brainstorm

brainstorm is a skill for Codex from automagik-dev/genie. It costs 26 tokens per session (1,861 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 25d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (references/design-review-evidence.mjs, references/round-ledger.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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brainstorm

Use when the problem, approach, or boundaries need decisions. Explore with the user; do not implement. Resume a related draft rather than starting another: the slug names .genie/brainstorms/<slug>/, whose DRAFT.md carries the state of every round.

The brainstorm is a saved workflow that runs one round per invocation, because a workflow cannot wait for a person: the owner answers between runs. The single source of truth is .claude/workflows/brainstorm.js in the genie repository's workflow catalog (see .claude/workflows/README.md there); this skill is its front door and carries no stage roster of its own. On a runtime that runs saved workflows, run the script at <repository root>/.claude/workflows/brainstorm.js when that file exists, otherwise ~/.claude/workflows/brainstorm.js (delivered by genie install / genie update); give the runtime that explicit script path, never a bare name — both scopes carry these names and the order a name resolves in is undocumented. On a runtime that does not, or where neither file exists, follow "Without a workflow surface" below.

Invoke

Pass {slug, request?, answers?, repo, tools: {ledger, evidence, reviewContract}, councilCeiling, repairBudget, model?, timestamp} through args, every path absolute:

  • slug is lowercase letters, digits and dashes; request is the idea in the owner's words; repo is the repository root; timestamp is the caller's clock, since the workflow has none; model pins every stage.
  • tools resolve from this skill's own directory, never from the checkout, so a round runs from any repository: ledger is references/round-ledger.mjs, evidence is references/design-review-evidence.mjs, and reviewContract is review/SKILL.md in the skills directory that holds this one, the review skill installed beside it; a single-skill install has none, and the run ends failed naming the path. The design template stays at references/design-template.md beside the ledger, where the workflow finds it.
  • councilCeiling is the value genie config get budgets.maxCouncilsPerBrainstorm prints and repairBudget the value genie config get budgets.maxEscalationsPerGroup prints, each passed as an integer, never as the printed string: the workflow treats anything that is not an integer as unset, so the string "0" would quietly raise an owner's ceiling of 0 to the default 1. When genie is absent or a read exits non-zero — an installed release older than the council key exits 1 on it — pass that value's schema default (ceiling 1, repair budget 2) and say so when you relay the result.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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 (345 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 1,861 once invoked, about $0.0001 per session on Opus 5.5. 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.
