sentinel_metadata

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

No annotations are given, and the description does not disclose behavioral traits such as idempotency, authentication requirements, rate limits, or potential side effects. The agent is left to assume it is a safe read operation, but this is not explicitly stated.

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 clear sentence with no unnecessary words. It could be improved by adding structure (e.g., bullet points) but remains effective and concise.

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 description is too brief for a tool with no output schema. It does not indicate what metadata fields are returned, the response format, or any constraints. For a metadata retrieval tool, more detail is needed to allow the agent to judge if it meets the need.

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 100% (product_id is documented as a UUID). The description does not add any new parameter information beyond what the schema provides, so the baseline score of 3 is appropriate.

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 'Get', the resource 'detailed metadata for a Sentinel-2 product', and the identifier 'by ID'. This distinguishes it from sibling tools like sentinel_bands, sentinel_download_url, and sentinel_latest, which have different purposes.

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 guidance is provided on when to use this tool versus alternatives. For example, it does not explain when to prefer this over sentinel_bands or sentinel_search, nor does it mention prerequisites or whether it is for single or batch queries.

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