Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

email-to-calendar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 45 executable files (scripts/activity_log.sh, scripts/add_pending.sh, scripts/calendar_delete.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CRITICAL RULES - READ BEFORE PROCESSING ANY EMAIL

  1. NEVER CALL gog DIRECTLY - ALWAYS use wrapper scripts (create_event.sh, email_read.sh, etc.). Direct gog calls bypass tracking and cause duplicates. THIS IS NON-NEGOTIABLE.
  2. IGNORE CALENDAR NOTIFICATIONS - DO NOT process emails from [email protected] (Accepted:, Declined:, Tentative:, etc.). These are responses to existing invites, NOT new events. Run process_calendar_replies.sh to archive them.
  3. ALWAYS ASK BEFORE CREATING - Never create calendar events without explicit user confirmation in the current conversation
  4. CHECK IF ALREADY PROCESSED - Before processing any email, check processed_emails in index.json
  5. READ CONFIG FIRST - Load and apply ignore_patterns and auto_create_patterns before presenting events
  6. READ MEMORY.MD - Check for user preferences stored from previous sessions
  7. INCLUDE ALL CONFIGURED ATTENDEES - When creating/updating/deleting events, always include attendees from config with --attendees flag (and --send-updates all if supported)
  8. CHECK TRACKED EVENTS FIRST - Use lookup_event.sh --email-id to find existing events before calendar search (faster, more reliable)
  9. TRACK ALL CREATED EVENTS - The create_event.sh script automatically tracks events; use tracked IDs for updates/deletions
  10. SHOW DAY-OF-WEEK - Always include the day of week when presenting events for user verification

FORBIDDEN: DO NOT USE gog COMMANDS DIRECTLY

WRONG: gog calendar create ... or gog gmail ... RIGHT: "$SCRIPTS_DIR/create_event.sh" ... or "$SCRIPTS_DIR/email_read.sh" ...

Direct CLI calls bypass event tracking, break duplicate detection, and cause duplicate events. ALL operations MUST go through the wrapper scripts in scripts/.

Email to Calendar Skill

Extract calendar events and action items from emails, present them for review, and create/update calendar events with duplicate detection and undo support.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
