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
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 | $0.00018 | $0.03014 |
| Opus 5 | $0.00009 | $0.01507 |
| Sonnet 5 | $0.00004 | $0.00603 |
| Haiku 4.5 | $0.00002 | $0.00301 |
Grade B, and why
octo-review scanned grade B 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 4d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts
The opening of the file, as written. The whole thing — 256 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/octo:review
Load skills/blocks/engineering-method-selection.md from the installed plugin
and apply only the methods relevant to this task. Preserve this entry point's
execution contract and output format. Read referenced skills as instructions;
do not invoke the current command recursively or add provider calls from a seat.
MANDATORY COMPLIANCE — DO NOT SKIP
When the user explicitly invokes /octo:review, you MUST execute the enhanced multi-provider review workflow below. You are PROHIBITED from substituting Claude-native /review, direct reading, or a single-model review unless the user changes commands.
Positioning
Three review entry points coexist in Claude Code v2.1.111+ — pick the right one per context:
| Command | Scope | Providers | When |
|---|---|---|---|
Claude-native /review |
Single-turn, current diff | Claude only | Ordinary review, one perspective suffices |
/ultrareview (CC v2.1.111+) |
Cloud, parallel multi-agent | Claude parallelism | Pre-merge PR review without leaving CC |
/octo:review (this) |
Multi-LLM, inline PR comments | Claude + available providers | Provider diversity, adversarial cross-check, stricter escalation |
Use /octo:review when the user explicitly wants enhanced multi-LLM review, multiple model opinions, provider diversity, or stricter escalation workflows. If CC v2.1.111+ and the user just says "review this", prefer /ultrareview unless provider diversity is specifically requested.
When the user invokes this command (e.g., /octo:review <arguments>):
MANDATORY: Before displaying the banner or starting the review, use the Bash tool to check provider availability:
echo "PROVIDER_CHECK_START"
printf "codex:%s\n" "$(command -v codex >/dev/null 2>&1 && echo available || echo missing)"
printf "agy:%s\n" "$(command -v agy >/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)"
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.

octo-review is a command published in the GitHub repository nyldn/claude-octopus (4,061 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 3,014 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
