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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the agent knows this is a safe read operation. The description confirms the read-only nature but adds little beyond that; it does not disclose the return shape or edge-case behavior, which would have added value given the absence of an output schema.

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?

A single, front-loaded sentence that states the essential behavior with no filler. It is appropriately concise for a simple read operation, though it could have earned a 5 by also including a brief note on expected return or usage context.

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 two-required-parameter read, the description, schema, and annotations together provide enough context to understand what the tool does. The main gap is the lack of any description of the return value, but the word 'whether' strongly implies a boolean-style result, which partially mitigates this.

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%: owner and taker are both described as addresses, and the params field is documented as optional raw JSON. The description adds semantic context by framing these parameters as a stake-owner/taker relationship, but it does not go beyond what the schema already conveys.

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 uses a specific verb ('Read') and a precise resource ('whether a stake owner authorizes a taker'), making the tool's function immediately clear. It does not explicitly name a sibling to differentiate from, but the relationship being queried is distinct enough among the peer_stake_* tools.

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 implies this tool is for checking authorization between a stake owner and a taker, but it gives no explicit when-to-use/when-not-to-use guidance or alternatives. The context is understandable from the wording, but the tool description does not proactively route the agent away from other read tools.

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