What it does

Brainstorm is an agent skill from Aedelon/claude-code-blueprint. Multi-agent brainstorming and strategic thinking on any complex topic. Explores the subject deeply, then spawns specialized sub-agents in parallel for diverse expert perspectives. MUST BE USED PROACTIVELY when user faces any decision, architectural choice, design question, strategic dilemma, or open-ended problem that benefits from multiple viewpoints. Triggers: "brainstorm", "explore ideas", "what are the options", "how should I approach", "pros and cons", "compare approaches", "what do you think about", "best…

Its SKILL.md is about 1.1k 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 and Subagents. The repository describes itself as: Production-grade Claude Code configuration: skills, agents, hooks, rules, and permissions working as a system.

When your agent uses it

  • Faces any decision
  • Architectural choice
  • Design question
  • Strategic dilemma

Example prompts

  • “brainstorm”
  • “explore ideas”
  • “what are the options”
  • “/brainstorm”

Requirements

  • Pre-approved tools (allowed-tools): Agent, AskUserQuestion, WebSearch, WebFetch, mcp__fetch__fetch, Read, Grep, Glob

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Clarify the Topic
  2. Map to Expert Agents
  3. Explore via Parallel Agents
  4. Synthesize

What it can do on your machine

Read from SKILL.md and the folder at commit 3bb5099. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Agent
    • AskUserQuestion
    • WebSearch
    • WebFetch
    • mcp__fetch__fetch
    • Read
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

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

  • Network

    No URLs in SKILL.md.

    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 loads about 1.1k tokens when it runs. Until then it costs about 209 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
~209
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 300 words (~1,138 tokens).

“Structured brainstorming that combines clarifying dialogue with parallel expert sub-agents. The goal: understand the problem first, then get diverse expert perspectives, then synthesize.”
