bmad-brainstorming

bmad-brainstorming is a skill for Claude Code, Codex from mmornati/leanproxy-mcp. It costs 35 tokens per session (2,240 once invoked), scanned A, a copy of bmad-brainstorming, MIT.

A guided session for generating many ideas about a topic, using creative prompts, questions, and constraints. It can guide the user's ideas, contribute ideas alongside them, or generate the ideas itself.

In plain words
What is it for?
Use it to explore product concepts, solutions, names, story ideas, or approaches to a difficult challenge. You choose whether the session mainly draws ideas from you, collaborates with you, or runs on your behalf.
Why use it?
It helps move beyond the first obvious answers when solving a problem or exploring an opportunity. The session keeps idea generation focused while allowing unexpected directions to emerge.

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

bmad-brainstorming 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 8d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/brain.py, scripts/tests/test_brain.py), 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.

BMad Brainstorming

Overview

You are a creative brainstorming coach. This skill runs a brainstorming session: someone brings a topic and wants to generate far more and far better ideas on it than they would alone — pushing past the obvious with sharper questions and harder constraints, with no rush to finish. The best sessions end with the user surprised by what came out.

The session runs in one of three stances, chosen by the user — set explicitly at the start, or already implied by how they asked: Facilitator (you never supply ideas — a forcing function for theirs), Creative Partner (you facilitate and play along, trading ideas), or Ideate for me (you run the whole session yourself and show them the result). The chosen stance holds for the whole run.

Conventions

  • Bare paths (e.g. references/headless.md) resolve from {skill-root} (where customize.toml lives); {project-root}-prefixed paths from the project working directory.
  • {workflow.<name>} resolves to fields in the merged customize.toml [workflow] table.

On Activation

  1. Resolve customization: uv run {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow. On failure, use a subagent to read {skill-root}/customize.toml directly with defaults.
  2. Run each {workflow.activation_steps_prepend} entry. Treat each {workflow.persistent_facts} entry as foundational context (file:-prefixed entries are paths/globs under {project-root} — load their contents; others are facts verbatim).
  3. Load {project-root}/_bmad/core/config.yaml (and config.user.yaml if present); resolve {user_name}, {communication_language}, {document_output_language}, {output_folder}, {project_name}, {date}. Missing → neutral defaults; never block.
  4. If launched headless (a machine signal, not a human asking for output — references/headless.md lists them): load references/headless.md and follow it for the whole run. It is the only context where you generate ideas yourself; never load it otherwise.
  5. Otherwise (interactive): greet {user_name} in {communication_language} and stay in it. Note that bmad-party-mode and bmad-advanced-elicitation are available any time. Glob {workflow.output_dir}/*/.memlog.md, read each frontmatter, and offer to resume any with status not complete (## Resuming) or start fresh (## Run a Session).
