What it does
Brainstorm is an agent skill from serpro69/claude-toolbox. TRIGGER when: asked to brainstorm, think through, explore, or pressure-test a technical idea or decision through conversation. Interviews adaptively, asks one question at a time, and closes with a chat recap. For technical products, architecture, infrastructure, tools, operations, and engineering workflows. Written design/specification and task-list requests belong to $kk:design; durable domain glossary/reference kits to $kk:model; implementation and fixes to $kk:implement. Not for nontechnical brainstorming.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 64 other files (for example `evals/README.md`, `evals/architecture-audience/eval.json` and `evals/architecture-audience/oracle/runbook.md`).
It sits in Agent Workflows, covering Brainstorming. The repository describes itself as: Minimal by design, explicitly multi-lang, production-ready and battle-tested collection of configs and plugins for your Claude Code agentic development workflows: mcp, configs…
When your agent uses it
- : asked to brainstorm
- Pressure-test a technical idea
- Decision through conversation
Example prompts
- “/brainstorm”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Load reasoning references. Read shared-ideation-frameworks.md and shared-idea-refinement-criteria.md. They supply lenses, not a mandatory…
- Establish the current decision. Use the idea and context already supplied. Ask a framing question only to resolve a real ambiguity about…
- Interview and investigate. Keep settled decisions, assumptions, open questions, and their dependencies in conversational context.
- Converge and close in chat. Stop when the idea, rationale, meaningful trade-offs, material uncertainties, and next decision are clear…
What it can do on your machine
Read from SKILL.md and the folder at commit c2d28c9. 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):
github.com
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 1.3k tokens when it runs. Until then it costs about 131 tokens; SKILL.md has 581 words of instructions outside code blocks.
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 581 words (~1,261 tokens).
“Help the user reach their next decision: pursue, discard, narrow, or investigate an idea. Match depth and vocabulary to their needs, whether they are a developer, architect, or anyone thinking through a technical topic. An implementation-ready specification is not required.”
