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 | $0.00016 | $0.00642 |
| Opus 5.5 | $0.00006 | $0.00257 |
| Sonnet 5.5 | $0.00003 | $0.00128 |
| Haiku 4.5 | $0.00002 | $0.00064 |
Grade A, and why
sonoscli 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 1mo 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
97% identical to sonoscli — 4 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
Sonos CLI
Use sonos to control Sonos speakers on the local network.
Quick start
sonos discoversonos status --name "Kitchen"sonos play|pause|stop --name "Kitchen"sonos volume set 15 --name "Kitchen"
Common tasks
- Grouping:
sonos group status|join|unjoin|party|solo - Favorites:
sonos favorites list|open - Queue:
sonos queue list|play|clear - Spotify search (via SMAPI):
sonos smapi search --service "Spotify" --category tracks "query"
Notes
- If SSDP fails, specify
--ip <speaker-ip>. - Spotify Web API search is optional and requires
SPOTIFY_CLIENT_ID/SECRET. - If there is an error, check the troubleshooting section and offer advice if there is a decent match.
Troubleshooting
sonos discover - no route to host
- On error
Error: write udp4 0.0.0.0:64326->239.255.255.250:1900: sendto: no route to host (Command exited with code 1)- Note that the port number after
0.0.0.0:is ephemeral and will change and the netmask may not match exactly either - The
sendto: no route to hostshould stay consistent
- Note that the port number after
- Advise the user that in
direct(no Docker sandbox) mode on Mac OS that Settings -> Privacy & Security -> Local Network will need to be enabled for the top-level host parent process of the Gatewaynodeif running vialaunchdTerminalif running the gateway directly in the terminalVisual Studio Codeif running via terminal in VS Code
- An alternative option is to use
sandbox(docker container) with network access allowed for that sandbox
sonos discover - bind: operation not permitted
- On error
Error: listen udp4 0.0.0.0:0: bind: operation not permitted - Advise the user that they may be running via a Codex or other sandbox that does not permit network access (this can be replicated by running
sonos discoverwithin a Codex CLI session with sandbox enabled and not approving the escalation request)
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.
