prd-writer

prd-writer is a skill for Claude Code from Dokkabei97/forged-claude-code. It costs 56 tokens per session (1,294 once invoked), scanned A, original, MIT.

A lightweight product requirements document guide. A PRD is a short specification that explains what a product or feature should do, why it matters, and how success will be measured.

In plain words
What is it for?
Use it to plan new features, prepare for sprint planning, define hypotheses and metrics, and record risks or edge cases.
Why use it?
It gives a team a shared description of the problem, proposed solution, scope, evidence, and success measures before development 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

prd-writer 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 7d 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 Writer - Lightweight Product Requirements Document

Overview

Creates startup-appropriate PRDs — structured enough to align teams, lean enough to not slow you down. A good PRD answers "what and why", not "how".


1. When to Apply

Trigger Behavior
New feature planning Generate full PRD template
"write PRD", "feature spec" Guided PRD creation workflow
Before sprint planning Quick PRD for prioritized features

2. PRD Template

# PRD: [Feature Name]

> **Status**: Draft | In Review | Approved | In Development
> **Author**: [Name]
> **Date**: [YYYY-MM-DD]
> **Stakeholders**: [Names/Roles]

---

## 1. Problem Statement
[1-2 paragraphs. What problem are we solving? Who has this problem? How do they solve it today?]

**Evidence:**
- [User interview quote / data point / support ticket pattern]
- [Market research / competitor analysis finding]

## 2. Hypothesis
> If we [build X], then [target users] will [achieve Y],
> which we'll measure by [metric Z].

## 3. Success Metrics

| Metric | Current | Target | Measurement Method |
|--------|---------|--------|--------------------|
| Primary KPI | N/A or baseline | [target] | [how to measure] |
| Secondary KPI | N/A or baseline | [target] | [how to measure] |
| Guardrail Metric | [baseline] | [should not decrease] | [how to measure] |

## 4. Scope

### In Scope (MVP)
- [ ] [Core feature 1 — essential for value delivery]
- [ ] [Core feature 2 — essential for value delivery]
- [ ] [Core feature 3 — essential for value delivery]

### Out of Scope (Future)
- [Nice-to-have 1 — why deferred]
- [Nice-to-have 2 — why deferred]

### Non-Goals
- [What this feature explicitly will NOT do]

## 5. User Stories

### Primary Flow
> As a [user type], I want to [action], so that [benefit].

**Acceptance Criteria:**
- Given [context], when [action], then [result]
- Given [context], when [action], then [result]

### Secondary Flows
[Additional user stories as needed]

## 6. Design Considerations
- [UX principle or constraint]
- [Accessibility requirement]
- [Mobile/responsive considerations]

## 7. Technical Considerations
- [API changes needed]
- [Database schema impact]
- [Third-party integrations]
- [Performance requirements]

## 8. Edge Cases & Risks

| Edge Case | Expected Behavior |
|-----------|-------------------|
| [Edge case 1] | [How system should handle it] |
| [Edge case 2] | [How system should handle it] |

| Risk | Likelihood | Impact | Mitigation |
|------|------------|--------|------------|
| [Risk 1] | H/M/L | H/M/L | [Plan] |

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.
