Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Execute the implementation planning workflow using the plan template to generate design artifacts.Key capabilities
- →Load persona and context for initialization.
- →Outline and research the project in Phase 0.
- →Perform UI/UX design if required in Phase 0.5.
- →Conduct design and contract definition in Phase 1.
- →Generate a file list and validate acceptance criteria in Post-Design.
- →Report the completion of the planning process.
How it works
The skill executes a phased implementation planning workflow, reading specific markdown files for each phase (setup, research, UI/UX design, design/contract, post-design, finish) and incrementally writing content to an `IMPL_PLAN`.
Inputs & outputs
When to use speckit.plan
- →Create an implementation plan for a new feature
- →Break down a project into concrete tasks
- →Generate a technical checklist
- →Validate feature specifications

speckit.plan — 实现方案设计
从功能规格出发，经过研究、UI/UX 设计（条件）、技术设计产出实现方案。
阶段清单
| 阶段 | 文件 | 职责 |
|---|---|---|
| 初始化 | .specify/phases/plan/setup.md | 加载 persona + context、架构评估、技能加载 |
| Phase 0 | .specify/phases/plan/phase-0.md | 大纲与研究 |
| Phase 0.5 | .specify/phases/plan/phase-05.md | UI/UX 设计（条件执行：仅当 spec 含 UI/UX 需求时） |
| Phase 1 | .specify/phases/plan/phase-1.md | 设计与合约 |
| Post-Design | .specify/phases/plan/post-design.md | 文件清单 + AC 验证设计 |
| 完成 | .specify/phases/plan/finish.md | 报告 |
执行协议
CRITICAL: 禁止一次性读取所有阶段文件。仅在即将执行该阶段时 Read 对应文件。
- Read
.specify/phases/plan/setup.md→ 执行初始化 - 初始化完成后 Read
phase-0.md→ 执行 Phase 0 - Phase 0 完成后：
- 如 FEATURE_SPEC 含 UI/UX Requirements → Read
phase-05.md - 否则 → 直接 Read
phase-1.md
- 如 FEATURE_SPEC 含 UI/UX Requirements → Read
- Phase 1 完成后 Read
post-design.md→ 文件清单 + AC 验证 - Post-Design 完成后 Read
finish.md→ 报告
增量写入
每个阶段完成后立即将内容写入 IMPL_PLAN 对应章节（增量持久化）。
全局规则
- 所有非代码内容使用简体中文
- Use absolute paths
- ERROR on gate failures or unresolved clarifications
When not to use it
- →When the task does not involve implementation planning or generating design artifacts.
- →When all phase files are read at once instead of incrementally.
- →When the project does not require a structured planning workflow.
Limitations
- →The skill requires incremental reading of phase files.
- →The skill uses specific markdown files for each phase.
- →The skill enforces non-code content in Simplified Chinese.
How it compares
This skill provides a structured, phased approach to implementation planning, ensuring specific artifacts are generated at each stage, unlike an unstructured planning process.
