check_coverage

Check satellite image availability for a specific region and time period using Copernicus Sentinel data. Analyze temporal coverage to plan Earth observation projects.

Instructions

Check satellite image coverage for a region over time

C2.8/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what the tool does but doesn't describe how it behaves—such as whether it's a read-only operation, what the output looks like, any rate limits, or authentication requirements. This is inadequate for a tool with 6 parameters and no annotation coverage.

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

Conciseness5/5

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

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded, making it easy to understand at a glance.

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

Completeness3/5

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

Given the tool's complexity (6 parameters, no annotations) and the presence of an output schema, the description is incomplete. It doesn't explain parameter semantics or behavioral traits, though the output schema might cover return values. This leaves significant gaps for the agent to understand how to use the tool effectively.

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

Parameters1/5

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

The description adds no meaning beyond the input schema, which has 0% description coverage. With 6 parameters (3 required) and no explanation in the description of what 'geometry', 'mission', or 'group_by' mean, the agent lacks crucial context for proper tool invocation.

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

Purpose4/5

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

The description clearly states the tool's purpose as checking satellite image coverage for a region over time, specifying the resource (satellite images) and action (check coverage). However, it doesn't differentiate from sibling tools like 'check_download_availability' or 'search_copernicus_images', which might have overlapping functionality.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. With siblings like 'check_download_availability' and 'search_copernicus_images', there's no indication of when this coverage check is preferred, what prerequisites exist, or when not to use it.

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