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 | $0.00010 | $0.00367 |
| Opus 5 | $0.00005 | $0.00183 |
| Sonnet 5 | $0.00002 | $0.00073 |
| Haiku 4.5 | $0.00001 | $0.00037 |
Grade A, and why
launch-rhino 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
100% identical to launch-rhino — 0 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
Spawn one Rhino managed by the router. The router (rhino-mcp-router.exe, shipped inside the Rhino-MCP-Platform yak) is the single stdio MCP server Claude Code talks to. It owns process lifecycle and port allocation — no port probing, no /mcp reconnect, no bash needed.
Argument
$1— optional Rhino version (8,WIP,9). Defaults to whatever the router was configured with at startup (typically8).
If $1 doesn't match one of the supported versions, ask the user to clarify rather than guess.
Step 1 — spawn
Call:
mcp__plugin_rhino-mcp_rhino__spawn_slot(version="$1")
(Omit version to use the router's default.)
The call returns a ChildRhino object: { slot_id, port, pid, version }. The slot_id is an animal name (armadillo, axolotl, …).
Step 2 — report
Tell the user the slot ID and let them know subsequent tool calls should pass slot="<slot_id>".
Example:
Spawned Rhino 8 as slot
armadillo(port 10500). Passslot="armadillo"on any subsequent rhino-mcp tool call to target it.
Closing the Rhino
When the user is done:
mcp__plugin_rhino-mcp_rhino__close_slot(slot="armadillo")
For N parallel Rhinos, use /launch-rhinos instead — it handles spawn + fan-out + cleanup as one workflow.
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.

launch-rhino is a command published in the GitHub repository hybridlabor-api/bdb-dev-optimized-agent-skills (6 stars, last pushed 3d ago), licensed Apache-2.0. It adds 10 tokens to every session and 367 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to launch-rhino, differing in 0 lines, and is treated as a copy.
