A configuration command for the Lark/Feishu messaging connection used by the claude-lark-plugin. Lark, also called Feishu, is a team messaging and collaboration platform.

Use it to set up Lark/Feishu, check current settings, or change how the plugin handles users, chats, messages, and scheduled scans.

It provides one place to inspect or change connection credentials, limits, filters, message settings, and scheduled-scan options.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.01744
Opus 5	$0.00021	$0.00872
Sonnet 5	$0.00008	$0.00349
Haiku 4.5	$0.00004	$0.00174

Measured 8d ago against content hash 571d82a2d39c, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

configure scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/lark:configure

Manage the claude-lark-plugin configuration stored in ~/.claude/channels/lark/.env.

Arguments passed: $ARGUMENTS

No args — Show current status

Read ~/.claude/channels/lark/.env if it exists.
Display all recognized configuration keys with their current values.
Mask sensitive values:
- LARK_APP_ID: show the first 6 characters, mask the rest
- LARK_APP_SECRET: show the first 3 and last 2 characters, mask the middle
Group the output by category:

Suggest next steps:
- If credentials are missing: "Run /lark:configure <app_id> <app_secret> to set credentials, or /lark:configure setup for full interactive setup."
- If credentials exist: "Configuration looks good. Restart the session or reload plugins to apply changes."

`<app_id> <app_secret>` — Quick credential setup

Treat the first argument as LARK_APP_ID and the second as LARK_APP_SECRET.
Run mkdir -p ~/.claude/channels/lark.
Read the existing .env if present.
Update or append:
- LARK_APP_ID=<app_id>
- LARK_APP_SECRET=<app_secret>
Preserve all other existing keys unchanged.
Write the file back.
Confirm: "Credentials saved to ~/.claude/channels/lark/.env."
Tell the user to restart or reload plugins.

`setup` — Full interactive setup

Walk the user through complete configuration, one question at a time using AskUserQuestion.

Step 1: Credentials

Ask for LARK_APP_ID and LARK_APP_SECRET.

If already set, show masked current values and ask if user wants to update.
If user says "keep" or "skip", preserve existing values.
Explain: these come from the Feishu Open Platform app dashboard.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
