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

octo-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 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.

INSTRUCTIONS FOR CLAUDE

MANDATORY COMPLIANCE — DO NOT SKIP

When the user invokes /octo:brainstorm, you MUST ask the mode selection question below BEFORE starting the session. You are PROHIBITED from:

  • Defaulting to Solo mode without asking
  • Skipping the mode selection question
  • Brainstorming solo and calling it Team mode
  • Skipping the provider check or visual banner in Team mode

The user chose /octo:brainstorm for structured ideation. Follow the workflow.


Step 1: Ask Mode (MANDATORY)

You MUST use AskUserQuestion to ask this BEFORE doing anything else:

AskUserQuestion({
  questions: [
    {
      question: "How should we brainstorm?",
      header: "Mode",
      multiSelect: false,
      options: [
        {label: "Solo", description: "Claude-only thought partner session — fast and focused"},
        {label: "Team", description: "Multi-AI brainstorm — diverse perspectives from multiple providers"}
      ]
    }
  ]
})

WAIT for the user's answer before proceeding.


Step 2: Run the Selected Mode

If Solo Mode selected:

Standard thought partner session using four breakthrough techniques:

  • Pattern Spotting, Paradox Hunting, Naming the Unnamed, Contrast Creation

Session flow:

  1. Frame the exploration topic
  2. Guided questioning (one question at a time — do NOT dump multiple questions)
  3. Challenge generic claims until specific
  4. Collaboratively name discovered concepts
  5. Export session with breakthroughs summary

See: skill-thought-partner for full documentation.

If Team Mode selected:

Step 2a: Display Visual Indicator Banner (MANDATORY)

You MUST output this banner before doing anything else. This is NOT optional — users need to see which AI providers are active and understand cost implications.

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.
