The skill above teaches agents to build with GRID's packages. For agents to use spreadsheets — load, read, edit, and recalculate .xlsx files — this repo also ships an agent-tools plugin: the @grid-is/agent-tools MCP server bundled with a spreadsheet skill. The MCP server itself works with any MCP-capable harness; see the agent-tools docs for running it standalone.

To install the plugin in Claude Code:

claude plugin marketplace add GRID-is/skills
claude plugin install agent-tools@grid

To install the plugin in Codex:

codex plugin marketplace add GRID-is/skills
codex plugin add agent-tools@grid
