cloud-mail-mcp-manual skillA

cloud-mail-mcp-manual is agent-read markdown (skill) from lingtai-ai/lingtai-kernel: Progressive-disclosure usage manual for the Cloud Mail REST email MCP tool. Read this when you need detail beyond the one-line action descriptions: check/search filters, the compound id (account:emailId) for read, send (needs user credentials), plain vs HTML bodies, accounts/add_user basics, redacted owner-only settings/startup diagnosis, and external-email side-effect caveats. Pulled on demand via action='manual'; you do not need to call it before every send. Calls use the strict LTP-v2 action/.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
