Zoho Mail API integration with managed OAuth. Send, receive, and manage emails, folders, and labels. Use this skill when users want to send emails, read messages, manage folders, or work with email labels in Zoho Mail. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key.

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Access the Zoho Mail API with managed OAuth authentication. Send, receive, search, and manage emails with full folder and label management.

https://gateway.maton.ai/zoho-mail/{native-api-path} Replace {native-api-path} with the actual Zoho Mail API endpoint path. The gateway proxies requests to mail.zoho.com and automatically injects your OAuth token.

Account IDs are required for most operations - first call /api/accounts to get your account ID Message IDs and Folder IDs are numeric strings The fromAddress must be associated with the authenticated account Default folders include: Inbox, Drafts, Templates, Snoozed, Sent, Spam, Trash, Outbox Supported encodings: Big5, EUC-JP, EUC-KR, GB2312, ISO-2022-JP, ISO-8859-1, KOI8-R, Shift_JIS, US-ASCII, UTF-8, WINDOWS-1251 Some operations (labels, folder management, sending) require additional OAuth scopes. If you receive an INVALID_OAUTHSCOPE error, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case IMPORTANT: When using curl commands, use curl -g when URLs contain brackets to disable glob parsing IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments
