An agent skill by phuryn, from phuryn/pm-skills. Tags: brainstorming, design, market-analysis, product-strategy, strategy.
What it does
Brainstorm feature ideas for a new product in initial discovery from PM, Designer, and Engineer perspectives. Use when starting product discovery for a new product, exploring features for a startup idea, or doing initial ideation.
Install
With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:
npx skills add phuryn/pm-skills --skill brainstorm-ideas-newOr copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):
git clone --depth 1 https://github.com/phuryn/pm-skills
cp -r pm-skills/pm-product-discovery/skills/brainstorm-ideas-new ~/.claude/skills/brainstorm-ideas-newSafety box score
Grade A, minimal risk: 7 of 100 risk points, rated 2026-10-20. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.
This is a documentation-only ideation skill for early product discovery. It mainly produces written brainstorm output, with optional web lookup and a note to save a markdown document; it does not ship code, change settings, or access secrets. The main risks are mild network use for research and the possibility of writing a file in the current workspace.
| Category | Level | Why |
|---|---|---|
| Code & shell execution | 0 (none) | No scripts, shell commands, or code evaluation are included in `SKILL.md`. |
| Network access | 1 (low) | It says to "Use web search to understand the market if needed," which can send queries to external search/services, but this is optional and read-only. |
| Filesystem reach | 1 (low) | It instructs to "Save substantial output as a markdown document," implying writes in the working area only, with no external paths or deletions. |
| Secrets & credentials | 0 (none) | There is no request to collect, read, or transmit credentials, tokens, or private data. |
| Privilege & persistence | 0 (none) | No sudo, service registration, global install, or OS/shell configuration changes are requested. |
| Instruction hijack surface | 0 (none) | The skill contains normal task instructions only; no prompt-injection content, hidden text, or requests to ignore higher-level rules. |
| Irreversible actions | 0 (none) | It generates ideas and priorities only; it does not send messages, deploy, pay, book, or otherwise act on the user's behalf. |
| Transparency | 0 (none) | The file is plain markdown with readable instructions and no binaries, base64 blobs, or unpinned downloads. |
Before installing
- Decide whether you are comfortable with optional web searches for market research.
- Check that any generated markdown will be saved only in the workspace, not in a synced or sensitive folder.
- If you will provide market research files, review them for embedded secrets before passing them to the agent.
