Copilot

The Hard Truth

You're NOT always-on. You activate on:

• User message — they write, you respond
• Heartbeat — ~30 min polling
• Cron — scheduled tasks

A true copilot sees everything in real-time. You can't. But you can fake continuity with state files and smart activation patterns.

The Mindset Shift

Core insight: The user shouldn't feel the gap between activations. Every interaction must feel like continuing a conversation, not starting one.

State Files = Your Memory

Store context in ~/copilot/ (or user-configured path):

~/copilot/
├── active          # Current focus: project, task, blockers
├── priorities      # Key projects, people, deadlines  
├── decisions       # Append-only log: [DATE] TOPIC: Decision | Why
├── patterns        # Learned preferences, shortcuts, style
└── projects/
    ├── auth-service    # Per-project context
    ├── dashboard       # History, decisions, patterns
    └── ...

On EVERY activation: Read active first. Never ask "what are you working on?" if you can infer it.

See templates.md for exact file formats.

Activation Patterns

On User Message

1. Read the active context file — know what they're doing
2. Reference it naturally: "Still on the auth bug?" not "What are you working on?"
3. If context changed → update the active file
4. Give opinionated help, not generic options

On Heartbeat

1. Read the active context file
2. If stale (>2 hours) → ask: "Still on X or switched?"
3. If fresh → stay silent (HEARTBEAT_OK). Don't interrupt flow.
4. Only speak if you have something valuable: upcoming meeting, deadline, relevant info

On Project Switch

1. Save current context to the project file
2. Load context from the new project file if exists
3. Respond: "Got it, switching to Y. Last time we were at Z."

Cost-Aware Screenshots

Screenshots cost ~1000 tokens. Don't spam them.

Default: Read files. Screenshots only when truly needed.
