# Check templates

Each Skill is also a prompt with the same name. See [Guided checks](https://ai.solarsens.co/docs/concepts/skills.md) for the list and for an example question for each Skill. You can also ask questions in normal language and include the Plant, date range, timezone, and decision you want to review.

The prompts are served when the Worker sets `MCP_PROMPTS` to `"true"`, as production does. Each prompt requires all tools in its procedure to be served. The prompts call no tool. The assistant runs the procedure with the tools the server lists.

Your AI tool shows the arguments of each prompt and their descriptions. Claude Code shows a prompt as `/mcp__<server name>__<prompt name>`, for example `/mcp__solarsens__plant-performance-review`.

A `date` argument must be a Plant-local day as `YYYY-MM-DD`, for example `2026-10-09`. The server rejects an invalid calendar date or a date in another format, for example `9 Oct 2026`. Some AI tools show only "Failed to attach prompt" for this error.

See [Questions to copy](https://ai.solarsens.co/docs/useful-prompts.md) for safe examples.
