At a glance

Wires up an additional phone number onto an already-installed Dial channel, so one NanoClaw install answers SMS and AI voice calls on more than one line.

  • Adding a second phone line to an existing Dial-based agent install
  • SKILL.md covers Pre-flight, Choose the number, Choose the agent and Wire the line, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Giving a NanoClaw install a separate support line alongside a personal one

What it does

This skill adds a number to a Dial channel that is already installed, using a sequence of validated, idempotent steps meant to run identically whether a human or the deterministic skill engine performs them. Each number becomes its own public, threaded messaging group - its platform id is the Dial number itself - with every remote correspondent appearing as a thread inside it, and the agent replies from whichever number a person actually texted.

Before touching anything it confirms Dial is installed and that the multi-number adapter - which routes incoming events by which line they arrived on - is present, directing the operator to reinstall or update skills first if either check fails. It then lists the account's current numbers, tells the operator that purchasing a new number spends account funds, and asks for the chosen number in E.164 format, verifying afterward that the number actually belongs to the signed-in account before wiring it in.

Its steps are written as structured directives with capture, validation and effect annotations, meant to be executed the same way by a human operator or the skill engine rather than freeform instructions.

When your agent uses it

  • Adding a second phone line to an existing Dial-based agent install
  • Giving a NanoClaw install a separate support line alongside a personal one
  • Wiring a newly purchased number into an already-installed Dial channel

Example prompts

  • “Add a second Dial number for our support line.”
  • “Wire this new phone number into the existing Dial channel.”
  • “List the Dial numbers on this account before I add one.”

Requirements

  • Dial channel already installed
  • The Dial CLI

What it can do on your machine

Read from SKILL.md and the folder at commit af699e7. 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 ncrun, ncprompt and ncoperator).

    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

Add A Second Dial Phone Number loads about 1.5k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 445 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
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.

add-dial-number
description
Add another phone number to an existing Dial channel — a second (or third) public line for the agent, so one NanoClaw install answers SMS and AI voice calls on multiple numbers. Use when Dial is already installed and the operator wants an additional number (e.g. a personal line plus a support line). Requires the Dial channel to already be installed (see /add-dial).

Add another Dial number

One NanoClaw install can serve multiple Dial numbers at once. Each number is its own public, threaded line — its own messaging group (platform_id = the Dial number), each remote correspondent a thread inside it — and the agent replies from whichever number a person texted.

This skill is for adding a number to an already-installed Dial channel. Its mechanical steps use nc: directives so an agent and the deterministic skill engine perform the same validated, idempotent workflow.

Pre-flight

Confirm Dial is installed and registered. If this fails, run /add-dial first, then retry:

ncrun
test -f src/channels/dial.ts && grep -q "import './dial.js';" src/channels/index.ts

Adding another number requires the multi-number adapter, which routes on the line each event arrived on (data.to). If this fails, run /update-skills to refresh the installed adapter, rebuild, and retry:

ncrun
grep -q "eventLine" src/channels/dial.ts

Resolve the Dial CLI and the install's user-agent token once for every account request below:

ncrun
command -v dial
ncrun
node -p "'nanoclaw/'+(require('./package.json').version||'unknown')" 2>/dev/null || echo nanoclaw/unknown

Choose the number

List the account's current numbers:

ncrun
DIAL_USER_AGENT={{dial_ua}} "{{dial_path}}" number list --json | jq -r 'if (.numbers|length)==0 then "none" else [.numbers[].number] | join(", ") end'

Tell the operator what is available. Buying a number spends account funds, so leave that explicit: if they need a new one, they should purchase it with dial number purchase --inbound-instruction "…" --explicit-programmatic-consent "<account-holder consent attestation>", then enter the returned number below.

ncoperator
Dial numbers on this account: {{dial_numbers}}. Choose one that is not already wired to NanoClaw. If you need a new number, purchase it first; this may charge the Dial account.
ncprompt
Which Dial number should be added? Enter its E.164 value, for example +14155550123.

Verify that the chosen number belongs to the signed-in account:

ncrun
DIAL_USER_AGENT={{dial_ua}} "{{dial_path}}" number list --json | jq -e --arg number '{{platform_id}}' '.numbers[] | select(.number==$number)' >/dev/null

Choose the agent

List the agent groups:

ncrun
ncl groups list --json | jq -r 'if (.data|length)==0 then "no agent groups yet" else [.data[] | "\(.id) (\(.name))"] | join(", ") end'
ncoperator
Agent groups on this install: {{agent_groups}}.
ncprompt
Which agent group should answer this number? Enter its ag-… id.

Reject a typo before creating anything:

ncrun
ncl groups list --json | jq -e --arg id '{{agent_group_id}}' '.data[] | select(.id==$id)' >/dev/null

Choose a safe display name and who may start conversations on this line. strict admits only known users; public lets anyone who knows the number reach the agent. The choice belongs to this number and does not change existing lines:

ncprompt
What should this line be called? Use letters, numbers, spaces, dots, dashes, or underscores.
ncprompt
Who may text this line: strict or public?
Show full SKILL.md (194 more words)Show less

Wire the line

Create the threaded Dial messaging group. This is idempotent on the number, so a re-run returns an existing row without resetting later policy changes:

ncrun
ncl messaging-groups create --channel-type dial --platform-id {{platform_id}} --is-group 1 --name "{{line_name}}" --unknown-sender-policy {{inbound_access}}

Wire it to the selected agent group. The adapter's declaration supplies the thread and engagement defaults:

ncrun
ncl wirings create --channel-type dial --platform-id {{platform_id}} --agent-group-id {{agent_group_id}}

Restart and verify

Restart the service so the new line is picked up consistently:

ncrun
bash setup/lib/restart.sh

Verify the exact messaging-group and wiring pair exists:

ncrun
mg=$(ncl messaging-groups list --json | jq -er --arg number '{{platform_id}}' '.data[] | select(.channel_type=="dial" and .platform_id==$number) | .id') && ncl wirings list --json | jq -e --arg mg "$mg" --arg ag '{{agent_group_id}}' '.data[] | select(.messaging_group_id==$mg and .agent_group_id==$ag)' >/dev/null

The new number now reaches the selected agent as a separate threaded line, and replies leave from the number that received the message. Existing lines are unchanged.

Troubleshooting

  • The multi-number check fails → run /update-skills, rebuild, and retry.
  • The selected number is rejected → sign in to the correct Dial account or purchase the number first, then copy its exact E.164 value.
  • New texts land in an old line or replies use the wrong number → the running service still has the old adapter; refresh it and restart again.
  • New inbound events never arrive → one dial listen daemon covers the whole account; confirm dial doctor --json reports listen.running: true and dial local-target list --json contains NanoClaw's command target.
  • ncl errors → the host service must be running; ncl connects over a Unix socket.
