t-task

A task-planning skill that turns completed technical design documents into ordered phases of implementation work. It uses the design, requirements, decisions, and testing information as its input.

In plain words
What is it for?
Use it to create phased task plans for frontend, backend, Flutter, and cross-platform features, including dependencies, affected files, and acceptance steps.
Why use it?
It exposes missing decisions and unclear boundaries before implementation begins. It also keeps each task tied to its design and verification requirements.

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

t-task 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

任务规划生成

运行时边界统一参考:${CLAUDE_PLUGIN_ROOT}/protocols/runtime-boundaries.md 需求来源边界统一参考:${CLAUDE_PLUGIN_ROOT}/protocols/requirement-source-contract.md 决策连续性和用户决策暴露统一参考:${CLAUDE_PLUGIN_ROOT}/protocols/decision-continuity-contract.md 设计生成状态统一参考:${CLAUDE_PLUGIN_ROOT}/protocols/design-state-contract.md

任务拆分必须服务于边界清楚、验证闭环明确的执行;如果设计文档、guide 或 protocol 冲突,停止并说明冲突。

影响规划方向的缺口必须通过 AskUserQuestion 解决,不得把问题写成 P0/P1、假设或 handoff 后继续生成任务。

Input Contract

上游输入(来自 /t-design 产出):

  • .ai/design/[feature].md — 设计主文档(必须存在)
    • 必须包含:目标、范围、交付端范围、跨端契约摘要、测试与验收汇总、文件影响范围全量汇总
    • 应包含:现有实现分析概览、用户故事/PRD/技术预研引用、Decision Trace
    • 纯技术方案设计可只包含技术预研引用,但必须声明不涉及业务逻辑、产品规则、用户可见流程或验收目标变动
  • .ai/design/[feature]/backend.md.ai/design/[feature]/frontend.md.ai/design/[feature]/flutter.md — 分端设计文档;主文档 §4.2 标记适用时必须存在,生成对应 phase 时必须读取(API 契约、数据库设计等分端细节以分端文档为准)
  • .ai/design/[feature]/.state.json — 设计生成状态;存在时必须为 complete
  • .ai/decision-log/[feature].md — 跨阶段决策账本(存在时必须读取;本阶段不得采用 Superseded Decision)

可选输入:

  • .ai/task/[feature]/.state.json — 已有任务状态(增量生成时)
  • docs/prd/**/*.md — PRD 文档
  • .ai/user-stories/**/*.md — draft 用户故事
  • docs/user-stories/**/*.md — 已发布用户故事
  • .ai/tech-research/**/*.md — 技术预研报告
  • ${CLAUDE_PLUGIN_ROOT}/guides/ — 开发规范

Output Contract

下游产出:

  • .ai/task/[feature]/.state.json — 任务状态文件,包含 phase/slot/item 层级状态
  • .ai/task/[feature]/<phase>/index.md — 阶段总览,包含当前 phase 的 Decision Trace
  • .ai/task/[feature]/<phase>/<slot>.md — Slot manifest(导航与执行顺序)
  • .ai/task/[feature]/<phase>/<slot>/<ITEM-ID>-*.md — 可执行的 item 文件

状态结构、item 字段、slot 顺序、测试集中执行和 backend/test 特殊字段统一参考:

  • ${CLAUDE_PLUGIN_ROOT}/protocols/task-state-contract.md
  • ${CLAUDE_PLUGIN_ROOT}/protocols/task-phase-execution.md

Purpose

  • .ai/design/[feature].md 生成 .ai/task/[feature]/ 任务目录和 .state.json
  • 固定使用 phase -> slot -> item 模型。
  • 生成串行执行的 item 文件,而不是把 manifest 当执行输入。

Args

参数 说明
[feature] 功能名(必填)
--phase <backend|frontend|miniapp|flutter|web-demo|flutter-demo> 指定阶段生成;未指定时默认选择第一个 active phase

What this file has done since we first saw it

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.

t-task is a skill published in the GitHub repository timzaak/web-dev-skills (69 stars, last pushed 4d ago), licensed Apache-2.0. It adds 17 tokens to every session and 3,521 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 2026-08-30.
