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

No annotations are provided, so the description carries the full behavioral burden. It does disclose what is surfaced (identity plus granted scopes), but says nothing about whether credentials are required, whether it can fail or return empty, or how scopes are formatted. For a zero-risk read tool this is adequate but thin.

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 twelve-word sentence with zero waste, front-loaded on the verb and the resource inspected. Nothing to trim and nothing buried.

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?

With no output schema, the description usefully names the two return concepts (identity, granted scopes), which is the main thing an agent needs. It stops short of describing failure modes or scope encoding, but for a parameterless read tool the coverage is solid.

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 tool takes no parameters, so the baseline is 4; there is nothing for the description to disambiguate. The description correctly adds no parameter noise.

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?

States a specific verb ('Inspect') and a specific resource ('current authenticated Codebase identity and granted scopes'), so an agent knows exactly what comes back. No sibling tool touches identity or scopes, so explicit differentiation isn't needed, though it isn't called out either.

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 phrase 'current authenticated' implicitly signals the use case (verifying which identity and scopes are active, e.g. before a deploy or publish), but there is no explicit when-to-use, prerequisite, or named alternative. Usage is implied rather than stated.

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