 Program output (JSON envelopes) goes to stdout. Progress, warnings, hints go to stderr. Mixing them corrupts pipe chains.

-### Typed data over loose maps
-
-Parse `map[string]interface{}` into a typed struct at the boundary — one projection function per shape — and let everything downstream consume struct fields, not string keys. A typo'd map key compiles fine and fails at runtime, which an agent then debugs blind.
-
-Use distinct types when two values could be swapped silently: see `internal/meta.Token` — a bare string compiles on either side of a string/string signature, a distinct type does not.
-
-Legacy loose-map code exists in older paths. Match its call sites when touching it, but do not copy the pattern into new code.
-
-### Transcribe faithfully — no silent fallbacks
-
-When code echoes input onward (request previews, transformations, proxies), transcribe verbatim. A `default:` branch that coerces unrecognized input into a plausible value ("unknown HTTP verb → GET") makes the output lie, and an agent reasons from the lie.
-
-The same rule applies to flag combinations and internal wiring: if a requested option cannot be honored, return a typed validation error — never silently substitute another behavior and exit 0. Silent guesses (defaulting a missing identity, discarding writes on a nil writer) are bugs even when every current caller happens to avoid them.

 ```

-## +search-bot
-Search bots (apps) by keyword. Pass `--query` or `--queries`; use `--chat-ids` to search within specific chats.
-
-### Skills
- lark-contact/references/lark-contact-search-bot.md
-
-### Avoid when
- Looking for a person rather than a bot → use [[+search-user]]
- Running as a bot — this shortcut is user-only
-
-### Tips
- `has_more=true` means the search is incomplete; refine the keyword or search scope instead of paginating
-
-### Examples
-
-**Find bots by keyword**
-```bash
-lark-cli contact +search-bot --query "会议助手" --as user
-```
-
-**Search inside one chat**
-```bash
-lark-cli contact +search-bot --query "助手" --chat-ids "oc_3a8b****6a7b" --as user
-```
-
-**Find bots you've chatted with**
-```bash
-lark-cli contact +search-bot --query "助手" --has-chatted --as user
-```
-
-**Search several bot keywords in one call**
-```bash
-lark-cli contact +search-bot --queries "会议助手,日报助手,审批助手" --as user
-```
-
 ## +get-user
 Fetch one user's profile by id, or your own with --user-id omitted. Use it under bot identity — `+search-user` is user-only.

-Key:         card.action.trigger
-Description: Triggered when a user interacts with an interactive card (button click, form submit, dropdown select, etc.). Output includes: token (valid 30 min, max 2 updates), action details (tag, value, name, form_value), and card_content (original card in userDSL text format, auto-fetched at consume time). To update the card: parse card_content to understand the current state, construct the new card JSON, then call `lark-cli api POST /open-apis/interactive/v1/card/update` with the token (see lark-im-card-action-reply.md).
