What it does

Twilio Inbound Voice is an agent skill from automateyournetwork/netclaw. Handle inbound Twilio voice conversations for network status and operational requests. Use for the inbound voice channel and its caller checks.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Webhooks. It works with Twilio and Model Context Protocol. The repository describes itself as: An AI agent that claws through your network. The licence is Apache-2.0.

When your agent uses it

  • The inbound voice channel and its caller checks
  • Tasks that involve Webhooks

Example prompts

  • “/twilio-inbound-voice”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Signature Validation: All webhooks validated via Twilio signature
  2. Whitelist Authentication: Caller ID must be whitelisted
  3. Content Sanitization: No IPs, credentials in spoken output
  4. Audit Trail: Full transcript logged

What it can do on your machine

Read from SKILL.md and the folder at commit aa90e7d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are xml).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Twilio Inbound Voice loads about 1.5k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 305 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Feature: 042-twilio-voice-mcp Priority: P2 User Stories: US5 (Inbound Conversations), US6 (Voice Commands)

Purpose

Enable John to call NetClaw's Twilio number and have a bidirectional voice conversation for status queries and network commands.

Trigger Conditions

This skill activates when:

  1. Inbound Call Received
    • Call from whitelisted number ([WHITELIST_NUMBER])
    • Caller ID authenticated

Architecture

John's Phone
    │

Twilio (Inbound Call)

Webhook: POST /webhooks/twilio/voice
    │
    ├─► Authenticate Caller ID
    │       └─► Not whitelisted? → Reject with message
    │
    ├─► Generate Greeting TwiML
    │       └─► "Hello John, this is NetClaw. How can I help?"

    └─► Start Media Stream

            ├─► Text → Claude → Response
            │
            └─► Response → Twilio TTS → Audio Out

Workflow

Inbound Call Flow

    ├─► Twilio sends webhook to NetClaw

Webhook Endpoints

POST /webhooks/twilio/voice

Initial call handler - returns TwiML.

Request: Twilio form-encoded data (CallSid, From, To, etc.)

Response (authenticated):

xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Say voice="Polly.Matthew">Hello John, this is NetClaw. How can I help you?</Say>
  <Connect>
    <Stream url="wss://your-server/webhooks/twilio/media-stream" />
  </Connect>
</Response>

Response (rejected):

xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Say voice="Polly.Matthew">This number is not authorized to call NetClaw. Goodbye.</Say>
  <Hangup />
</Response>
WebSocket /webhooks/twilio/media-stream

Real-time bidirectional audio stream.

Inbound Events:

  • start: Call connected, media format info
  • media: Audio chunk (mulaw, 8kHz, base64)
  • stop: Call ended

Outbound Events:

  • media: Response audio chunk

Voice Commands (US6)

John can issue network commands during the call:

Query Commands (Safe)
  • "What's the status of my network?"
  • "Are there any active incidents?"
  • "Show me BGP neighbors on router-1"
  • "What's the CPU on the firewall?"
Action Commands (Require Confirmation)
  • "Run a health check on the core routers"
  • "Restart the monitoring agent"
  • "Clear the interface counters"
Confirmation Flow
John: "Restart the monitoring agent"
NetClaw: "You want me to restart the monitoring agent. Say 'yes' to confirm or 'no' to cancel."
John: "Yes"
NetClaw: "Restarting monitoring agent... Done. Agent is now running."

Guardrails

  • Caller ID Authentication: Must be in whitelist
  • Content Sanitization: Response sanitized before TTS
  • Command Confirmation: Impactful actions require verbal "yes"
  • Session Timeout: Max 15 minutes per call
  • Logging: Full transcript logged to Memory MCP
