A project-start command that turns a requirements document, product requirements document (PRD), specification, or detailed task description into an implementation plan.

Use it to begin work from a PRD, design document, specification, or detailed feature list.

It gives the agent a structured starting point when the desired work has already been written down. It is intended for clear requirements rather than an empty project idea.

prd — Command for Claude Code by sdsrss/gsd-lite

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/sdsrss/gsd-lite

Made for: Claude Code.

Or install gsd, the plugin that ships this one along with the rest of its 6 commands, 4 agents, 3 hooks.

Per session 25 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 857 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00025	$0.00857
Opus 5.5	$0.00010	$0.00343
Sonnet 5.5	$0.00005	$0.00171
Haiku 4.5	$0.00003	$0.00086

Measured 5d ago against content hash c07dc7b21526, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

prd 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 5d 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.

What it actually says

STEP 0 — 已有项目检测

调用 health 工具（MCP tool 名称: health）。如果返回 state_exists=true 且项目未完成/未失败:

告知用户: "检测到进行中的 GSD 项目。"
显示当前项目状态 (项目名、当前阶段、workflow_mode)
提供选项:
- (a) 恢复现有项目 → 转到 /gsd:resume
- (b) 覆盖并重新开始 → 继续 STEP 1（现有 state.json 将被覆盖：后续 state-init 必须带 force: true，否则会返回 STATE_EXISTS 且什么也不做）
- (c) 取消
等待用户选择后再继续

如果无 state 或项目已完成/已失败 → 直接进入 STEP 1。

STEP 1: 解析输入

判断 $ARGUMENTS 的类型:

如果是文件路径 (包含 / 或 . 且文件存在):

使用 Read 工具读取文件内容
如果文件不存在:
- 告知用户文件不存在
- 提示常见原因: 路径拼写错误、当前工作目录不正确
- 建议: "请确认文件路径，或使用绝对路径重试。需要我帮你查找文件吗？"
- 停止

如果是文本描述:

直接作为需求描述使用

STEP 2: 分析代码库

使用 Glob/Grep/Read 分析代码库中与需求相关的部分
识别: 已有代码结构、技术栈、现有约定
目的: 让后续计划能与现有代码库无缝衔接

STEP 3: 提取关键需求点

从输入内容中提取所有关键需求点
整理为结构化列表
向用户确认理解是否正确:
- "以下是我从需求中提取的关键点，请确认:"
- 逐条列出，标注优先级

STEP 4: 提出补充问题

基于需求分析，识别模糊点和缺失信息
提出补充问题，每个问题提供选项:
- 标识推荐选项
- 允许用户自定义回答
使用提问技巧 (如可用): 调用 health 工具取 docs.references, Read <docs.references>/questioning.md
用户回答后，可适当追问直到需求清晰

调用 health 工具取 docs.workflows，Read <docs.workflows>/execution-flow.md，严格按照其中 STEP 5-12 执行。

<orchestrator_rules>

编排器纪律

只有编排器写 state.json，子代理不直接写
所有摘要/提示在展示时从 canonical fields 推导，不持久化 derived fields
子代理返回结构化 JSON，不解析自然语言
上下文 < 35% → 保存状态 + workflow_mode = awaiting_clear + 停止执行 </orchestrator_rules>

Changes

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.

prd is a command published in the GitHub repository sdsrss/gsd-lite (4 stars, last pushed 2d ago), licensed MIT. It adds 25 tokens to every session and 857 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
