brainstorm

A planning assistant for shaping a new software idea into a clear brief before development tasks are created.

In plain words
What is it for?
Use it when describing an app or other software you want to build, or when you need to plan a project before creating tasks.
Why use it?
It helps turn a vague idea into a defined project with a clearer scope. It is intended for new projects, not work already tracked in an existing repository.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add agents/frkak/piyaz/brainstorm
Clone the repo
git clone --depth 1 https://github.com/FrkAk/piyaz

Or install claude-code, the plugin that ships this one along with the rest of its 1 skill, 10 agents, 1 MCP server.

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 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 3d 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 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.
