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

The description adds the bearer-token authorization requirement, a genuine behavioral constraint not present in the schema. However, with no annotations, it does not disclose whether the operation is read-only, how results are paginated, or what a typical response looks like.

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 short sentences with the action front-loaded and the authorization note immediately after. Every word earns its place; no redundant phrasing.

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 zero-parametr list tool the description is nearly adequate, covering purpose and auth. However, without an output schema or annotations, it leaves the agent uninformed about return shape, pagination, or how this relates to get_token, so complete guidance is missing.

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, so the empty schema is trivially complete. The description need not add parameter-level detail, and the baseline for zero-parameter tools applies.

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?

Clearly identifies a list/browse operation over the token resource on BaseAlpha, reinforced by the tool name. It stops short of a 5 because it does not explicitly say it returns all tokens or how it differs from get_token.

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?

Provides no guidance on when to use list_tokens versus get_token, get_signals, or other siblings. The only practical context is the authorization requirement.

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