What it does

Brainstorm Ideas Existing is an agent skill from phuryn/pm-skills. Brainstorm product ideas for an existing product using multi-perspective ideation from PM, Designer, and Engineer viewpoints. Use when generating new feature ideas, brainstorming solutions for an identified opportunity, or ideating with a product trio.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Brainstorming. The repository describes itself as: PM Skills Marketplace: 100+ agentic skills, commands, and plugins — from discovery to strategy, execution, launch, and growth. The licence is MIT.

When your agent uses it

  • Generating new feature ideas
  • Brainstorming solutions for an identified opportunity
  • Ideating with a product trio

Example prompts

  • “/brainstorm-ideas-existing”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Understand the opportunity: Confirm the product, objective, market segment, and desired outcomes. Ask for clarification if anything is…
  2. Ideate from three perspectives — generate 5 ideas each from
  3. Prioritize the top 5 ideas across all perspectives based on
  4. For each prioritized idea, provide

What it can do on your machine

Read from SKILL.md and the folder at commit 6058e29. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • productcompass.pm

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Brainstorm Ideas Existing loads about 736 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 300 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~736

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Brainstorm product ideas for an existing product using multi-perspective ideation from PM, Designer, and Engineer viewpoints. Use when generating new feature ideas, brainstorming solutions for an identified opportunity, or ideating with a product trio.

Brainstorm Product Ideas (Existing Product)

Multi-perspective ideation for continuous product discovery. Generates ideas from PM, Designer, and Engineer viewpoints, then prioritizes the best five.

Context

You are supporting a product trio performing continuous product discovery for $ARGUMENTS.

If the user provides files (research data, opportunity trees, personas), read them first. If they mention a product URL, use web search to understand the product.

Domain Context

Product Trio (Teresa Torres, Continuous Discovery Habits): PM + Designer + Engineer collaborate on discovery together. "Best ideas often come from engineers." Discovery is not linear — loop back if experiments fail. Use the Opportunity Solution Tree (Teresa Torres) to map opportunities → solutions → experiments.

Instructions

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

  1. Understand the opportunity: Confirm the product, objective, market segment, and desired outcomes. Ask for clarification if anything is ambiguous.

  2. Ideate from three perspectives — generate 5 ideas each from:

    • Product Manager: Focus on business value, strategic alignment, and customer impact
    • Product Designer: Focus on user experience, usability, and delight
    • Software Engineer: Focus on technical possibilities, data leverage, and scalable solutions
  3. Prioritize the top 5 ideas across all perspectives based on:

    • Strategic alignment with the stated objective
    • Potential impact on desired outcomes
    • Feasibility and effort required
    • Differentiation from existing solutions
  4. For each prioritized idea, provide:

    • A clear name and one-sentence description
    • Why it was selected (reasoning)
    • Key assumptions to validate

Think step by step. Present ideas in a clear, structured format.

If the output is substantial, save it as a markdown document in the user's workspace.
