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.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00024 | $0.11986 |
| Opus 5 | $0.00012 | $0.05993 |
| Sonnet 5 | $0.00005 | $0.02397 |
| Haiku 4.5 | $0.00002 | $0.01199 |
Grade A, and why
octo-extract 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 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.
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
When the user invokes this command (e.g., /octo:extract <target> or /octo:extract <target>):
Step 0: PDF Page Selection (if target is PDF)
CRITICAL: For PDF files > 10 pages, ask user which pages to extract:
// Check if target is a PDF file
if (target.endsWith('.pdf') && isFile(target)) {
// Use Claude Octopus PDF page selection utility
const pageCount = await getPdfPageCount(target);
if (pageCount > 10) {
console.log(`📄 Large PDF detected: ${pageCount} pages`);
console.log(`Reading all pages may use ${pageCount * 750} tokens (~${Math.ceil(pageCount/133)} API calls).`);
const selection = await AskUserQuestion({
questions: [{
question: `This PDF has ${pageCount} pages. Which pages would you like to extract?`,
header: "PDF Pages",
multiSelect: false,
options: [
{label: "First 10 pages", description: "Quick overview (pages 1-10)"},
{label: "Specific pages", description: "Enter custom page range"},
{label: "All pages", description: `Full document (~${Math.ceil(pageCount/133)} API calls)`}
]
}]
});
let pageParam = "";
if (selection === "First 10 pages") {
pageParam = "1-10";
} else if (selection === "Specific pages") {
pageParam = await askForInput("Enter page range (e.g., 1-5, 10, 15-20):");
}
// else "All pages" - use empty string
// Store for use in extraction phases
target = { path: target, pages: pageParam };
console.log(`✓ Will extract pages: ${pageParam || 'all'}`);
}
}
Example output:
📄 Large PDF detected: 45 pages
Reading all pages may use 33,750 tokens (~34 API calls).

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.

octo-extract is a command published in the GitHub repository nyldn/claude-octopus (4,061 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 11,986 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 2026-09-03.

Use this command when the user asks Stark to go all out, raise design quality broadly, use libraries well, make a UI feel actually designed, or coordinate research, typography, motion, usability, implementation, and QA in one pass.
motion-designer
Use when animation feels wrong. Transitions too slow or too bouncy, motion with no purpose, blanket transitions on every property, no reduced-motion support, or animation that drops frames.
