About the project

Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.

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 C, and why

brainstorm scanned grade C with 2 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 7d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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. Do NOT default to Solo mode. Do NOT skip the question. The user must choose.


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.

MANDATORY: First, use the Bash tool to check provider availability:

set -euo pipefail

echo "PROVIDER_CHECK_START"
printf "codex:%s\n" "$(command -v codex >/dev/null 2>&1 && echo available || echo missing)"
printf "perplexity:%s\n" "$([ -n "${PERPLEXITY_API_KEY:-}" ] && echo available || echo missing)"
printf "opencode:%s\n" "$(command -v opencode >/dev/null 2>&1 && echo available || echo missing)"
printf "copilot:%s\n" "$(command -v copilot >/dev/null 2>&1 && echo available || echo missing)"
printf "qwen:%s\n" "$(command -v qwen >/dev/null 2>&1 && echo available || echo missing)"
printf "ollama:%s\n" "$(command -v ollama >/dev/null 2>&1 && curl -sf http://localhost:11434/api/tags >/dev/null 2>&1 && echo available || echo missing)"
printf "openrouter:%s\n" "$([ -n "${OPENROUTER_API_KEY:-}" ] && echo available || echo missing)"
printf "agy:%s\n" "$(command -v agy >/dev/null 2>&1 && echo available || echo missing)"
printf "grok:%s\n" "$(command -v grok >/dev/null 2>&1 && { [ -n "${XAI_API_KEY:-}" ] || [ -f "${HOME}/.grok/auth.json" ]; } && echo available || echo missing)"
echo "PROVIDER_CHECK_END"

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.
