Refactors the contacts system from being embedded in cal_tool.py into a
standalone contacts skill that serves as the single source of truth for
recipient validation across all outbound email paths.
- New skills/contacts/ skill: list, add, delete, resolve commands
- New skills/himalaya/scripts/himalaya.sh wrapper: validates To/Cc/Bcc
recipients against contacts for message send, template send, and
message write commands; passes everything else through unchanged
- cal_tool.py now delegates to contacts.py resolve instead of inline logic
- TOOLS.md updated: agent should use himalaya wrapper, not raw himalaya
Agent hallucinated "xiaojuzi@meta.com" instead of looking up the correct
address from USER.md. Prompting rules can't reliably prevent this, so
recipient validation is now enforced at the tool level.
- Add contact list/add/delete subcommands (vCard .vcf files synced via CardDAV)
- send --to now resolves through contacts: accepts names, name:type, or
known emails; rejects unknown addresses with available contacts shown
- Multi-email contacts supported with type qualifier (e.g. "小橘子:work")
- Adding contacts and sending are separate operations (no chaining)
event delete on a recurring event previously deleted the entire .ics file,
killing the whole series. Now requires --date (adds EXDATE) or --all (deletes
series) for recurring events, refusing to act without either flag.
Add --rrule flag to send with DTSTART/BYDAY validation (RFC 5545).
Add event list (via khal) and event delete (safe single-event removal).
Document safety rules from 2026-03-25 incident: always dry-run recurring
events, never rm .ics files, space out SMTP sends.
- Remove duplicate email rule in TOOLS.md
- Add todo mutations to sync description in TOOLS.md
- Remove METHOD:REQUEST from todo add ICS (no longer emailed)
- Update todo check description in SKILL.md
Remove three redundant email flows since all devices sync via CalDAV:
- Auto-adding mail@luyx.org as attendee on outgoing invites
- Forwarding invites to mail@luyx.org on accept/tentative
- Emailing todos to mail@luyx.org on todo add
