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

writer-brainstorm 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 28d 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.

What it actually says

Story brainstorming

When to use

Use when a story has an unresolved creative question or the author wants alternatives before committing.

Inputs and assumptions

Ask for the specific uncertainty, existing constraints, desired reader effect, and what must remain unchanged. Do not restart the entire premise to solve a small scene problem.

Portable workflow

  1. Read relevant project decisions using the project workflow.
  2. Frame the actual choice, such as whether a betrayal should change trust, status, or knowledge.
  3. Offer a small set of distinct options with different causal mechanisms, not renamed versions of one idea.
  4. For each option, explain what the reader gains, what must be set up, and what later consequences it creates.
  5. Include a less obvious option when it serves the brief. Ask the author which direction to develop.
  6. Preserve useful rejected options as proposals only when saving is requested.

Safety and side effects

Default to discussion. Do not overwrite approved plans or convert exploratory suggestions into established events.

Scripts, references, and dependencies

No external dependencies. Use the shared project workflow for approval and saved-state handling.

Verification

Options should differ in stakes or consequences. Check each against the author's constraints and identify the decision still awaiting approval.

Pi adapter

Use /writer brainstorm --brief "Find three motives for the mentor's disappearance" in an existing project.

Changes

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.
