The primary manifest — the file an agent reads to learn what this artifact does.
Use this skill when an agent needs to inspect or manage Trello boards through the bundled MCP server. The skill carries its own server source in assets/source/ and installs it locally on first use.
Before using Trello tools, verify that the local server has been installed.

TRELLO_API_KEY and TRELLO_TOKEN configured.Optional values are TRELLO_BOARD_ID, TRELLO_WORKSPACE_ID, https_proxy, and HTTPS_PROXY.
The install script builds from assets/source/ when Bun is available. If Bun is not available, it falls back to the published package install path and creates a local wrapper at the same build/index.js check path.
