What is bmad-brainstorming?

A guided brainstorming session for generating and developing ideas from a topic. It can act as a facilitator, a creative partner, or run the ideation for the user, depending on the chosen approach.

Use it when you want help brainstorming or exploring a problem, product, or topic. Choose whether you want to supply all the ideas, exchange ideas with the assistant, or receive a generated set of ideas.

It provides structured prompts and creative techniques when ordinary brainstorming produces only obvious ideas. It also makes the session style explicit so the user knows how much idea generation to expect from the assistant.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.02276
Opus 5	$0.00017	$0.01138
Sonnet 5	$0.00007	$0.00455
Haiku 4.5	$0.00003	$0.00228

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 11d 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.
{bmad-root} is the vendored vendor-skills/BMAD/ root.

On Activation

Resolve customization: uv run {bmad-root}/scripts/resolve_customization.py --skill {skill-root} --key workflow. On failure, use a subagent to read {skill-root}/customize.toml directly with defaults.
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).
Resolve {user_name}, {communication_language}, {document_output_language}, {output_folder}, {project_name} using sensible defaults (ask the user or omit {user_name}; English for language fields; infer {project_name} from the Hedgehog project); {date} is today. Missing values → neutral defaults; never block.
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; never load it otherwise. Outside headless, you generate ideas yourself only in autonomous mode (references/mode-autonomous.md) — never in facilitator or partner mode.
Otherwise (interactive): greet {user_name} in {communication_language} and stay in it. Note that bmad-advanced-elicitation is available any time (mention only if installed). 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).

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.
