Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by TryCaspian on GitHub. Read the source before you install it.

Installation

Install the Caspian Connect Email AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/TryCaspian/caspian-sdk/tree/main/packages/opencode/src/skills/caspian-connect-email
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/TryCaspian/caspian-sdk.git /tmp/caspian-sdk
mkdir -p .claude/skills
cp -r /tmp/caspian-sdk/packages/opencode/src/skills/caspian-connect-email .claude/skills/caspian-connect-email

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Caspian Connect Email in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Caspian Connect Email on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Caspian Connect Email is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Caspian connect email

Get a Caspian API key (sandbox or existing dashboard key), save it to ~/.config/opencode/caspian.env, connect an email inbox, and enable email in caspian.json channels.

When to use

User asks to connect / set up Caspian email
User runs /caspian:connect-email or /caspian-connect-email
First-time OpenCode + Caspian setup

How

Call caspian_setup_credentials with mode=status.
If not configured, ask the user which path they want (do not invent keys):

A — Instant sandbox (recommended for trying Caspian)
No account. Call caspian_setup_credentials with mode=sandbox.
Writes CASPIAN_API_KEY + CASPIAN_BASE_URL=https://api.trycaspianai.com to ~/.config/opencode/caspian.env (and project .env).

B — Existing Caspian account
Tell them to sign in at https://dashboard.trycaspianai.com/login , open a project, copy the API key, then call caspian_setup_credentials with mode=paste and apiKey=<their key>.

If setup says RESTART REQUIRED, stop and tell them to quit + relaunch OpenCode, then run /caspian:connect-email again.
Call caspian_connections (optional) to show current links.
Call caspian_connect_email (optional displayName).
If the tool says RESTART REQUIRED, tell the user clearly:

Restart OpenCode (quit and relaunch) so the plugin reloads caspian.json and admit includes email.
Do not invent connection ids or addresses. Report tool errors as-is.

Notes

Secrets go in caspian.env / .env — never in caspian.json or chat logs when you can avoid it (the tool masks keys in its output).
CLI (caspian init) is optional; sandbox mint and paste cover the same APIs.
After restart, inbound email should create OpenCode sessions automatically.

Frequently asked questions

What does the Caspian Connect Email AI skill do?

Why use Caspian Connect Email on TypingMind?

Because you install it once and use it with any model. Caspian Connect Email is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Caspian Connect Email in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/TryCaspian/caspian-sdk/tree/main/packages/opencode/src/skills/caspian-connect-email. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Caspian Connect Email?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Caspian Connect Email?

As many as you like. As long as a model supports skills, you can use Caspian Connect Email with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Caspian Connect Email AI skill free?

Yes. It is published on GitHub by TryCaspian under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
