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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.01197 |
| Opus 5.5 | $0.00022 | $0.00479 |
| Sonnet 5.5 | $0.00011 | $0.00239 |
| Haiku 4.5 | $0.00005 | $0.00120 |
Grade A, and why
growth-loops 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 1mo 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.

Growth Loops
Overview
Identify and design growth loops (flywheels) that create sustainable traction. This skill evaluates five proven growth loop mechanisms to reduce reliance on paid acquisition and build product-led growth.
When to Use
- Designing growth mechanisms for a product
- Building sustainable viral or referral traction
- Reducing reliance on paid acquisition
- Analyzing competitor growth strategies
- Optimizing product for product-led growth
The 5 Growth Loop Types
1. Viral Loop
Product content created by users gets shared on external platforms, bringing new users back to the product.
- Mechanism: Users create content in-product → Share on social/external platforms → New users discover and signup
- Example: Figma designs shared as links, Loom videos shared in emails
- Strength: Exponential user acquisition if content is inherently shareable
- Challenge: Requires highly shareable output and strong incentive to share
2. Usage Loop
Users create content or value within the product, then share it, which invites new users or drives re-engagement.
- Mechanism: User creates → Shares creation → Others consume → Become engaged users
- Example: Twitter threads, Medium articles, Notion templates shared publicly
- Strength: Growth tied directly to product usage and network effects
- Challenge: Requires content creation friction to be very low
3. Collaboration Loop
Users invite colleagues to co-create or collaborate within the product, expanding the user base within organizations.
- Mechanism: User creates → Invites colleagues for collaboration → Colleagues discover product value
- Example: Google Docs invitations, Figma team projects, Slack channels
- Strength: Deep organizational penetration and high retention
- Challenge: Works best for collaborative/team-based products
4. User-Generated Loop
Users discover new content or features through other users' creations, then create and share their own content.
- Mechanism: User discovers content → Creates similar content → Shares creation → Others discover
- Example: TikTok, Pinterest, YouTube trends driving creator participation
- Strength: Creates content flywheel and network effects
- Challenge: Requires critical mass of quality content to sustain
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.

growth-loops is a skill published in the GitHub repository phuryn/pm-skills (27,375 stars, last pushed 9d ago), licensed MIT. It adds 54 tokens to every session and 1,197 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
