gta-map-screenshot

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

No annotations are provided, so the description carries full burden. It clearly states the tool captures a screenshot and returns the image inline, indicating a read-only operation. However, it lacks details on data freshness (always today's) or error handling for invalid categories.

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?

Two sentences, zero wasted words. The description is front-loaded with the action and resource, followed by examples and output format. Highly efficient.

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?

For a simple tool with one parameter and no output schema, the description covers the essential aspects: purpose, parameter hint, and inline image return. It could be more complete by noting the screenshot is static for the current day, but it's adequate for agent invocation.

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 coverage is 100% for the single parameter, so baseline is 3. The description adds value by listing example categories and referencing 'gta-map-categories' for valid values, but does not explain the format or meaning of the category slug beyond what the schema already provides.

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 specifies the action (capture screenshot), resource (GTA Online map), and scope (for a category showing today's marker positions). It distinguishes from siblings like gta-map-categories and gta-render-map by focusing on a visual screenshot with current data.

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 lists example categories but does not explicitly state when to use this tool over alternatives like gta-map-locations (textual data) or gta-render-map (possibly raw rendering). No when-not or alternative guidance is provided.

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