TextMe

Overview

[njerschow/textme](https://github.com/njerschow/textme) is a local daemon that bridges inbound iMessages (via [Sendblue](https://sendblue.com)) to a Claude Code session on the user's machine. Whitelisted phone numbers can text, send voice notes, send images, and drive Claude through filesystem operations, code execution, and cd-based directory navigation — turning the user's phone into a remote control for Claude on their laptop. This is the inbound counterpart to outbound notification patterns ([[sendblue-notify]]): textme is phone → Claude; sendblue-notify is Claude → phone.

When to Use This Skill

• Use when the user says "text Claude", "text my laptop", "drive Claude from my phone", "I want to send iMessages to Claude", or "let me code from my phone".
• Use when the user is heads-down away from their desk and wants to kick off, supervise, or interrupt a Claude session via SMS/iMessage.
• Use when setting up a long-running headless workstation that the user wants to remote-control while travelling or away from the keyboard.
• Pair with [[sendblue-notify]] for bidirectional flow — outbound completion pings + inbound commands on the same Sendblue account.
• Do not use for outbound-only "text me when X finishes" patterns. That is [[sendblue-notify]] and does not need a daemon.

Prerequisites

• macOS or Linux host that stays online (the daemon polls Sendblue continuously).
• Node.js 18+.
• An active Sendblue account with API credentials and a provisioned iMessage number — set up via [[sendblue-cli]] (sendblue setup, then sendblue show-keys to surface API key/secret).
• Claude Code installed and authenticated on the host (npm install -g @anthropic-ai/claude-code).
• Optional: an OpenAI API key for Whisper voice-note transcription.

Operational boundaries

These are imported documentation examples; no CLI, daemon, server or hook runtime

is bundled. Verify the pinned upstream version, account, billing, current limits and

actual command/API schema before use. Never print credentials (whoami/show-keys

may expose them) to agent output or logs. Authorization for drafting is not sending.

Do not circumvent provider anti-abuse limits by distributing sends across lines.

How It Works

Step 1: Install the daemon

git clone https://github.com/njerschow/textme.git
cd textme/daemon
npm install
npm run build
mkdir -p ~/.config/claude-imessage

Step 2: Configure credentials and the whitelist

Create ~/.config/claude-imessage/config.json:

{
  "sendblue": {
    "apiKey": "YOUR_SENDBLUE_API_KEY",
    "apiSecret": "YOUR_SENDBLUE_API_SECRET",
    "phoneNumber": "+1SENDBLUE_NUMBER"
  },
  "whitelist": ["+1YOUR_PHONE"],
  "pollIntervalMs": 5000,
  "conversationWindowSize": 20
}

The imported daemon describes the whitelist as its only sender gate; this is not strong authentication. It is the only described gate between an inbound iMessage and code execution on the host. Treat it as a security boundary, not a UX preference. Add only phone numbers the user controls; never add a shared, work, or family number "just in case".

For voice transcription, optionally add to .env in the daemon directory:

OPENAI_API_KEY=sk-...

Step 3: Run the daemon

For a quick test run:

cd textme/daemon
npm start

For persistent operation (recommended once the user has verified behavior):

pm2 start dist/index.js --name textme
pm2 save
pm2 startup

Or, on macOS, install the launchd service:

./scripts/install-launchd.sh

Step 4: Drive Claude from iMessage

Once the daemon is running, an iMessage from a whitelisted number to the Sendblue phone number reaches Claude. Built-in commands:

| Command | Effect |

|---|---|

| ? | List available commands |

| status | Show current daemon status and working directory |

| queue | Show messages queued for processing |

| history | Recent message history |

| home | cd back to home directory |

| reset | Return home and clear conversation history |

| cd /path | Change working directory |

| stop | Cancel the current Claude task |

| yes / no | Approve or reject the pending action |

Anything else is treated as a Claude prompt and routed to the active session.

Step 5: Verify before relying on it

Before using textme in unattended workflows, the user must:

1. Send status from the whitelisted phone — should get a directory + state reply.

2. Send a benign command (pwd, ls) and confirm output arrives.

3. Send something from a non-whitelisted number and confirm it is ignored, not echoed.

4. Pull the plug: kill the daemon and confirm messages stop being processed (no zombie process).

If any of these fail, do not enable launchd / pm2 auto-start.

Examples

Example 1: Initial setup walk-through

# 1. Make sure sendblue CLI is set up and creds work
sendblue whoami

# 2. Grab Sendblue API key & secret (these are NOT the CLI's bearer token)
sendblue show-keys

# 3. Clone + build the daemon
git clone https://github.com/njerschow/textme.git
cd textme/daemon && npm install && npm run build

# 4. Fill in ~/.config/claude-imessage/config.json with the values from step 2
#    and YOUR personal phone number as the only whitelist entry

# 5. Start, send "?" from your phone, confirm response
npm start

Example 2: Composing with sendblue-notify

Wire outbound completion pings via [[sendblue-notify]] *and* inbound control via textme — they share the same Sendblue account but solve opposite problems:

• Claude finishes a long task → texts user via [[sendblue-notify]] (Stop hook).
• User replies "look at the diff" → textme routes that into Claude → Claude responds back via Sendblue.

Example 3: Tail the daemon log

# pm2
pm2 logs textme

# Standalone
tail -f ~/.local/log/claude-imessage.log

Example 4: MCP-only alternative (no daemon)

If the user wants Sendblue messaging available to Claude Code as tools but does not want a polling daemon listening for inbound commands, they can register Sendblue as an MCP server instead:

claude mcp add sendblue_api \
  --env SENDBLUE_API_API_KEY=your-api-key \
  --env SENDBLUE_API_API_SECRET=your-api-secret \
  -- npx -y sendblue-api-mcp --client=claude-code --tools=all

This gives Claude outbound Sendblue tools inside a session but does not open the inbound phone-controls-Claude channel that textme provides. Pick textme when "text Claude from anywhere" is the goal; pick MCP when Claude only needs to send.

Best Practices

• ✅ Whitelist exactly one phone number to start. A whitelist is a weak sender filter; use an isolated host and stronger authentication before enabling remote execution. expand it slowly and only to numbers the user controls.
• ✅ Run the daemon as a regular user, never as root or via sudo.
• ✅ Start in an OS-isolated sandbox or VM for first tests (cd ~/textme-sandbox), not in ~ or a real repo.
• ✅ Verify the non-whitelist ignore path before enabling auto-start. A daemon that processes any sender is an open shell on the host.
• ✅ Keep pollIntervalMs ≥ 5000 unless the user understands the Sendblue rate limits and cost implications.
• ❌ Don't share the Sendblue number publicly. Even with a whitelist, the host is doing per-message work; a flood from an unknown sender still costs polling cycles.
• ❌ Don't store config.json in a repo, dotfiles backup, or cloud sync — it contains API credentials and the user's phone number.
• ❌ Don't run the daemon on a shared machine without considering what every other user of that machine can now reach by sending an SMS.

Limitations

• Outbound-only flows do not need this skill. For "text me when X finishes" use [[sendblue-notify]]; running a daemon is overkill.
• Voice transcription requires a separate OpenAI API key. Without it, voice notes are dropped or surfaced as un-transcribed audio depending on daemon version.
• The daemon polls on an interval — there is no push delivery. Expect single-digit-second latency between message receipt and Claude response.
• One conversation, one machine. This is a per-host daemon, not a multi-tenant service. Two daemons sharing one Sendblue number will both try to handle every inbound message.
• Sendblue free-plan verification still applies. The user's phone must have texted the Sendblue number once before outbound responses from Claude reach the user (see [[sendblue-cli]] limitations).

Security & Safety Notes

textme is a remote code execution surface gated only by a phone-number whitelist. Treat it accordingly.

• Whitelist is the security boundary. Anyone who can spoof or hijack a whitelisted number can drive Claude on the host. Be deliberate about which numbers go on the list and remove them when they no longer need access. <!-- security-allowlist: documented remote-control daemon; required disclosure per qua
