飞书 (Feishu / Lark) through lark-cli

飞书 has an API, and lark-cli (the official CLI from Larksuite) wraps it; this is done with shell, not on the phone's screen. Every call prints JSON: ok says whether it worked, data holds the result, error.message says what went wrong. Read the JSON, never the user's screen.

Is it there?

shell: lark-cli auth status; identities.user.available must be true for anything done in the user's name (their agenda, their messages). If the command is missing, the answer says not_configured, or the user identity is not logged in, say so in one line and stop; setting it up is the user's job, in two steps they run themselves: lark-cli config init --new once (it prints a link that creates the CLI's own 飞书 app under their account), then lark-cli auth login (a link or a QR code to approve; --domain calendar,im,task narrows what it may touch). Do not try to install it, to run config init or to log in for them. In a sandbox the CLI and its login only exist when the user shared them (sandbox.share_read_only / sandbox.share in config.toml); the error then says "command not found"; tell the user which two lines to add.

Reading

• Today's schedule: lark-cli calendar +agenda --as user (a date: --date 2026-09-25; a range with --start / --end).
• Free time for a meeting: lark-cli calendar +freebusy --user-ids ou_… --start … --end ….
• A person: lark-cli contact +search-user --query 张三 --as user → their open_id (ou_…). A group: lark-cli im +chat-search --query 项目群 --as user → chat_id (oc_…). Take the one match; with several, ask the user which with one ask_user, do not guess.
• What was said: lark-cli im +chat-messages-list --chat-id oc_… --as user (a DM: --user-id ou_…; --start-time / --end-time for a window). lark-cli im +messages-search --query 周报 --as user across chats.
• Tasks: lark-cli task +get-my-tasks --as user. A document: lark-cli docs +fetch --doc <url or token> gives its text.
• Add --jq '<expr>' to keep the output small (--jq '.data[] | {summary, start_time}'), and --format table when you want to show a list to the user as is.

Writing

Every write is something the user says to other people. Before the call, show the exact text and the recipient and ask with one ask_user; send only what they approved, word for word.

• A message: lark-cli im +messages-send --chat-id oc_… --text "…" --as user (a DM: --user-id ou_…; longer or formatted: --markdown "…"). Add --idempotency-key <something unique> so a retried command cannot send twice.
• A reply in a thread: lark-cli im +messages-reply --message-id om_… --text "…" --as user.
• An event: lark-cli calendar +create --summary "…" --start 2026-09-25T14:00:00+08:00 --end 2026-09-25T15:00:00+08:00 --attendee-ids ou_a,ou_b --as user.
• A task: lark-cli task +create --summary "…" --due 2026-09-26 --assignee ou_… --as user.
• A document: lark-cli docs +create --title "…" --markdown @notes.md --as user from a file in the workspace.

Commands the CLI marks high-risk-write (deleting an event, removing members, anything with --yes) refuse to run without --yes; add it only after the user has said yes to that very action, and never to a command that was not asked for. Sentinel will show the shell command on an approval card; that is expected.

With the other hands

• 飞书 + 高德: plan the route or check the weather with the amap skill, then put the result in a message or an event description.
• 飞书 + the phone: apps that have no API (12306, 微信, 支付宝) are done with phone_task; the outcome (the train, the payment made) goes to the colleague through lark-cli.
• 飞书 + the workspace: a brief, a comparison, a page you wrote becomes a document with docs +create or an attachment with im +messages-send --file.

Finish

Reply with what was read or done in a few lines: the messages sent (to whom, first words), the event (title, time, attendees), the task (title, due). Do not paste whole chat histories into the answer; give the gist and offer the rest. remember who the user writes to most and which groups matter, so that next time the search is shorter.
