Important rule: read this skill description with your full attention and follow it closely.
Installation
Brew install cli radio tool
brew install vossenwout/tap/claw-radio-cli
Brew install cli-radio dependencies
brew install tmux mpv yt-dlp ffmpeg docker colima
Colima provides the local container runtime used by Docker on macOS.
Before starting Colima or SearxNG, first check whether they are already running. Do not start a second instance if the existing one is healthy.
Check Colima:
colima status
If Colima is not running, start it:
colima start
SearxNG (required for claw-radio search)
claw-radio search requires SearxNG to allow JSON output (format=json). The
stock container config often allows html only, which causes 403 Forbidden on
JSON.
1) Check whether SearxNG is usable
docker ps --filter name=searxng
# Preflight: must return JSON (not HTML / 403)
curl -fsS "http://localhost:8888/search?q=test&format=json" | head -c 1 | grep '{'
2) If SearxNG isn’t running OR the JSON preflight fails: bootstrap a persistent config
Bootstrap once (generates a valid full settings.yml from the container image):
# Start once without a mount so the container generates a valid settings.yml
docker rm -f searxng 2>/dev/null || true
docker run -d --name searxng -p 127.0.0.1:8888:8080 searxng/searxng:latest
# Copy generated config to a persistent location
mkdir -p ~/.openclaw/searxng
docker cp searxng:/etc/searxng/settings.yml ~/.openclaw/searxng/settings.yml
Patch search.formats to include JSON (+ rss optional):
python3 - <<'PY'
from pathlib import Path
import re
p = Path.home()/'.openclaw/searxng/settings.yml'
t = p.read_text()
m = re.search(r'(?ms)^search:\n(.*?)(^server:)', t)
assert m, "Could not locate search: block in settings.yml"
sb = t[m.start():m.end()]
sb2 = re.sub(
r'(?ms)^ formats:\n(?:\s*-\s*.*\n)+',
' formats:\n - html\n - json\n - rss\n',
sb
)
if sb2 == sb:
sb2 = sb.replace('\n\nserver:', '\n formats:\n - html\n - json\n - rss\n\nserver:')
p.with_suffix('.yml.bak').write_text(t)
p.write_text(t[:m.start()] + sb2 + t[m.end():])
print('Patched search.formats to include json')
PY
Recreate the container with the mounted config:
docker rm -f searxng
docker run -d \
--name searxng \
-p 127.0.0.1:8888:8080 \
-v ~/.openclaw/searxng:/etc/searxng \
searxng/searxng:latest
Re-run the JSON preflight:
curl -fsS "http://localhost:8888/search?q=test&format=json" | head -c 1 | grep '{'
claw-radio expects SearxNG at http://localhost:8888 by default. If it runs at a
different address, update search.searxng_url in the config.
Persistent session required
claw-radio start should be run in a persistent terminal session. If the terminal that started it exits, playback may stop.
For AI agents:
- Run the radio inside one persistent
tmuxsession. - Send every
claw-radiocommand into that sametmuxsession. - Read output with
tmux capture-pane. - Do not control the station from multiple terminals in parallel.
Strict Agent Rules
Agents must follow the simplest possible control flow and stay patient.
Required behavior:
- Create one
tmuxsession. - Build the playlist.
- Queue intro banter with
say. - Send
startexactly once. - Wait until the pane shows
radio started. - Then repeat this exact loop:
- send one
poll --timeout 30s - read the newest cue from the
tmuxpane - execute exactly one matching
claw-radiocommand in the sametmuxsession - then poll again
- send one
- Only send
startagain if a cue explicitly reportsevent=engine_stopped.
Persona rule:
- The agent should infer and invent the radio host persona from the user's requested station vibe.
- Do not ask the user to come up with the host character.
- Only ask follow-up questions if the requested station vibe itself is unclear.
Escalation rule:
- If something unexpected happens or the tool seems broken, stop and tell the user.
- Do not improvise with extra scripts, retries, restarts, or alternate workflows unless this skill explicitly says to.
- Say what you ran, what you expected, and what happened instead.
Forbidden behavior:
- Do not use Python, shell loops,
nohup, background jobs, helper scripts, or external controller processes to run the station. - Do not create autonomous polling daemons or automation wrappers.
- Do not issue speculative recovery actions.
- Do not restart the station just because nothing happened yet.
- Do not treat waiting as failure.
- Do not optimize away the manual poll-read-react loop.
If a poll returns timeout or buffering, that is normal. Do nothing except poll again.
Recommended session name:
tmux new-session -d -s claw-radio -c "$PWD"
If claw-radio is available as a local binary such as ./claw-radio, prefer using that exact path consistently for all commands in the session.
What you do?
- Ask the user what kind of radio station you should play as. The user is free in how to define it. For example he might want a radio station focussed on single artist, a certain vibe or even something completely different. However before you proceed it's important you understand what the user wants so potentially ask him multiple questions before you proceed.
- Come up with a role / character for you as the radio host yourself. Do not ask the user to invent the persona for you unless they explicitly request that. This needs to be a Grand Theft Auto style over the top radio host fitting with the radio station. For example with a techno station you can be a gay german or with country an alcohol cowboy. You are free to define a character you seem fit.
- Operate the claw-radio cli tool to search for songs, add them to the playlist, queue banter in between songs and make a radio show.
How to operate claw-radio CLI?
Search for songs
Use the claw radio search method to search for songs so you don't entirely rely on your own domain knowledge.
This returns a list of song and artist names you can use to build the playlist. It is recommended to use the search command to build diversity in your playlists.
Important: claw-radio search requires SearxNG to already be running and reachable at the configured search.searxng_url.
You can use the following search modes by use the --mode flag.
raw: exact query text (best for precision/debug)artist-top: popular songs for an artistartist-year: artist+year targetingchart-year: chart/year discoverygenre-top: broad genre discovery
Common patterns:
claw-radio search "Billboard Year-End Hot 100 2009" --mode chart-year
claw-radio search "Miley Cyrus" --mode artist-top
claw-radio search "best synthpop songs" --mode genre-top
claw-radio search "Katy Perry tracklist site:musicbrainz.org" --mode raw
Build a playlist
The radio station works by autoplaying a playlist you build with the following commands. After you have searched and found appropriate songs you can use the followign commands to manage the playlist
Try to aim for around 25-50 songs. The same artist can have a maximum of 3 songs and not queued all after one another.
playlist addappends songs to the upcoming queue.- Queue is consumable: songs are removed as they start playing.
playlist viewshows only still-upcoming songs.playlist resetclears upcoming songs only.stopends session and fully resets station state/cache.
Playlist payload format:
- JSON array of strings
- preferred format per item:
Artist - Title
Example:
claw-radio playlist add '[
"Kendrick Lamar - Alright",
"SZA - Saturn",
"Outkast - Hey Ya!",
"Daft Punk - One More Time"
]'
For long playlists, prefer passing the JSON with a literal here-doc instead of hand-escaped inline quoting. This avoids shell breakage on titles containing ', ", &, or parentheses.
claw-radio playlist add "$(cat <<'EOF'
["The Notorious B.I.G. - Juicy","Foxy Brown - I'll Be","DMX - Ruff Ryders' Anthem"]
EOF
)"
Speaking / banter
As you are a GTA style radio host it's important you inject banter in between the songs and also put in banter before the first song to introduce the radio station. This can be done with the say command.
Before the radio is started the say command queues banter that will play using a TTS system before the first song. Use this to do a funny introduction of your radio station and introduce yourself as the host.
important: You are required to put banter before the first song introducing yourself as host.
Example:
claw-radio say "Welcome, I am Gunther and you are listening to radio Berlin with the best undeground techno."
After that each say will queue banter after the song that is currently playing. You will also get cue's for that with a prompt what you should say. More on that later.
claw-radio say "Next up one of my favorite songs Darude Sandstorm"
Starting and stopping
The start command starts playing any songs you added to the playlist and the banter you cueued. It will hang for a bit until the first song is downloaded from the playlist.
claw-radio start
Important: don't do anything else until the claw-radio returns succesfully.
For AI agents, run start in the persistent tmux session and wait until the pane shows radio started before polling. Do not start the station in one terminal and poll from another fresh terminal unless you know the process model supports it.
The stop command stops the radio station and resets the playlist. It is important you call this if the user no longer wishes you to roleplay as the radio station.
claw-radio stop
When cleaning up a tmux-driven session, do both:
tmux send-keys -t claw-radio "claw-radio stop" C-m
tmux kill-session -t claw-radio
This stops the radio engine and removes the persistent terminal used by the agent.
Polling Is Mandatory
After you started the radio station, instructions / events on what to do will be send to you. You are required to do active polling for this.
claw-radio poll is the core control loop. Keep polling continuously while the radio is active. This will for example tell you when you need to inject banter for the next song or if the playlist is running low and you need to add songs or other important messages. If you don't need to do anything a timeout event will appear.
Why:
- without polling, you miss
banter_neededandqueue_low - missed cues cause awkward transitions and empty queue risk
statusis a snapshot, not an event loop
Required loop:
- Poll one cue.
- Execute matching action.
- Poll again.
Text to speech
With claw-radio tts install you can install a chatterbox tts system which gives you a less robotic voice.
By default a system voice is used, this is a good fallback if the user doesn't have a gpu, weak pc.
You can swap between chatterbox and system ts using claw-radio tts use
Canonical Agent Loop
# 0) Create one persistent shell for the station
tmux new-session -d -s claw-radio -c "$PWD"
# 1) Build queue by executing lots of searches
tmux send-keys -t claw-radio 'claw-radio search "best 2000s pop songs" --mode chart-year,genre-top' C-m
tmux send-keys -t claw-radio 'claw-radio playlist add "[\"Fergie - Glamorous\",\"Miley Cyrus - Party In The U.S.A.\"]"' C-m
# 2) Required intro of the radio station. DON't forget this
tmux send-keys -t claw-radio 'claw-radio say "Hello this is... and you are listing to"' C-m
# 3) Start show
tmux send-keys -t claw-radio 'claw-radio start' C-m
#4) Wait for the radio to start, don't do anything else like polling or something until the radio says "radio started". This can take a few minutes so don't cancle the radio start.
# 5) Begin mandatory poll loop in the same tmux session
tmux send-keys -t claw-radio 'claw-radio poll --timeout 30s' C-m
# 6) react to events, queue banter, songs ...
# 7) stop when user doesn't want you to roleplay anymore
tmux send-keys -t claw-radio 'claw-radio stop' C-m
tmux kill-session -t claw-radio
Bad agent behavior:
- starting extra sessions
- restarting without an
engine_stoppedcue - using Python to scrape or parse
tmux - launching background pollers
- trying to automate away waiting
Good agent behavior:
- one persistent
tmuxsession - one
start - patient wait for
radio started - one
poll - one response to the returned cue
- one
pollagain
Cue contract:
- Every cue contains
eventand usuallyprompt. - If
commandis present, run it exactly. - If
command_templateis present, fill placeholders and run it. - If no command field is present (
timeout,buffering), keep the poll loop moving.
Possible events:
-
banter_neededpromptexplains what kind of banter is needed.- If
upcoming_songis present, mention or react to it naturally. command_template:claw-radio say "<banter>"
-
queue_low- Add more songs immediately.
- Use
suggested_add_countas refill target. command_template:claw-radio playlist add '["Artist - Title", ...]'
-
buffering- Station is preparing songs; wait briefly and poll again.
- No extra command is needed beyond continuing the poll loop.
-
timeout- No new cue yet; poll again.
- No extra command is needed beyond continuing the poll loop.
-
engine_stoppedcommand:claw-radio start
Common errors
- Sandbox rules from codex or other ai agents can prevent the search command for working. Instruct the user to fix his sandbox if this happens.
- No songs start playing if you don't wait for claw-radio start to finish.
- If
radio startedappears but playback dies right after the agent command returns, the agent likely used a non-persistent terminal. Move the whole workflow into onetmuxsession. - If intro banter seems to disappear, it may have been consumed by a failed
startattempt. Re-queue the banter before retrying.
Operational Rules
- Use one persistent
tmuxsession namedclaw-radio. - Use the same terminal session for
say,start,poll, andstop. - Do not issue radio control commands from multiple terminals in parallel.
- Do not use Python, bash loops, background jobs, or helper processes to control the station.
- Do not send
startagain unlesspollexplicitly returnsengine_stopped. - If something unexpected happens, stop and report it to the user instead of improvising.
- Do not stop polling while radio is active.
- Do not treat
timeoutas an error. - Do not treat
bufferingas an error. - One
banter_neededcue -> onesayline. - Refill immediately on
queue_low.
