brainstorm-loop

brainstorm-loop is a command for Claude Code from sjarmak/coding-agent-workflows. It costs 21 tokens per session (329 once invoked), scanned A, original, MIT.

A workflow for generating many different approaches to a feature, testing the leading ideas against possible failures, and choosing one.

In plain words
What is it for?
Use it when deciding how to build something, starting with brainstorming, then a pre-mortem—imagining why each idea failed—and finally a recorded choice.
Why use it?
It helps avoid settling on the first obvious solution and exposes risks before implementation begins.

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-loop 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 1mo 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

Workflow: Brainstorm Loop

For feature design and "how should we approach X" questions. Forces divergent volume under a uniqueness constraint, then filters by failure analysis.

Inputs

Input Source Description
problem caller The problem statement. Use the task title if dispatched.
context caller Constraints and prior art that define exclusion zones.

Steps

1. brainstorm

Run brainstorm: produce many candidate approaches under one hard constraint. No idea may take the same shape as any prior art or any earlier idea in this session. Volume plus shape-uniqueness is what gets past the obvious answer.

Exit: a set of shape-distinct candidates.

2. premortem (needs: brainstorm)

Run premortem on the top candidates: for each, assume it failed and list why. Drop candidates whose failure modes are fatal or unmitigable.

Exit: a shortlist of candidates that survive failure analysis.

3. converge (needs: premortem)

Run converge on the shortlist: pick one direction, state the trade-offs it accepts, and record the runners-up so the decision is auditable later. Where subagents are available, run it as a multi-agent debate; otherwise weigh the shortlist directly in one pass.

Exit: one chosen direction + rejected alternatives with reasons.

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.
