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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00028 | $0.10160 |
| Opus 5.5 | $0.00011 | $0.04064 |
| Sonnet 5.5 | $0.00006 | $0.02032 |
| Haiku 4.5 | $0.00003 | $0.01016 |
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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 1,067 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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_planfor 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.

brainstorm-with-file is a skill published in the GitHub repository catlog22/Claude-Code-Workflow (2,124 stars, last pushed 4mo ago), licensed MIT. It adds 28 tokens to every session and 10,160 once invoked, about $0.0001 per session on Opus 5.5. 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.
