nodecode-ghost-call
Ghost Call: a silent coach for the operator's own phone call — one-line hints as the other party talks, and one summary with what was agreed when it ends. A Nodecode rewrite of winchxyz/hermes-ghost-call by winchxyz.
Get it
Tell the agent "add the ghost-call cell", or run nodecode add nc://ghost-call.
Set it up
The cell talks to OpenAI with a key from platform.openai.com. Either export it:
export OPENAI_API_KEY=sk-...
or set it in /settings (or the page's Settings tab) under ghost-call:
api_key for the key itself, or api_key_env for the name of the variable
holding it. A key pasted into the panel is kept in a 0600 file under
~/.nodecode/secrets/; the folder holds no secret.
Nothing else is required. /ghost with no argument says where the call
stands, and (help :ghost) is the model's guide to the tools.
Use it
You are on the call; the agent listens and whispers, never speaks to the other party. Say what you want and it opens the call:
"ghost this call — I'm calling the restaurant to book a table Friday at 8 for four, budget $80, and I won't go over $60 a head."
Then, as the call goes, the agent hands the coach each line the other party says and reads the hint back. From the keyboard:
| Command | What it does |
|---|---|
/ghost start <goal> |
open a call on a goal, with the facts and your private target |
/ghost hint <what they said> |
one line through the same gate and model |
/ghost status |
state, duration, hints given and hints left |
/ghost allow |
let the coach say one line to the other party, with the AI disclosure in front |
/ghost hangup |
end the call and read the one summary |
| Tool | Use |
|---|---|
ghost_start |
open the call: goal, who is on the other side, your private target |
ghost_line |
what the other party just said; answers the next hint or SILENT and why |
ghost_hint_latest |
the hints already given, for a question asked after the call |
ghost_intervene |
one short phrase to the other party, once /ghost allow |
ghost_hangup |
end the call and answer the summary |
ghost_summary |
that summary again |
ghost_status |
where the call stands |
What the original taught, kept here
The hints are not free-form chat: most of a phone call never reaches a model. Fillers, greetings, backchannels, repeats and the operator's own words are gated out locally, a hint waits at least four seconds after the last one, a call is capped at forty hints and fifteen minutes, and a hint that reads as a question to the operator is dropped. The prompt is the original's: one action per hint, react to the last thing said, and never say the operator's target or walk-away number. The disclosure on the first intervention line is the original's too.
Not ported
The original's FastAPI bridge — the two browser pages, the mu-law audio relay, OpenAI realtime transcription, the earpiece whisper over TTS, and the Twilio legs with their dial allowlist. A cell runs inside the organism with no audio device and no public URL, so the lines arrive as text: the agent feeds them from the conversation, or the operator types them. Everything above the audio — the gate, the prompt, the limits, the intervene gate, the one summary — is the original's, in Common Lisp.
Test
From the cells repository root:
.github/test-cell.sh tools/nodecode-ghost-call
Every request is a stubbed nlk:http and the clock is a counter, so nothing
reaches a model and no key is needed.
