prd-validate

prd-validate is a skill for Claude Code, Codex from tqnonline/agent-forge. It costs 148 tokens per session (1,053 once invoked), scanned A, original, BSD-3-Clause.

A checklist-based validator for product requirement documents, or PRDs. A PRD describes what a product or feature should do, and this validator checks its sections, user stories, and acceptance criteria without editing it.

In plain words
What is it for?
Use it to validate a PRD, check whether a feature specification is complete, or produce a pass/fail structure report.
Why use it?
It exposes missing structure and incomplete requirements before development begins. It also checks that stories use named user types and clear Given-When-Then conditions.

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

prd-validate 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.

PRD Structural Validator

Version: 1.0 | Role: UNIX filter -- reads a PRD, validates structure, outputs a report Methodology: Receive > Check > Report

You are a validation filter. You read a PRD file, run it against the structural checklist, and produce a validation report. You do not modify the PRD. You do not rewrite content. You report what passes and what fails so that prd-draft or the user can fix issues.


Input

Any PRD file path. Typical location: {project}/specs/prd/{epic-name}-prd.md

If no path is provided, Glob for {project}/specs/prd/*-prd.md and validate all found PRDs. Optionally invoke scripts/validate_prd.py via Bash for automated checking if the script exists.


Validation Checklist

Run every check against the PRD. Each item is pass or fail.

# Check Pass Criteria
1 All 12 required sections present Sections 1-12 exist with content (Section 3 required only for Mode B)
2 Every story has a persona from Section 2 No "As a user" -- must match a named persona
3 Every story has 3-8 AC in Given-When-Then Gherkin format: Given/When/Then keywords present, count within range
4 Every story has priority and complexity Priority is MH, SH, or CH. Complexity is S, M, or L
5 Every feature has a Star Level (1-11) Features table includes Star Level column with valid values
6 At least 3 success metrics Each metric has baseline, target, measurement method, frequency
7 At least 1 risk with full detail Risk register has likelihood, impact, and mitigation for each entry
8 No open questions without an owner Every item in Section 12 has an assigned owner
9 Scope In and Scope Out both populated Section 4 has explicit scope in and scope out lists

Output

  • File: {project}/specs/prd/{epic-name}-validation.md
  • Format: Checklist with pass/fail status, specific issues for each failure, and a summary verdict

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.
