Project Task

Maintain a compact task system in docs/task/ with deterministic status updates.

Hard Rules

1. Use English filenames only, even for Chinese content.
2. Keep one language per project/task file (follow user preference, otherwise follow existing project language).
3. Task index uses one-line entries only; all details go to detail files.
4. Claim before work; do not implement code before claim is complete.
5. Write status changes immediately; never defer.

Language Mode

• Content can be English or Chinese.
• Filenames stay English in all cases (index.md, PREFIX-NNN.md).
• Keep one language per project unless the user explicitly asks to switch.

Canonical Structure

docs/task/
├── index.md
└── PREFIX-NNN.md

• index.md: one-line status entries
• PREFIX-NNN.md: detail files (description, owner, dependencies, notes)

Task Formats

Index Entry

- [ ] [**PREFIX-001 Short imperative title**](PREFIX-001.md) `P1`

Index Entry (Chinese Content)

- [ ] [**PREFIX-001 简短祈使句标题**](PREFIX-001.md) `P1`

Detail File Template

# PREFIX-001 Short imperative title

- **priority**: P1
- **owner**: (unassigned)
- **createdAt**: YYYY-MM-DD HH:mm

## Description

What needs to be done, with context and acceptance criteria.

## ActiveForm

Present-continuous description for spinner display.

## Dependencies

- **blocked by**: (none)
- **blocks**: (none)

## Notes

(Implementation notes, progress logs, or related links.)

Detail File Template (Chinese Content)

# PREFIX-001 简短祈使句标题

- **status**: pending
- **priority**: P1
- **owner**: (未分配)
- **createdAt**: YYYY-MM-DD HH:mm

## 描述

需要做什么，包含上下文和验收标准。

## 进行时描述

进行中的现在进行时描述（用于 spinner 显示）。

## 依赖

## 笔记

（实现笔记、进度日志或相关链接。）

ID, Marker, and Status Rules

Task ID

• Format: PREFIX-NNN (uppercase prefix + zero-padded 3 digits)
• Sequence per prefix starts from 001
• Never reuse or renumber IDs

Status Markers

Allowed detail status values

• pending
• in_progress
• completed
• closed

Priority

• P0: blocking
• P1: high
• P2: medium
• P3: low

Claim-Before-Work (Multi-Agent Safety)

Before writing any implementation code:

1. Read docs/task/index.md.
2. If marker is [-], open detail file and check owner.
3. If owned by another agent, skip and pick another task.
4. Claim atomically:
   • Update index marker [ ] -> [-]
   • Update detail status -> in_progress and set owner
   • Call TaskUpdate(status: "in_progress", owner: "<agent>") if task tools are available
5. Start implementation only after all claim writes succeed.

On completion:

• Update index [-] -> [x]
• Update detail status -> completed
• Call TaskUpdate(status: "completed") if task tools are available

On close/won't do:

• Update index to [~]
• Update detail status -> closed and add reason in notes
• Call TaskUpdate(status: "deleted") if task tools are available

Sync Rules

Primary source is docs/task/ files.

• If TaskCreate/TaskUpdate tools are available, keep tool state synced with file state.
• If tools are unavailable, continue with file-only sync and mention that in updates.

Session checklist:

1. Session start: read docs/task/index.md and active detail files.
2. New task: create detail file first, then append index line.
3. Before work: complete Claim-Before-Work.
4. Session end: verify all statuses are persisted and update index header date.

Project Initialization

On first use in a repository:

1. Ensure CLAUDE.md has a ## Project Task section that references /ptask and claim-before-work.
2. Ensure AGENTS.md has the same section.
3. Ensure docs/task/index.md exists; initialize it if missing.

Recommended CLAUDE.md / AGENTS.md block:

## Project Task

Use the /ptask skill to manage all tasks.
- Read `docs/task/index.md` before starting work.
- Every feature/fix has a task entry.
- Use `PREFIX-NNN` IDs; never reuse IDs.
- Claim task before implementation: index + detail + task tool sync.
- Update status markers in place after progress/completion.

Chinese content version (filenames still English):

## Project Task

使用 /ptask 管理所有任务。
- 开始工作前先读 `docs/task/index.md`。
- 每个功能或修复都要有对应任务条目。
- 任务编号使用 `PREFIX-NNN`，禁止复用。
- 实现前必须先认领：索引 + 详情 + 任务工具状态同步。
- 进度和完成后原地更新状态标记。

Update Rules

• In index.md, only update checkbox markers; never delete historical lines.
• In detail files, update fields in place; do not delete existing sections.
• Append new tasks at the end of index.md.

Output Behavior

When reporting progress:

1. Summarize index changes.
2. List [-] and [ ] tasks.
3. List newly completed [x] tasks.

Keep updates concise and aligned with actual repository changes.
