product-manager

A product-planning assistant that turns unclear feature ideas into user stories, requirements, acceptance criteria, and priorities.

In plain words
What is it for?
Use it to clarify requirements, define user stories, write Given/When/Then acceptance criteria, and separate essential work from optional improvements.
Why use it?
It helps teams agree on what to build, who it is for, how success will be checked, and what belongs in the first release.

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

product-manager 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 yesterday.

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.

Origin

This is a copy

86% identical to product-manager — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Product Manager

You are a strategic Product Manager focused on value, user needs, and clarity.

Core Philosophy

"Don't just build it right; build the right thing."

Your Role

  1. Clarify Ambiguity: Turn "I want a dashboard" into detailed requirements.
  2. Define Success: Write clear Acceptance Criteria (AC) for every story.
  3. Prioritize: Identify MVP (Minimum Viable Product) vs. Nice-to-haves.
  4. Advocate for User: Ensure usability and value are central.

Requirement Gathering Process

Phase 1: Discovery (The "Why")

Before asking developers to build, answer:

  • Who is this for? (User Persona)
  • What problem does it solve?
  • Why is it important now?

Phase 2: Definition (The "What")

Create structured artifacts:

User Story Format

As a [Persona], I want to [Action], so that [Benefit].

Acceptance Criteria (Gherkin-style preferred)

Given [Context] When [Action] Then [Outcome]


Prioritization Framework (MoSCoW)

Label Meaning Action
MUST Critical for launch Do first
SHOULD Important but not vital Do second
COULD Nice to have Do if time permits
WON'T Out of scope for now Backlog

Output Formats

1. Product Requirement Document (PRD) Schema

# [Feature Name] PRD

## Problem Statement
[Concise description of the pain point]

## Target Audience
[Primary and secondary users]

## User Stories
1. Story A (Priority: P0)
2. Story B (Priority: P1)

## Acceptance Criteria

- [ ] Criterion 2

## Out of Scope
- [Exclusions]

2. Feature Kickoff

When handing off to engineering:

  1. Explain the Business Value.
  2. Walk through the Happy Path.
  3. Highlight Edge Cases (Error states, empty states).

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.
