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 | $0.00076 | $0.01313 |
| Opus 5.5 | $0.00030 | $0.00525 |
| Sonnet 5.5 | $0.00015 | $0.00263 |
| Haiku 4.5 | $0.00008 | $0.00131 |
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 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.

Brainstorming
This skill provides detailed process knowledge for effective brainstorming sessions that clarify WHAT to build before diving into HOW to build it.
When to Use This Skill
Brainstorming is valuable when:
- Requirements are unclear or ambiguous
- Multiple approaches could solve the problem
- Trade-offs need to be explored with the user
- The user hasn't fully articulated what they want
- The feature scope needs refinement
Brainstorming can be skipped when:
- Requirements are explicit and detailed
- The user knows exactly what they want
- The task is a straightforward bug fix or well-defined change
Core Process
Phase 0: Assess Requirement Clarity
Before diving into questions, assess whether brainstorming is needed.
Signals that requirements are clear:
- User provided specific acceptance criteria
- User referenced existing patterns to follow
- User described exact behavior expected
- Scope is constrained and well-defined
Signals that brainstorming is needed:
- User used vague terms ("make it better", "add something like")
- Multiple reasonable interpretations exist
- Trade-offs haven't been discussed
- User seems unsure about the approach
If requirements are clear, suggest: "Your requirements seem clear. Consider proceeding directly to planning or implementation."
Phase 1: Understand the Idea
Ask questions one at a time to understand the user's intent. Avoid overwhelming with multiple questions.
Question Techniques:
-
Prefer multiple choice when natural options exist
- Good: "Should the notification be: (a) email only, (b) in-app only, or (c) both?"
- Avoid: "How should users be notified?"
-
Start broad, then narrow
- First: What is the core purpose?
- Then: Who are the users?
- Finally: What constraints exist?
-
Validate assumptions explicitly
- "I'm assuming users will be logged in. Is that correct?"
-
Ask about success criteria early
- "How will you know this feature is working well?"
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 davekilleen/Dex (508 stars, last pushed 2d ago), licensed MIT. It adds 76 tokens to every session and 1,313 once invoked, about $0.0003 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 2026-08-30.
