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 | $0.00021 | $0.00618 |
| Opus 5 | $0.00010 | $0.00309 |
| Sonnet 5 | $0.00004 | $0.00124 |
| Haiku 4.5 | $0.00002 | $0.00062 |
Grade A, and why
Brainstorming Ideas Into Designs 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 yesterday.
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 Ideas Into Designs
Overview
Transform rough ideas into fully-formed designs through structured questioning and alternative exploration.
Core principle: Ask questions to understand, explore alternatives, present design incrementally for validation.
Announce at start: "I'm using the Brainstorming skill to refine your idea into a design."
The Process
Phase 1: Understanding
- Check current project state in working directory
- Ask ONE question at a time to refine the idea
- Prefer multiple choice when possible
- Gather: Purpose, constraints, success criteria
Phase 2: Exploration
- Propose 2-3 different approaches
- For each: Core architecture, trade-offs, complexity assessment
- Ask your human partner which approach resonates
Phase 3: Design Presentation
- Present in 200-300 word sections
- Cover: Architecture, components, data flow, error handling, testing
- Ask after each section: "Does this look right so far?"
Phase 4: Worktree Setup (for implementation)
When design is approved and implementation will follow:
- Announce: "I'm using the Using Git Worktrees skill to set up an isolated workspace."
- Switch to skills/collaboration/using-git-worktrees
- Follow that skill's process for directory selection, safety verification, and setup
- Return here when worktree ready
Phase 5: Planning Handoff
Ask: "Ready to create the implementation plan?"
When your human partner confirms (any affirmative response):
- Announce: "I'm using the Writing Plans skill to create the implementation plan."
- Switch to skills/collaboration/writing-plans skill
- Create detailed plan in the worktree
When to Revisit Earlier Phases
You can and should go backward when:
- Partner reveals new constraint during Phase 2 or 3 → Return to Phase 1 to understand it
- Validation shows fundamental gap in requirements → Return to Phase 1
- Partner questions approach during Phase 3 → Return to Phase 2 to explore alternatives
- Something doesn't make sense → Go back and clarify
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 Ideas Into Designs is a skill published in the GitHub repository obra/superpowers-skills (744 stars, last pushed 10mo ago), licensed MIT. It adds 21 tokens to every session and 618 once invoked, about $0.0001 per session on Opus 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.
