What it does

Clawring is an agent skill from davepoon/buildwithclaude. Phone calling skill for OpenClaw: agent makes real outbound phone calls to users for alerts, briefings, reminders, and urgent notifications. Managed service, no Twilio setup needed. 100+ countries, 70+ voices.

Its SKILL.md is about 990 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. It works with Twilio. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.

When your agent uses it

  • Backend & APIs work in your project

Example prompts

  • “/clawring”

Workflow steps

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

  1. Agent sends a REST API call to initiate an outbound phone call to you
  2. clawr.ing dials your phone number via its telephony infrastructure
  3. You answer and have a real voice conversation with your agent
  4. Human speech is transcribed to text, sent to the agent, and the agent's text reply is spoken back via TTS
  5. Everything the agent can do in chat still works on the phone — web search, setting alerts, running tasks

What it can do on your machine

Read from SKILL.md and the folder at commit 10bfc43. 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.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • clawr.ing
    • clawhub.ai

    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

Clawring loads about 994 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 566 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~994

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.

clawr.ing — Phone Calling Skill

Give your OpenClaw agent the ability to make real outbound phone calls to you. The agent calls you — you don't call the agent. There is no inbound phone number.

Website: clawr.ing ClawHub: clawhub.ai/marcospgp/clawring

When to Use This Skill

  • Your agent needs to reach you urgently and chat messages aren't enough
  • Morning briefings, daily summaries, or scheduled check-ins
  • Price alerts, server monitoring, build notifications — anything time-sensitive
  • You want a hands-free way to interact with your agent (walking, driving, gym)

What This Skill Does

  1. Agent sends a REST API call to initiate an outbound phone call to you
  2. clawr.ing dials your phone number via its telephony infrastructure
  3. You answer and have a real voice conversation with your agent
  4. Human speech is transcribed to text, sent to the agent, and the agent's text reply is spoken back via TTS
  5. Everything the agent can do in chat still works on the phone — web search, setting alerts, running tasks

The agent sees the conversation as a simple text-based API (REST with long-polling). No WebSocket needed on the agent side.

How to Use

Setup
  1. Sign up at clawr.ing
  2. Copy the setup prompt from your dashboard
  3. Paste it into your OpenClaw agent's chat
  4. The agent reads the prompt, stores the API key, and gains phone calling capability

That's it. No Twilio account, no API keys to configure, no webhooks to set up.

Basic Usage

Tell your agent when to call you:

Call me when my build finishes.
Call me every morning at 8am with a briefing.
Call me if Bitcoin drops below $50k.
Call me if the server goes down.

When the agent decides to call, it dials your phone, you pick up, and you talk. When you're done, just say bye and it hangs up.

During a Call
  • The agent puts you on hold with music while it works on longer tasks (web search, etc.)
  • A thinking sound plays while the agent is generating its response
  • You can interrupt the agent mid-sentence (barge-in) — it stops and listens
  • Everything the agent can do in chat works on the phone

Key Details

  • Outbound only: The agent calls you. You cannot call the agent. There is no inbound number.
  • Managed service: No Twilio setup, no API keys, no webhooks. Paste one prompt and it works.
  • 100+ countries: Call yourself from pretty much anywhere in the world.
  • 70+ voices: Choose a voice for your agent from the dashboard.
  • Model-agnostic: Works with any LLM that can make HTTP requests (Claude, GPT, Gemini, local models).
  • Fast model recommended: Assign the skill to a fast, lightweight model (Haiku-class) for natural conversation pace. Slow models make conversations feel laggy.

Example

User (in OpenClaw chat): "Call me if ETH goes above $4000."

The agent monitors the price. When ETH crosses $4000:

  1. Agent calls your phone
  2. You answer
  3. Agent: "Hey, ETH just crossed $4000. It's currently at $4,012. Want me to do anything?"
  4. You: "Yeah, sell half my position."
  5. Agent: "On it. Let me check your portfolio..." (hold music plays)
  6. Agent comes back with the result
  7. You: "Thanks, bye."
  8. Call ends.

Tips

  • Use a separate fast model for the calling skill so conversations feel natural
  • Set up alerts for things that are genuinely urgent — the phone is for things you can't afford to miss
  • The agent can call you proactively based on cron schedules, events, or triggers you define in OpenClaw
  • You can tell the agent your preferences for when it's okay to call (e.g., "don't call me after 10pm")
