 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.

 We recommend using the Lark/Feishu bot integrated with this tool as a private conversational assistant. Do not add it to group chats or allow other users to interact with it, to avoid abuse of permissions or data leakage.
 
+To reduce the security risks associated with access token theft, the CLI sends a minimal set of risk-control signals with OpenAPI requests made to exact official Feishu/Lark HTTPS domains. These signals are used to help identify anomalous API activity. This protection is enabled by default. The information sent is limited to:
+
+- Operating system type: macOS, Windows, or Linux
+- Device hardware model: for example, Mac17,9
+
+To disable this protection for the current workspace, run:
+
+```bash

+## +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.
