Email Copilot

Critical Rules

1. ALWAYS read .claude/skills/email-copilot/rules.md before processing ANY emails
2. ALWAYS run date to get current time before processing (for expiry checks, age calculations)
3. NEVER mix email IDs between accounts - IDs are account-specific
4. ALWAYS use label names (e.g., "Finance/Receipts"), never internal IDs (e.g., "Label_6")
5. CHECK account field in output before operations
6. LOG all user-confirmed actions to .claude/skills/email-copilot/action-log.md — IMMEDIATELY in the same tool call batch as execution, NOT after

CLI Alias

All commands use this base (define once per session):

EMAIL="uv run --project .claude/skills/email-copilot python .claude/skills/email-copilot/scripts/email_cli.py"
GMAIL="uv run --project .claude/skills/email-copilot python .claude/skills/email-copilot/gmail_client.py"

Procedure

1. Check Accounts: $EMAIL accounts
2. Load Rules: Read .claude/skills/email-copilot/rules.md (MANDATORY)
3. Review Action Log: Read .claude/skills/email-copilot/action-log.md to identify patterns from recent decisions
4. Process Each Account:
   • $EMAIL -a <account> list -n 100
   • Apply account-appropriate rules (work: strict cleanup; personal: conservative)
5. Classify & Execute:
   • Auto-Trash List matches → trash
   • Expired notifications → trash
   • Receipts/Statements → move to Finance labels
6. Log Actions: When user confirms, execute operations AND update action-log.md in the same tool call batch (parallel Edit + Bash calls)
7. Report & Evolve:
   • Group remaining by account AND category
   • Review action log for recurring patterns → propose rule updates
   • Update rules.md if user agrees

Learning & Evolution

When email doesn't match rules:

• Cold sales → Propose adding sender to Auto-Trash List
• New project → Propose adding Project Keyword
• Recurring newsletter → Propose Newsletter category

Always ask user before updating rules.md.

Multi-Account Notes

• Work accounts: Prioritize project emails, strict cleanup
• Personal accounts: Conservative deletions, preserve receipts
• Each operation outputs account field to identify mailbox

Tips

• Reply-To: reply uses Reply-To header when present (mailing lists)
• GitHub: Check snippet for "approved", "lgtm", bot names
• Safety: If unsure, list in report instead of trashing
• Drafts Workflow: Create draft → User reviews in Gmail → drafts send or manual send

Action Log Format

Log file: .claude/skills/email-copilot/action-log.md

## YYYY-MM-DD

### Trashed
- [account] sender@example.com - "Subject" (reason: auto-trash match / user confirmed)

### Moved
- [account] sender@example.com - "Subject" → Label/Name

### Kept
- [account] sender@example.com - "Subject" (user decision: reason)

### Patterns Identified
- sender@example.com appeared 3x this week → consider adding to auto-trash

Review log before each session to:

1. Identify senders appearing repeatedly → propose Auto-Trash rule
2. Find emails consistently moved to same label → propose filter
3. Track user overrides → adjust rule confidence
