get_preview_embed_card_tile

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

No annotations exist, so the description must carry the full burden. It only states 'get a map tile' without disclosing behavior such as what the tile represents, expected response format, or side effects. This is insufficient for a tool with 4 parameters and no output schema.

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, which is concise but lacks structure. No additional details or headings are provided, making it overly minimal for a tool of this complexity.

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?

Given the nested input, 4 parameters, no output schema, and many sibling tile tools, the description is severely incomplete. It fails to explain return values, coordinate system, or how to construct the input object correctly.

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?

Schema description coverage is 0% for the nested parameters (token, zoom, x, y). The description adds no meaning to these parameters, leaving the agent to infer their roles. The token's purpose, coordinate bounds, and zoom levels are unspecified.

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 states the tool gets a map tile for a preview embedded card, specifying the resource and action. However, it does not differentiate from sibling tools like get_embed_card_tile or get_preview_embed_dashboard_tile, leaving ambiguity about its unique scope.

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?

No guidelines provided on when to use this tool versus alternatives. The description lacks context for usage scenarios, prerequisites, or exclusions.

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