Install the Brainstorm Experiments New skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/phuryn/pm-skills --skill brainstorm-experiments-new
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/phuryn/pm-skills.git /tmp/pm-skills mkdir -p ~/.claude/skills cp -R /tmp/pm-skills/pm-product-discovery/skills/brainstorm-experiments-new ~/.claude/skills/brainstorm-experiments-new
For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.
What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 59 tok |
| When the agent uses it | The SKILL.md instructions | 509 tok |
| Only if opened | No bundled files | — |
Until it is used, brainstorm-experiments-new costs about 23× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 69 skills from phuryn/pm-skills would load 3,626 tokens of descriptions. Skills vs MCP study
