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

The description provides some behavioral context, such as 'block-latency' suggesting real-time updates and 'decentralized pricing' hinting at the data source. However, it does not disclose whether the tool is read-only, caching behavior, or any side effects. Since no annotations are present, the description bears full responsibility but only partially fulfills it.

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 of 13 words, front-loading the tool's purpose. Every word contributes meaning, with no redundant or unnecessary content.

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?

Despite low complexity (no parameters), the description does not specify what the output looks like. Since there is no output schema, the description should explain return values (e.g., a list of feeds, a summary). It only mentions features but not the shape or content of the response.

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?

There are no parameters (schema coverage 100%), so baseline is 4. The description adds meaning by explaining that the tool provides an overview of the FTSOv2 oracle, which is not evident from the empty schema alone.

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 identifies the tool as an overview of the FTSOv2 enshrined oracle, mentioning block-latency feeds, 1000 feeds, and decentralized pricing. It distinguishes from siblings like flr_price which likely provide specific feed prices. However, it could be more precise about what exactly the overview contains.

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 alternative tools. The description does not indicate any context where this overview is preferred over other oracle-related tools (e.g., flr_price for specific feeds).

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