brainstorming

brainstorming is a skill for Claude Code, Codex from PedroMosquera/squadai. It costs 13 tokens per session (401 once invoked), scanned A, original, MIT.

A requirements and test-scenario planning guide for TDD, or test-driven development, where tests are planned before the code. It explores expected inputs, outputs, normal cases, edge cases, failures, and priorities.

In plain words
What is it for?
Use it at the start of a coding task to ask requirement questions and produce prioritised scenarios for normal use, invalid input, missing dependencies, partial failures, limits, and concurrency where relevant.
Why use it?
It helps expose unclear requirements and overlooked failure situations before implementation begins. This gives developers a clearer set of behaviours to test.

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 8d 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

Brainstorming Skill

Explore requirements and generate comprehensive test scenarios before any code is written. This skill is the first phase of the TDD pipeline.

Steps

  1. Understand the problem: Ask clarifying questions before generating scenarios.

    • What is the expected input and output?
    • What are the success criteria?
    • Are there performance or security constraints?
    • Who are the consumers of this functionality?
  2. Identify happy paths: List the primary usage flows.

    • Core feature usage with typical inputs
    • Most common call patterns
    • Expected return values and side effects
  3. Identify edge cases: Enumerate boundary and exceptional conditions.

    • Empty inputs, nil/null values, zero values
    • Maximum/minimum boundary values
    • Concurrent access scenarios (if applicable)
    • Large inputs or long-running operations
  4. Identify error scenarios: List all failure modes.

    • Invalid input (wrong type, out-of-range, malformed)
    • Missing dependencies (unavailable service, missing file)
    • Permission or authentication failures
    • Partial failures (some items succeed, some fail)
  5. Prioritize scenarios: Rank by risk and importance.

    • Critical: covers behavior that breaks the system if wrong
    • Important: covers common usage patterns
    • Nice-to-have: covers unusual but valid edge cases

Output Format

Produce a numbered list of test scenarios grouped by category:

Happy Paths

  1. [Scenario: input → expected output]

Edge Cases

  1. [Scenario: edge condition → expected behavior]

Error Scenarios

  1. [Scenario: error condition → expected error or fallback]

Do NOT write code. Only produce the scenario list. The Planner converts this into a test plan; the Implementer writes the code.

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.

brainstorming is a skill published in the GitHub repository PedroMosquera/squadai (8 stars, last pushed 1mo ago), licensed MIT. It adds 13 tokens to every session and 401 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 2026-08-31.
