 - Write Review Stub

Use the template below exactly. Fill {…} placeholders from the plan; everything else is fixed and must not be changed by the implementing agent.

<!-- task={task_name} plan={N} tag={TAG} -->
