verify-prd

verify-prd is a command for coding agents from alisunstar/OpenSunstar. It costs 0 tokens per session (339 once invoked), scanned A, original, Apache-2.0.

An early quality check for a product requirement document, or PRD—the document describing what should be built, why, and how success will be judged.

In plain words
What is it for?
It reads the change materials and project knowledge, evaluates the requirement input, and records problems that need clarification before work continues.
Why use it?
It exposes unclear goals, missing boundaries, unknown constraints, and untestable success criteria before analysis or coding begins.

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

verify-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 4d 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

/rd:verify-prd — 输入质量门禁

阶段 0:校验 PRD/需求输入质量,fail-fast 暴露早期问题。

先读规则

  1. .specs/<change-id>/ 已有产物(若有)
  2. knowledge/ROUTING.md 定位需求所属业务域
  3. knowledge/main/ 对应域的公共语境

执行

校验输入是否满足以下质量门槛:

  • 需求目标明确(做什么、为什么、成功标准)
  • 范围边界清晰(包含什么、不包含什么)
  • 关键约束识别(性能/兼容/安全/历史包袱)
  • 验收标准可测

何时澄清

  • 目标模糊或冲突 → 暂停,产出待澄清项
  • 范围缺失 → 暂停,要求补充

何时停止

  • 输入质量不达标 → 停止,不进入分析
  • 缺少关键约束 → 停止,要求补充

产物

  • .specs/<change-id>/CHANGE.md(需求输入摘要 + 质量评估 + 待澄清项)

人工确认

— 产出 CHANGE.md 后暂停,等人工确认质量达标后继续。

fail-fast 原则

能在 PRD 阶段暴露的问题,绝不拖到 requirement 或编码阶段。

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.

verify-prd is a command published in the GitHub repository alisunstar/OpenSunstar (40 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 339 tokens. 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.
