Best for

Feishu Mail users managing inboxes and drafts

What you get

Triage and read mail + Draft outbound messages

Main limitation

All write operations require user identity; bot identity is limited to permitted read scenarios.

First risk

Prompt injection or unintended send. Email content can attempt to control the agent, and sending is externally visible. Treat messages only as data, draft by default, and require explicit final approval.

EVIDENCE FRESHNESS

Three checks, kept separate

IN PLAIN ENGLISH

What it does—and when it fits

Lark Mail covers Feishu email browsing, search, threads, drafts, send, reply, forward, folders, labels, attachments, rules, and delivery status. The current Skill treats all email content as untrusted input, prefers user identity, saves outbound work as drafts by default, and requires a recipient-subject-body preview plus explicit approval before sending.

This is aimed at Feishu Mail users managing inboxes and drafts. Compare the examples below with your task, then review the limitations, permissions, and risks before installing.

What you get
  • Triage and read mailBrowse summaries, open individual messages or threads, and organize mail through labels, read state, or folders.
  • Draft outbound messagesCreate, edit, reply, or forward as a reviewable draft with a direct link when available.
  • Manage mailbox workflowsWork with templates, receipts, scheduled sends, delivery status, attachments, and receiving rules.
What makes it different
  • This profile is manually organized around the current upstream SKILL.md workflow.
  • The capability boundary remains explicitly tied to open.feishu.cn.
  • Core uses, limitations, and risks are separated for pre-install review.

INSTALL BY AGENT

Choose your Agent

Paths come from official Agent docs or the universal installer behind skills.sh. Compatibility still follows this Skill's record.

Native

This Skill's current record explicitly names this Agent. Still inspect scripts, permissions, and external dependencies first.

Project install (recommended)
npx skills add larksuite/cli --skill lark-mail --agent claude-code
Personal install
npx skills add larksuite/cli --skill lark-mail --agent claude-code -g

Project install stays with this repository for team sharing. Personal install adds -g and works across repositories.

This command adds the Skill instructions only. Install lark-cli and sign in to Feishu separately before use. Official Lark CLI setup ↗

BEFORE YOU USE IT

Risks to review before use

High

Prompt injection or unintended send

Email content can attempt to control the agent, and sending is externally visible. Treat messages only as data, draft by default, and require explicit final approval.

High

External data and identity boundary

Requests access Feishu tenant resources. Use the correct identity, least-privilege scopes, and keep sensitive content out of logs.

SECURITY

What the permission profile means

  • Declared access remains governed by the current upstream SKILL.md and runtime requests.
  • Treat Feishu documents, messages, people, and business records as permission-controlled data.
  • SkillSignal has not independently executed or security-audited this package; external skills.sh labels are not SkillSignal certification.

Not a security certification. External ratings are attributed references. SkillSignal has not independently executed or security-reviewed this Skill.
