What it does

Prd Writing is an agent skill from itseffi/agentic-os. Write a structured PRD for high-risk, cross-team, or multi-sprint initiatives before implementation.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: Agentic personal OS to automate high-leverage workflows with Codex, Claude Code, Pi, OpenClaw and other coding agents/ runtime platforms. The licence is MIT.

When your agent uses it

Tasks that involve PRD writing

Example prompts

“/prd-writing”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Confirm PRD is needed
Gather required inputs
Produce PRD in required format
Quality checks before finalizing

What it can do on your machine

Read from SKILL.md and the folder at commit e54d0ac. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prd Writing loads about 754 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 182 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~28
When it runs · the whole SKILL.md, loaded when a task matches: ~754

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PRD Writing

Create clear, implementation-ready product requirements documents for initiatives that need alignment before coding.

The Process

Step 1: Confirm PRD is needed

Use PRD only if at least one is true:

cross-team dependency
multi-sprint scope
high-risk decision or expensive tradeoff
stakeholder alignment needed before build

If none apply, recommend execution-first flow (writing-plans -> tdd -> verification) instead.

Step 2: Gather required inputs

Collect:

product goal and target user
business context and constraints
known assumptions and risks
success criteria and timeline

State explicit assumptions when inputs are missing.

Step 3: Produce PRD in required format

Use this exact structure:

markdown

# [Product Name]

## About
[High-level overview of the product and goal.]

## Market Insights
[Market context, competitors, trends, and target users.]

## Problem
[Core user problem, pain points, and why existing solutions are insufficient.]

## Solution
[Proposed AI product solution and how it addresses the problem.]

## Feature Prioritization

| Feature | Reach | Impact | Confidence | Effort | RICE Score | Priority |
|---------|-------|--------|------------|--------|------------|----------|
|         |       |        |            |        |            |          |
|         |       |        |            |        |            |          |
|         |       |        |            |        |            |          |

## Requirements

**Functional Requirements:**
- FR1:
- FR2:
- FR3:

**AI/ML Model Requirements:**
- MR1:
- MR2:
- MR3:

**Non-Functional Requirements:**
- NFR1:
- NFR2:
- NFR3:

## Challenges
[Key product, technical, data, and go-to-market challenges.]

## Positioning

| Use Case | Target User | Key Benefit | Differentiator |
|----------|-------------|-------------|----------------|
|          |             |             |                |
|          |             |             |                |
|          |             |             |                |

## Metrics
[Success metrics and north star metric.]

## Rollout Plan

- **Stakeholders & Communication**
  - [Stakeholder groups and communication plan]

- **Roll-out Strategy**
  - [Launch phases, gating criteria, and post-GA plan]

Step 4: Quality checks before finalizing

Ensure:

no placeholder fields remain
RICE rows are populated and prioritized
metrics include baseline, target, and timeframe
rollout includes phases and gating criteria
top risks are explicit

Output

Final PRD in the required structure
A short assumptions list
Open questions/blockers list

When to Use

Use this skill when the task directly matches the workflow described above.

When Not to Use

Do not use this skill when the request is unrelated, low-stakes, or better handled by a simpler direct response.
