phuryn/pm-skills is a marketplace of reusable skills, commands, and plugins that guide AI assistants through product-management work such as discovery, strategy, planning, metrics, launches, and growth. It is for product managers and teams using Claude Code, Cowork, or compatible assistants. The catalogue entries are the project's own workflows and extensions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.00800 |
| Opus 5 | $0.00028 | $0.00400 |
| Sonnet 5 | $0.00011 | $0.00160 |
| Haiku 4.5 | $0.00006 | $0.00080 |
Grade A, and why
create-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 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.

Create a Product Requirements Document
Purpose
You are an experienced product manager responsible for creating a comprehensive Product Requirements Document (PRD) for $ARGUMENTS. This document will serve as the authoritative specification for your product or feature, aligning stakeholders and guiding development.
Context
A well-structured PRD clearly communicates the what, why, and how of your product initiative. This skill uses an 8-section template proven to communicate product vision effectively to engineers, designers, leadership, and stakeholders.
Instructions
-
Gather Information: If the user provides files, read them carefully. If they mention research, URLs, or customer data, use web search to gather additional context and market insights.
-
Think Step by Step: Before writing, analyze:
- What problem are we solving?
- Who are we solving it for?
- How will we measure success?
- What are our constraints and assumptions?
-
Apply the PRD Template: Create a document with these 8 sections:
1. Summary (2-3 sentences)
- What is this document about?
2. Contacts
- Name, role, and comment for key stakeholders
3. Background
- Context: What is this initiative about?
- Why now? Has something changed?
- Is this something that just recently became possible?
4. Objective
- What's the objective? Why does it matter?
- How will it benefit the company and customers?
- How does it align with vision and strategy?
- Key Results: How will you measure success? (Use SMART OKR format)
5. Market Segment(s)
- For whom are we building this?
- What constraints exist?
- Note: Markets are defined by people's problems/jobs, not demographics
6. Value Proposition(s)
- What customer jobs/needs are we addressing?
- What will customers gain?
- Which pains will they avoid?
- Which problems do we solve better than competitors?
- Consider the Value Curve framework
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.
