brainstorm

brainstorm is a skill for Claude Code, Codex from fakoli/fakoli-plugins. It costs 13 tokens per session (2,202 once invoked), scanned A, original, MIT.

A design-stage skill for turning an idea into a detailed software specification through conversation.

In plain words
What is it for?
Use it to explore a project, ask focused questions, compare approaches, and prepare a specification for the planning stage.
Why use it?
It helps clarify the goal, scope, constraints, and success criteria before implementation begins.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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 3d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/check-server.sh, scripts/helper.js, scripts/server.cjs, …), 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 — 237 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brainstorm — Design Phase

Turn ideas into fully-formed specs through structured dialogue: explore context, assess scope, ask one question at a time, propose approaches, present the design section by section, and hand off to /fakoli-flow:plan.


Process Flow

Start
  |
  v
[1. Explore project context]
  Read CLAUDE.md, project files, recent git log.
  Note any output path or naming conventions CLAUDE.md specifies.
  |
  v
[2. Assess scope]
  Does the request describe multiple independent subsystems?
  |
  YES --> Flag decomposition immediately. Do not ask detailed questions yet.
  |       Help the user decompose into sub-projects, then brainstorm the first one.
  |
  NO
  |
  v
[3. Ask clarifying questions]
  One question per message. Multiple choice preferred.
  Focus: purpose, constraints, success criteria.
  |
  v
[4. Auto-detect visual questions]
  Is this question about layout, mockups, diagrams, or visual comparison?
  |
  YES --> Offer visual companion (first time only, its own message).
  |       If accepted: start server, track PID, serve mockup.
  |       Subsequent visual questions in the same session reuse the server.
  |
  NO --> Stay in terminal even if companion is active.
  |
  v
[5. Propose 2-3 approaches]
  Lead with recommendation. Explain trade-offs.
  |
  v
[6. Present design section by section]
  Scale each section to its complexity.
  Ask "Does this section look right?" after each one.
  Revise before moving forward.
  |
  v
[7. Write spec]
  Save to docs/specs/<YYYY-MM-DD>-<topic>.md
  (or the path CLAUDE.md specifies — that path always wins).
  |
  v
[8. Self-review]
  Run the four checks inline. Fix issues before showing the user.
  |
  v
[9. User reviews spec]
  Ask the user to review the file. Wait for explicit approval.
  If changes requested: update the file, re-run self-review, re-ask.
  |
  v
[10. Hand off to /fakoli-flow:plan]

Files

What ships with it

7 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.

Changes

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.
