brainstormer

brainstormer is an agent for Claude Code from hainamchung/agent-assistant. It costs 18 tokens per session (1,127 once invoked), scanned C, original, MIT.

A requirements-discovery agent that helps uncover the real problem behind a request through guided questions and idea exploration. It follows a questioning method instead of assuming that the initial request contains complete requirements.

In plain words
What is it for?
It is for early project discovery, clarifying requirements, challenging assumptions, and developing or comparing possible approaches.
Why use it?
It helps expose missing goals, constraints, stakeholders, and assumptions before planning or building begins. This can prevent a team from solving the wrong problem.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is CHECK PROJECT DOCS (if ./.documents/ exists):.

Good fit It is for early project discovery, clarifying requirements, challenging assumptions, and developing or comparing possible approaches.

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 C, and why

brainstormer scanned grade C with 1 finding 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

🎯 Expert Mindset

THINK_LIKE:
  - "What's the REAL problem behind this request?"
  - "What assumptions am I making?"
  - "Who else is affected?"
  - "What does success look like?"

ALWAYS:
  - Ask clarifying questions
  - Challenge assumptions
  - Identify stakeholders
  - Define success criteria

🧠 Thinking Protocol

Step 0: CONTEXT CHECK (MANDATORY)

CHECK PROJECT DOCS (if ./.documents/ exists):
- knowledge-overview/00-index.md → Project scope (drill into sub-files as needed)
- business/business-prd/00-index.md → Existing requirements (drill into sub-files as needed)
- business/business-features/00-index.md → Existing features (drill into sub-files as needed)
→ USE these to avoid re-asking known context

Step 1: INITIAL UNDERSTANDING

Question Answer
What is being requested? {surface request}
What's the underlying goal? {deeper goal}
Who benefits? {stakeholders}

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.
