Implement +set-dropdown, +update-dropdown, +get-dropdown, and
+delete-dropdown shortcuts wrapping the v2 dataValidation API.
This resolves the issue where multipleValue writes silently
became plain text because the prerequisite dropdown configuration
step was not exposed as a CLI command.
Also add lark-sheets-formula.md reference for Lark-specific formula
rules (ARRAYFORMULA, native array functions, date diff, etc.) and
update the dropdown limitation note in SKILL.md to link to the new
+set-dropdown shortcut.
Document the correct object format for writing formulas, URLs with
text, mentions, and dropdown lists via --values parameter. Add
examples contrasting correct object format vs incorrect plain string.
New capabilities:
1. Alias (send_as) sending for all compose shortcuts (+send, +reply, +reply-all,
+forward, +draft-create, +draft-edit):
- New --mailbox flag separates mailbox routing from sender identity, enabling
alias sending where --mailbox specifies the owning mailbox and --from
specifies the alias address in the From header.
- Example: --mailbox me --from alias@example.com --to bob@example.com
- --mailbox priority: --mailbox > --from > "me"
- --from priority: --from > --mailbox > profile("me")
2. Discovery APIs for available mailboxes and sender addresses:
- accessible_mailboxes: lists all mailboxes the user can access (primary + shared)
- send_as: lists available sender addresses for a mailbox (primary, aliases, mailing lists)
3. Mail rules API:
- user_mailbox.rules resource: create, delete, list, reorder, update
4. Reply-all self-exclusion improvement:
fetchSelfEmailSet now also excludes the --from alias address, preventing the
sender from appearing in the recipient list when replying via an alias.
No breaking changes — omitting --mailbox preserves existing behavior.
* docs(mail): add identity guidance to prefer user over bot for mail APIs
Add an identity selection section to the mail skill documentation,
guiding AI agents to default to --as user when operating on mailboxes.
Bot identity requires the app to have tenant-level mail scopes enabled
in the developer console, which most apps do not.
* docs(mail): clarify identity selection wording and bot scope limits
- Replace ambiguous "默认使用" with "策略上应优先显式使用" to
distinguish policy recommendation from CLI default (auto)
- Note that bot identity only supports read operations; all write
operations (send, reply, forward, draft edit) require user identity
- Rewrite decision rules by read/write classification
Users reported that AI agents sometimes wrote shell scripts to manually
extract and re-decode JSON string fields (e.g. unicode_escape), causing
Chinese character corruption. Add notes to mail skill docs clarifying
that JSON output can be read directly without additional encoding
conversion.
