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-with-file 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 today.

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.

Codex Brainstorm-With-File Prompt

Overview

Interactive brainstorming workflow with documented thought evolution. Expands initial ideas through questioning, inline multi-perspective analysis, external research, and iterative refinement.

Core workflow: Seed Idea → Expand → Multi-Perspective Explore → Research → Refine → Crystallize → Next Step

Key features:

  • brainstorm.md: Complete thought evolution timeline
  • Multi-perspective analysis: Creative + Pragmatic + Systematic (serial, inline)
  • External research: Web search for inspiration, patterns, and best practices via web.run
  • Idea expansion: Progressive questioning and exploration
  • Diverge-Converge cycles: Generate options then focus on best paths
  • Progress tracking: functions.update_plan for real-time phase progress visibility
  • Structured handoff: Terminal gate with execution planning, issue creation, or completion

Auto Mode

When --yes or -y: Auto-confirm exploration decisions, use recommended perspectives, skip interactive scoping.

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.
