brainstorm

brainstorm is a command for Claude Code from lxyer/multi-agent-collaboration-system. It costs 0 tokens per session (2,814 once invoked), scanned A, a copy of brainstorm, MIT.

A guided conversation for discovering and narrowing software requirements before implementation. It records the task, researches technical choices when needed, and asks one question at a time.

In plain words
What is it for?
It is for defining an initial version, comparing implementation options, and clarifying decisions about user experience, reliability, maintenance, cost, performance, and testing.
Why use it?
It helps when a development request is unclear or has several reasonable solutions with different trade-offs.

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.

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.

Brainstorm - Requirements Discovery (AI Coding Enhanced)

Guide AI through collaborative requirements discovery before implementation, optimized for AI coding workflows:

  • Task-first (capture ideas immediately)
  • Action-before-asking (reduce low-value questions)
  • Research-first for technical choices (avoid asking users to invent options)
  • Diverge → Converge (expand thinking, then lock MVP)

When to Use

Triggered from /trellis:start when the user describes a development task, especially when:

  • requirements are unclear or evolving
  • there are multiple valid implementation paths
  • trade-offs matter (UX, reliability, maintainability, cost, performance)
  • the user might not know the best options up front

Core Principles (Non-negotiable)

  1. Task-first (capture early) Always ensure a task exists at the start so the user's ideas are recorded immediately.

  2. Action before asking If you can derive the answer from repo code, docs, configs, conventions, or quick research — do that first.

  3. One question per message Never overwhelm the user with a list of questions. Ask one, update PRD, repeat.

  4. Prefer concrete options For preference/decision questions, present 2–3 feasible, specific approaches with trade-offs.

  5. Research-first for technical choices If the decision depends on industry conventions / similar tools / established patterns, do research first, then propose options.

  6. Diverge → Converge After initial understanding, proactively consider future evolution, related scenarios, and failure/edge cases — then converge to an MVP with explicit out-of-scope.

  7. No meta questions Do not ask "should I search?" or "can you paste the code so I can continue?" If you need information: search/inspect. If blocked: ask the minimal blocking question.


Step 0: Ensure Task Exists (ALWAYS)

Before any Q&A, ensure a task exists. If none exists, create one immediately.

  • Use a temporary working title derived from the user's message.
  • It's OK if the title is imperfect — refine later in PRD.

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 command published in the GitHub repository lxyer/multi-agent-collaboration-system (1 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,814 tokens. A static security scan graded it A with 0 findings. It is 100% identical to brainstorm, differing in 0 lines, and is treated as a copy.
