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 | $0.00067 | $0.00795 |
| Opus 5 | $0.00034 | $0.00398 |
| Sonnet 5 | $0.00013 | $0.00159 |
| Haiku 4.5 | $0.00007 | $0.00080 |
Grade A, and why
think-brainwriting 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 11d 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.

Brainwriting
Verbal group brainstorming reliably underperforms: only one person talks at a time (production blocking), and the room anchors on the first speaker. Brainwriting removes those losses by generating ideas silently and in parallel, then building on each other's written ideas. This skill adapts that for solo-plus-AI: produce several genuinely independent idea streams (distinct angles, generated without contaminating each other), then run a build-on round and consolidate into a shortlist. The output is an idea pool. The key is keeping the streams independent first; collapsing into one stream throws away the mechanism that does the work.
When to Use
- You need breadth of options and want to avoid premature convergence.
- Anchoring or conformity would otherwise narrow the ideas (a single brainstorm).
- Early divergent generation, before any selection.
When NOT to Use
- When you need to converge, rank, or decide (use a decision skill).
- When deep single-expert reasoning beats breadth.
- If the result would be volume with no build-on and no selection.
Instructions
When asked to brainwrite, follow these steps:
- State the prompt for ideation in one line.
- Generate independent streams. Produce 3 to 4 separate idea streams, each from a distinct angle, persona, or constraint, generated as if blind to the others. Keep them visibly separate. Aim for a quota per stream.
- Build on, across streams. Now combine and extend: take ideas from one stream and push them with another's logic. This is where brainwriting beats parallel lists.
- Consolidate and de-duplicate. Merge near-duplicates; keep the distinct ideas.
- Shortlist. Select the strongest ideas to carry forward, noting why.
- Emit the idea pool per
references/TEMPLATE.md.
Output Format
Use the template in references/TEMPLATE.md. The deliverable is the separate streams, the build-on round, and a consolidated shortlist, not prose.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

think-brainwriting is a skill published in the GitHub repository product-on-purpose/thinking-framework-skills (15 stars, last pushed today), licensed Apache-2.0. It adds 67 tokens to every session and 795 once invoked, about $0.0003 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.
