brainstorm

brainstorm is a skill for Claude Code, Codex from automagik-dev/genie. It costs 25 tokens per session (2,560 once invoked), scanned A, original, MIT.

An interactive skill for turning an unclear software idea into a concrete design. It records brainstorming notes in the project's .genie folder.

In plain words
What is it for?
Use it when an idea is early, ambiguous, or needs refinement. It helps explore requirements and produce a design ready for the next planning stage.
Why use it?
It gives shape to vague requirements before implementation begins, reducing confusion about scope and approach. It also checks existing project notes for related ideas.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

brainstorm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/design-review-evidence.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

brainstorm — Explore Before Planning

Runtime syntax: invoke the plugin copy through the active runtime's owner-qualified skill selector; use a bare selector only when intentionally selecting a user-tier copy (a separately installed personal copy; Genie no longer seeds this tier). Cross-skill prose below uses bare names as portable semantic routes; the orchestrator resolves the selector for the active runtime.

Collaborate on fuzzy ideas until they are concrete enough for wish.

When to Use

  • User has an idea but unclear scope or approach
  • Requirements are ambiguous and need interactive refinement
  • User explicitly invokes brainstorm

All artifacts live in .genie/ within the shared worktree. When spawned as a native subagent, the dispatcher curates seed context (file path + extracted section) into your prompt — use it directly; do not re-read what was already provided.

Flow

  1. Read context: scan relevant code, docs, conventions. Check the canonical .genie/INDEX.md for an existing entry matching this slug/topic — seed from it if found. If a legacy flat brainstorm jar (the pre-INDEX.md single-file index some repos still carry under .genie/) exists, migrate it first (see Index).
  2. Init persistence: create .genie/brainstorms/<slug>/DRAFT.md immediately; create .genie/INDEX.md if missing (see Index).
  3. Scope-size check: if the request spans multiple independent subsystems, decompose before refining (see Scope Size).
  4. Refine: fill WRS dimensions. Ask only what an unfilled dimension needs — when the request or context already settles a dimension, mark it filled and move on; never re-litigate decisions the user already made. Prefer concrete options over open questions.
  5. Show the WRS bar after every exchange; persist DRAFT.md whenever WRS changes.
  6. Pass the Simplicity Gate: establish the simplest complete approach before considering more machinery. Reject speculative complexity or defer it behind a measurable trigger (see Simplicity Gate).
  7. Propose approaches: 2-3 options with trade-offs, applying Design for Isolation. Recommend one and proceed when the choice follows from the request.
  8. Crystallize when WRS = 100 (see Crystallize).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

brainstorm is a skill published in the GitHub repository automagik-dev/genie (334 stars, last pushed 2d ago), licensed MIT. It adds 25 tokens to every session and 2,560 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
