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 | $0.00012 | $0.00311 |
| Opus 5 | $0.00006 | $0.00156 |
| Sonnet 5 | $0.00002 | $0.00062 |
| Haiku 4.5 | $0.00001 | $0.00031 |
Grade A, and why
costs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
91% identical to octo-costs — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Cost Dashboard (/octo:costs)
For table output, your first output line MUST be 🐙 Octopus Cost Dashboard.
For JSON, emit only the helper output—no banner or commentary.
This v10 compatibility command shows the cost-focused view of /octo:usage.
It is scheduled for removal in v11.
EXECUTION CONTRACT (Mandatory)
When the user invokes /octo:costs, run the helper once with the Bash tool:
OCTO_ROOT="${CLAUDE_PLUGIN_ROOT:-${HOME}/.claude-octopus/plugin}"
helper="$OCTO_ROOT/scripts/helpers/usage-report.sh"
if [[ ! -x "$helper" ]]; then
echo "ERROR: Claude Octopus usage report helper is unavailable. Run /octo:setup." >&2
exit 1
fi
format="table"
case " $ARGUMENTS " in
*" --format json "*|*" --format=json "*) format="json" ;;
esac
"$helper" --view costs --format "$format"
Choose the format before invoking the helper and invoke it exactly once. For JSON, emit only the helper output. The helper owns pricing, session aggregation, provider rows, and the workflow cost breakdown. Do not inspect usage files or calculate rates inside the model response.
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.

costs is a command published in the GitHub repository nyldn/claude-octopus (4,061 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 311 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to octo-costs, differing in 3 lines, and is treated as a copy.
