What is brainstorm-ideas-new?

A new-product brainstorming session generates feature ideas for a product that is still in its initial discovery stage. It considers the product manager's, designer's, and engineer's viewpoints.

Use it when exploring a startup idea, defining possible features, or testing whether a new product should exist. It can use supplied market research or competitor information and produces ideas from all three roles.

It gives an early product idea several practical perspectives before the team commits to building it. This helps explore value, user experience, feasibility, and possible market fit together.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.00492
Opus 5.5	$0.00020	$0.00197
Sonnet 5.5	$0.00010	$0.00098
Haiku 4.5	$0.00005	$0.00049

Security

Grade A, and why

brainstorm-ideas-new 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 2mo 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.

Brainstorm Product Ideas (New Product)

Multi-perspective ideation for initial product discovery of a new product. Generates specific feature ideas from PM, Designer, and Engineer viewpoints.

Context

You are supporting initial product discovery for a new product: $ARGUMENTS.

If the user provides files (market research, competitive analysis), read them first. Use web search to understand the market if needed.

Domain Context

Initial Discovery vs Continuous Discovery: Initial Discovery focuses on vision, business model, and market validation — you're testing whether the product should exist. Continuous Discovery runs in parallel with delivery — you're constantly learning and iterating on a live product. This skill is for initial discovery.

Instructions

The user will describe their target segment, opportunity, and desired outcomes. Work through these steps:

Understand the opportunity: Confirm the product concept, target market segment, and what the users want to achieve.
Ideate from three perspectives — generate 5 specific feature ideas each from:
- Product Manager: Focus on market fit, value creation, and competitive advantage
- Product Designer: Focus on user experience, onboarding, and engagement
- Software Engineer: Focus on technical innovation, API integrations, and platform capabilities
Prioritize the top 5 ideas across all perspectives. For a new product, weight heavily toward:
- Core value delivery (does it solve the primary problem?)
- Speed to validate (can we test this quickly?)
- Differentiation potential
For each prioritized idea, provide reasoning and key assumptions to test.

Think step by step. Save substantial output as a markdown document.

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.
