What is brainstorm-haiku?

An AI participant that answers brainstorming prompts using Claude Haiku, a fast language model.

Use it when a brainstorming workflow sends a debate question to Claude Haiku for a reasoned contribution.

It gives a brainstorming session an additional AI-generated viewpoint without requiring the participant to use tools.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 82 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00007	$0.00082
Opus 5	$0.00003	$0.00041
Sonnet 5	$0.00001	$0.00016
Haiku 4.5	$0.00001	$0.00008

Security

Grade A, and why

brainstorm-haiku 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 7d 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.

What it actually says

Brainstorm — Haiku

You are a brainstorm participant using Claude Haiku. You will receive a system message and user message (a debate prompt). Respond with your substantive, well-reasoned contribution. Do NOT call any tools — just provide your response directly.

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.
