greybox-cloud Claude skills

Claude Code plugins/skills for greybox-cloud customers. Each skill gives Claude richer context on how to use the MCP tools running inside your per-user Greybox.

Install

In any Claude Code surface (CLI, VS Code, Desktop), paste these two lines into the prompt:

/plugin marketplace add GreyhavenHQ/greybox-cloud-skills
/plugin install dataindex-connectors@greybox-skills

That's it. Claude Code now loads the skill content into context whenever you ask about indexed data, ingesters, or DataIndex queries.

Plugins

Plugin	What it does
dataindex-connectors	Operate DataIndex ingesters (gmail, calendar, slack, contactdb, api_document); query indexed entities via REST or MCP.

Cursor

Each plugin also ships a Cursor-compatible .mdc rule under plugins/<plugin>/cursor/. To install in your current project:

mkdir -p .cursor/rules && curl -fsSL https://raw.githubusercontent.com/GreyhavenHQ/greybox-cloud-skills/main/plugins/dataindex-connectors/cursor/dataindex-connectors.mdc -o .cursor/rules/dataindex-connectors.mdc

Cursor will auto-load it the next time the agent runs in this project. For global use, copy the file's body into Cursor → Settings → Rules → User Rules.

(The rule file is too large for Cursor's cursor:// deeplink — 8 KB URL-encoded cap — so a curl one-liner is the cleanest install path.)

Update / remove

/plugin marketplace update greybox-skills
/plugin uninstall dataindex-connectors@greybox-skills

Layout

.claude-plugin/marketplace.json               ← marketplace manifest
plugins/<plugin>/.claude-plugin/plugin.json   ← per-plugin manifest
plugins/<plugin>/skills/<skill>/SKILL.md      ← skill content

To add a new plugin: create a directory under plugins/, drop a plugin.json + skills/<name>/SKILL.md, and append an entry to .claude-plugin/marketplace.json's plugins array.
