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.

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 | $0.00039 | $0.00676 |
| Opus 5.5 | $0.00016 | $0.00270 |
| Sonnet 5.5 | $0.00008 | $0.00135 |
| Haiku 4.5 | $0.00004 | $0.00068 |
Grade A, and why
brainstorming 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.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brainstorming
Turn vague ideas into concrete, well-formed plans through structured collaborative dialogue. This skill applies to any creative PM work: feature ideation, experiment design, strategy formation, or solution exploration.
When to Use
- "brainstorm ideas for..."
- "help me think through..."
- "I have an idea but it's not fully formed"
- "explore options for..."
- "what should we build for..."
- Before starting a PRD, experiment, or new initiative
Process
Phase 1: Understand the Problem
Ask one question at a time to understand:
- What's the context? — Product area, current state, what prompted this
- Who's the customer? — Reference
knowledge/_template/customer-segments.mdto ground in real personas - What's the problem? — Frame as: I am... I am trying to... But... Because... Which makes me feel...
- What does success look like? — Metric, outcome, or state change
- What are the constraints? — Timeline, resources, technical limitations, regulatory
Phase 2: Explore Approaches
- Generate 3 options ranging from conservative to ambitious
- For each option, assess:
- Customer impact — How much does this move the needle for the persona?
- Effort — Engineering, design, ops complexity
- Risk — What could go wrong? Reversible or irreversible?
- Strategic fit — Does it ladder to a strategic pillar? (Reference
knowledge/_template/strategy.md)
- Present a recommendation with reasoning
Phase 3: Sharpen the Idea
- Pressure-test the recommended approach:
- What's the hypothesis? ("We believe [action] will [outcome] for [segment] because [rationale]")
- What's the simplest version we could ship to learn?
- What would make us kill this idea?
- Define next steps: PRD, experiment, one-pager, or prototype
Output
A brainstorm summary:
- Problem (customer problem framework)
- Options explored (3, with trade-offs)
- Recommendation (with rationale)
- Hypothesis (testable)
- Next step (what to do now — and which skill to use: prd-writer, experiment-designer, one-pager)
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.

brainstorming is a skill published in the GitHub repository hardiktiwari/PM-operating-OS (5 stars, last pushed 5mo ago), licensed MIT. It adds 39 tokens to every session and 676 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 2026-08-31.
