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

No annotations are provided, so the description carries the burden of behavioral disclosure. The words 'recommend' and 'decide' imply an advisory, non-mutating output, which is useful, but there is no statement about permissions, determinism, cost, or side effects for an agent that must reason about safety.

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 tight sentences with the core purpose front-loaded and no redundant restatement of the name or title. It is efficiently sized for a one-parameter tool, though the second sentence could be sharper.

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 single-parameter tool this is nearly adequate, but there is no output schema and the description never states what the recommendation actually returns (a ranked provider list? a config?). It only implies a set of providers to include, leaving the return shape to inference.

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?

The single parameter is fully documented in the schema (100% coverage, with an example such as BTC/ETH), so the schema does the heavy lifting. The description adds the notion that the recommendation is derived from active feeds but contributes no additional per-parameter syntax or constraint detail.

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?

Names a specific verb (recommend) and resource (oracle provider setup for an asset) and adds the basis for the recommendation (active feeds), which distinguishes it from the read-only siblings like get_oracle_health or compare_oracle_deviation. It stops short of explicitly contrasting itself with any of the many neighboring oracle tools, so it is clear but not fully differentiated.

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 second sentence gives a concrete use context: deciding which providers to include in price feeds or risk analysis. That is a real when-to-use signal, but it offers no exclusions and never names an alternative tool or the conditions under which a different sibling should be preferred.

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