preview_embed_card_query

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavior. It states 'preview query results', which implies a read-only operation, but does not clarify side effects, rate limits, or what 'preview' returns (e.g., sample data vs. full results). This is minimal behavioral disclosure for a tool with no annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that conveys the essential purpose and constraint without extraneous words. It is appropriately sized for the tool's simplicity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has one parameter and no output schema. The description covers the core purpose and admin restriction, but it omits details about the output format (e.g., is it a table of rows? a count?). Given the low complexity, it is minimally adequate but could be more informative.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has one parameter 'token' with description 'Preview embed token', but the tool description adds no additional meaning or context for this parameter. With 0% schema description coverage (as reported), the description should compensate, but it does not mention parameters at all.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'preview', the resource 'embedded card', and the context 'by token from Metabase (admin only)'. It distinguishes the admin-only constraint, but doesn't explicitly differentiate from the sibling tool 'get_embed_card_query'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions 'admin only', which is a prerequisite, but provides no guidance on when to use this tool versus alternatives like 'get_embed_card_query' or 'run_preview_embed_card_pivot_query'. No exclusions or usage scenarios are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
