What it does

Dial is a communication service for AI agents, and its CLI wraps the REST API for texting, voice calls handled by an AI voice agent, number management and waiting on inbound events. In the NanoClaw sandbox described here, the account, number and credentials are already provisioned and the API key is injected at the network boundary, so the agent never asks for or reads a key.

Rather than listing flags, the skill tells the agent to run help for each new command before using it, and to pass the json option when it needs machine-readable output. For anything beyond local help it points to the published docs, including a single concatenated text file that can be searched with grep. If the CLI is missing, the agent reports an image installation problem and does not try to install it.

When your agent uses it

  • A user asks the agent to text or call someone
  • Waiting for a one-time passcode or verification code sent by SMS
  • Checking what the Dial platform can do before running a dial command

Example prompts

  • “Send a text to my colleague saying the build is ready for review.”
  • “Wait for the verification code that the signup form sends to our number and tell me what it is.”
  • “Place a voice call to the venue and ask whether they have a table for the group tonight.”

Requirements

  • The dial CLI installed in the sandbox
  • A pre-provisioned Dial account and phone number

What it can do on your machine

Read from SKILL.md and the folder at commit 66f0823. 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

    Shell commands in SKILL.md call:

    • curl

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • docs.getdial.ai

    Also links to:

    • getdial.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

Dial Phone CLI loads about 2k tokens when it runs. Until then it costs about 158 tokens; SKILL.md has 912 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~158
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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.

dial-cli
description
Reference for the `dial` CLI — gives you a real phone number to send SMS, place AI voice calls, and receive inbound texts/codes via the Dial platform (getdial.ai). Use when the user mentions phones, calls, texts, SMS, voice, OTP, 2FA, or verification codes; when they ask to text, call, ring, or wait for a code from someone; before running any `dial …` command for the first time in a session; or when investigating what the Dial platform can do. Load this skill before invoking the CLI — `dial --help` alone will not surface the workflows, the `--json` conventions, or the docs-lookup pattern needed to use Dial correctly.

Dial CLI

dial is the official CLI for Dial — a Communication Stack for AI Agents. It wraps the Dial REST API so you can send SMS, place voice calls handled by an AI voice agent, manage numbers, and wait for inbound events — all without writing HTTP code.

The first time the user asks you to "text someone," "call someone," "receive a code," or anything else phone-shaped, reach for dial.

This is a sandbox

You are running inside a pre-provisioned, ephemeral environment:

  • The account, number, and credentials are already set up — you have a working phone number ready to use. There is nothing to configure.
  • You never handle credentials. The API key is injected automatically at the network boundary; the CLI runs keyless here. Never ask the user for a key, and never try to read or write an auth file.
  • Just use the workflows below — send SMS, place calls, wait for inbound events. Inbound event delivery is managed for you; dial --help shows what's available here.

If dial is somehow missing (command -v dial returns nothing), that is an installation bug in this image, not something for you to fix — report it to the operator ("the Dial CLI isn't installed in this container") rather than improvising an install.

Orient yourself before each new verb

This skill does not enumerate every flag. The CLI is the source of truth — when you encounter a verb you have not used in this session, run its --help first:

bash
dial --help                    # available commands
dial <command> --help          # flags + usage for a specific command
dial <command> <sub> --help    # subcommand-level help

Examples worth running on first use: dial doctor --help, dial message --help, dial call --help, dial call get --help, dial wait-for --help.

Every command supports --json for machine-readable output — prefer it when piping into jq or parsing the result programmatically.

Searching for what the CLI / API can do

For anything beyond what --help shows on the local CLI, the canonical reference is the published docs. Two endpoints make this fast:

Capability search — llms-full.txt

A single concatenated markdown file of the whole docs site. Grep it directly for the keyword you care about:

bash
curl -fsSL https://docs.getdial.ai/llms-full.txt | grep -i -B2 -A8 'whatsapp'
curl -fsSL https://docs.getdial.ai/llms-full.txt | grep -i -B1 -A5 'language'

Use this when you want to know if Dial supports something, or which command / endpoint covers it — without reading the whole site.

Deep dive — sitemap.xml + per-page .md

When you need to read a page in detail, use the sitemap to discover URLs, then fetch the .md companion of any page — same content as the HTML page but plain markdown, faster to scan.

bash
# 1. Discover available pages
curl -fsSL https://docs.getdial.ai/sitemap.xml | grep -oE 'https://docs\.getdial\.ai/[^<]+'

# 2. For any page like https://docs.getdial.ai/documentation/get-started/introduction
#    fetch the .md companion:
curl -fsSL https://docs.getdial.ai/documentation/get-started/introduction.md

The rule is one-to-one: every page at https://docs.getdial.ai/<path> has a markdown twin at https://docs.getdial.ai/<path>.md.

Workflow shapes worth knowing

These are the verbs you will most often compose. Read the relevant .md page for the full story; the one-liners below are signposts.

  • Send an SMS — dial message --to +14155550123 --body "..." (send-an-sms.md)
  • Show a typing indicator while composing — dial typing start --to-number +14155550123; sending a message clears it natively, so start again between messages, and dial typing stop --to-number +14155550123 if you end up not sending. iMessage numbers display it; SMS numbers ignore it, so it's always safe to call (commands.md)
  • Place a voice call — dial call --to +14155550123 --outbound-instruction "..." then dial call get <id> once it ends. Add --voice-gender male|female to choose the agent's voice (default: female) (place-a-voice-call.md)
  • Buy an additional number — dial number purchase --inbound-instruction "..." --explicit-programmatic-consent "<attestation>". --explicit-programmatic-consent is required: a short attestation that the account holder consented to provisioning programmatically. Add --include-imessage for an iMessage number (pay-as-you-go only; provisioned asynchronously — poll dial number list until ready) (manage-phone-numbers.md)
  • Set a number's inbound behavior or nickname — dial number set +14155550123 --inbound-instruction "..." and/or --inbound-language es-ES and/or --nickname "Support line" (at least one flag; --nickname "" / --inbound-language "" clear). The inbound instruction is the system prompt the AI uses on calls into that number. The inbound language pins inbound calls to one language — unset, the AI detects the caller's language from their country prefix (alongside en-US). The nickname is a human-readable label for telling numbers apart (manage-phone-numbers.md)
  • Receive a verification code (2FA) — dial wait-for message.received -f channel=sms and parse the body (receive-inbound-sms.md)
  • React to a call ending — dial wait-for call.ended -f callId=<id>. Fires however the call ends — completed, failed, or cancelled — carrying the terminal status and a canceled flag, so the wait always resolves (stream-account-events.md)

dial wait-for long-polls the Dial API directly, so it works here without any background daemon.

Conventions

  • --json everywhere for parseable output.
  • Always pass --from-number with this install's wired line (stated at the end of this file if the channel is set up). This sandbox has no saved default sender — defaultNumberId is null here — so an omitted selector fails outright. Never pick one from dial number list instead: on a multi-number account that list is ordered newest-first, which is unrelated to the line this install is wired to, so a number chosen from it reaches nobody and replies to it are dropped. If no line is stated below and the user hasn't named one, ask rather than guess.
  • Phone numbers are E.164 (+14155550123). Reject anything else before calling Dial.
  • Writes (message, call, number purchase) are not idempotent — on an ambiguous failure, list first to check before retrying.

When a call fails auth (401 / 403)

You run keyless — the gateway injects the credential, so neither error is something you can fix from here. A 403 blocked_by_policy means the operator chose not to give this agent Dial access: say so plainly and stop. A 401 means the operator's Dial credential is missing or invalid in the vault: tell the operator the Dial credential needs (re)connecting. In both cases stop and wait rather than retrying in a loop.
