What it does
Brainstorm is an agent skill from robertguss/claude-code-toolkit. Collaborative brainstorming partner for multi-session ideation projects. Use when the user wants to brainstorm, ideate, explore ideas, or think through problems—whether for SaaS products, software tools, book ideas, newsletter content, business strategies, or any creative/analytical challenge. Handles session continuity across days/weeks via versioned markdown documents. Includes brainstorming methods catalog and supports both connected (cross-project awareness) and clean-slate modes.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files and assets (for example `README.md`, `assets/templates/index-template.md` and `assets/templates/project-template.md`).
It sits in Agent Workflows, covering Brainstorming. The repository describes itself as: A collection of custom skills that extend Claude's capabilities with specialized workflows, methods, and domain knowledge.
When your agent uses it
- The user wants to brainstorm
- Think through problems—whether for SaaS products
- Newsletter content
- Business strategies
Example prompts
- “/brainstorm”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Session Start

- Session End
What it can do on your machine
Read from SKILL.md and the folder at commit f7fd35e. 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
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 1.7k tokens when it runs, and up to ~9.3k if it reads all its reference files. Until then it costs about 125 tokens; SKILL.md has 778 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 (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 778 words (~1,735 tokens).
“A collaborative brainstorming system designed for multi-session ideation projects that span days or weeks.”
