brainstorming

brainstorming is a skill for Claude Code, Codex from itallstartedwithaidea/agent-skills. It costs 23 tokens per session (1,056 once invoked), scanned A, original, MIT.

A design-refinement skill that asks structured questions about requirements, constraints, edge cases, alternatives, and trade-offs before code is written.

In plain words
What is it for?
It is for clarifying vague feature requests and producing a shared design brief that guides later development.
Why use it?
It helps uncover missing requirements and difficult decisions before they become expensive changes during implementation.

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

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 2d 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.

Brainstorming

Part of Agent Skills™ by googleadsagent.ai™

Description

Brainstorming is a Socratic design refinement skill that activates before any code is written. It transforms vague requirements and rough ideas into well-defined implementation plans through structured questioning, constraint discovery, and alternative exploration. The agent refuses to write code until the problem space is sufficiently mapped.

This skill enforces a deliberate pause between "I want X" and "here's the code for X." By asking targeted questions about edge cases, scalability concerns, user experience implications, and architectural trade-offs, the agent surfaces hidden requirements that would otherwise become expensive mid-implementation discoveries. The process mirrors how senior engineers naturally probe requirements before committing to an approach.

The output is a crystallized design brief: a shared understanding between human and agent of what will be built, why specific approaches were chosen, and what was explicitly deferred. This artifact becomes the contract against which all subsequent implementation is measured.

Use When

  • A user presents a feature request without detailed specifications
  • The problem has multiple viable architectural approaches with meaningful trade-offs
  • Requirements contain ambiguous terms that could be interpreted differently
  • The scope of work is unclear or potentially unbounded
  • You detect assumptions that need validation before implementation begins
  • The task involves integrating with unfamiliar systems or APIs

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.

brainstorming is a skill published in the GitHub repository itallstartedwithaidea/agent-skills (36 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 1,056 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
