Ghostty — Your Always-On Digital Self#

Ghostty is an always-on AI proxy that acts as you when you're unavailable. It watches your channels, learns your voice, drafts replies, and escalates intelligently.

Core Loop#

text

1. MONITOR   → Spawn sub-agents watching email, calendar, Slack, WhatsApp
2. LEARN     → Build voice profile from your sent messages (ongoing)
3. DRAFT     → When meaningful event detected, draft reply in YOUR voice
4. ROUTE     → Send via the right channel (urgent → WhatsApp, formal → email)
5. ESCALATE  → Only interrupt you when it truly matters

Step 1 — First Time Setup: Build Your Voice Profile#

Before Ghostty can draft as you, it needs to learn your style. Run the profile builder:

text

scripts/profile_builder.py --source <email-folder or messages-export> --output ghostty/voice-profile.md

The builder analyzes:

• Average sentence length and structure
• Common phrases and fillers
• Greeting and sign-off patterns
• Formality level (1-10)
• Preferred punctuation style
• Tone indicators (confident, warm, terse, etc.)

Store the profile at ghostty/voice-profile.md in your workspace. Update it monthly as your style evolves.

Step 2 — Set Up Channel Monitors#

Spawn a persistent sub-agent for each channel you want Ghostty to watch. Use mode="session" so they run continuously.

Email (Gmail/Outlook):

text

sessions_spawn(
  task="You monitor the email inbox for important messages.
  Rules: (1) Only act on emails from people in the PRIORITY_SENDERS list in ghostty/config.md,
  (2) For each important email, draft a reply using the voice profile at ghostty/voice-profile.md,
  (3) Send the draft to the escalation channel (WhatsApp/Signal) with [APPROVE] prefix for one-click send,
  (4) Mark as TODO in ghostty/pending-drafts.md
  Run continuously. Check every 15 minutes.",
  runtime="subagent",
  mode="session",
  label="ghostty-email"
)

WhatsApp/Signal:

text

sessions_spawn(
  task="You monitor WhatsApp messages.
  Rules: (1) Only respond to DND-mode messages or explicit @ghostty mentions,
  (2) Draft replies using voice profile at ghostty/voice-profile.md,
  (3) If sender is in PRIORITY_SENDERS, send directly. Otherwise queue for approval.
  Run continuously.",
  runtime="subagent",
  mode="session",
  label="ghostty-whatsapp"
)

Calendar:

text

sessions_spawn(
  task="You monitor the Google Calendar / Outlook calendar.
  Rules: (1) Alert via WhatsApp 1 hour before any calendar event,
  (2) If a meeting is about to start and you haven't joined, alert again,
  (3) If someone invites you to a meeting and you're not available (based on ghostty/availability.md), draft a polite decline using your voice profile.
  Run continuously.",
  runtime="subagent",
  mode="session",
  label="ghostty-calendar"
)

Step 3 — Escalation Rules#

Edit ghostty/config.md to define:

• PRIORITY_SENDERS — list of people who always get a response
• URGENT_KEYWORDS — words that trigger immediate WhatsApp alert
• IGNORE_SENDERS — newsletters, bots, noise to skip
• RESPONSE_WINDOW_MINUTES — how long before drafting (default: 60)
• APPROVAL_CHANNEL — where to send drafts for approval (default: WhatsApp)

Step 4 — Drafting in Your Voice#

When a monitor detects something worth responding to:

text

1. Read ghostty/voice-profile.md — get style params
2. Read ghostty/config.md — get context (relationship, ongoing projects, preferences)
3. Fetch the incoming message — understand what it's about
4. Draft reply — apply voice profile (tone, length, phrases, formality)
5. If sender is PRIORITY — send directly
6. If not — queue to ghostty/pending-drafts.md and send preview to WhatsApp

Voice drafting rules:

• Short replies: aim for same length as you typically write
• Matching tone: if you use "Hey mate" don't use "Dear Sir"
• Reference context: mention anything ongoing (projects, prior emails)
• Signature: include your sign-off style from the voice profile

Step 5 — One-Click Approval#

When a draft is sent to WhatsApp:

text

[Ghostty] Reply to John re: Q4 proposal

Hey John, yeah happy to jump on Tuesday — 3pm works from my end.
I'll send over the deck beforehand so we can dive straight in.

[APPROVE to send] [EDIT then send] [SKIP]

Respond with "APPROVE" on WhatsApp → Ghostty sends the email/WhatsApp reply.

File Structure#

text

ghostty/
├── voice-profile.md      # Your style fingerprint — generated by profile_builder.py
├── config.md             # Priority senders, keywords, escalation rules
├── availability.md       # When you're reachable, timezone, DND hours
├── pending-drafts.md     # Queue of drafts awaiting approval
└── sent-log.md           # History of what Ghostty sent on your behalf

Reference Files#

• references/voice-profile.md — detailed voice profiling methodology
• references/channel-monitors.md — channel-specific setup (Gmail, WhatsApp, Calendar, Slack)
• references/draft-engine.md — how to draft contextually in your voice
• references/delivery-router.md — escalation logic, urgency routing, approval flows
• scripts/profile_builder.py — analyze sample messages, output voice profile markdown

Safety#

• Ghostty never sends without approval UNLESS the sender is in PRIORITY_SENDERS
• All sent drafts are logged in ghostty/sent-log.md
• DND hours from ghostty/availability.md are respected — no pings during sleep hours
• Review ghostty/pending-drafts.md at least once daily
