Operant

Voice-driven autonomous development pipeline for Claude Code. Phone calls become shipped features.

What it does

Operant turns a phone call into a complete development cycle. You describe what you want built, and Operant drives it through spec writing, implementation, automated auditing, and a live demo -- all inside Claude Code.

Pipeline stages: Call -> Triage -> Spec (Intent, HLD, ADR, Implementation) -> Build -> Audit -> Demo -> Confirmation

Each stage has human gates: you review and approve before the pipeline advances.

Install

# Add the operant marketplace (one-time)
claude plugin marketplace add esxr/operant

# Install the plugin
claude plugin install operant

Quick start

Free mode (mock voice, no API keys needed)

1. Install the plugin (see above)
2. Restart Claude Code
3. Run /process with a trigger file, or use /start and /stop to manage the voice server

The plugin runs in mock mode by default -- it simulates voice calls locally so you can try the full pipeline without any external accounts.

Paid mode (real voice calls via Retell.ai)

1. Sign up at operantlabs.com
2. Get your API key from the dashboard
3. Run /activate <your-api-key> in Claude Code
4. Run /start to spin up the voice pipeline

Commands

Command	Description
/process [trigger-file]	Manually process a call trigger through the pipeline

/start	Start the voice pipeline (webhook server + tunnel + Retell registration)
/stop	Stop the voice pipeline
/whitelist	Manage caller whitelist (list, add, remove)
/activate [api-key]	Activate paid cloud mode
