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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds 'privacy-filtered project metadata,' which is useful behavioral context, but it does not describe the return shape, pagination, or metadata fields, so it only partially supplements the annotations.

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 concise sentence with no filler, and it front-loads the read operation. It loses a point because 'Read hosted list linked projects' is grammatically awkward and less clear than a phrase like 'List linked projects' or 'Read the hosted list of linked projects.'

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-parameter, read-only tool, the essential pieces are present: the operation, the resource, privacy filtering, and annotations covering safety. However, the ambiguous 'hosted list linked projects' and the lack of an output schema leave some uncertainty about exactly what is returned, so the description is adequate but not complete.

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?

This tool has zero parameters, so there are no parameter semantics to clarify; the baseline for a zero-parameter tool is 4. Schema coverage is effectively complete because the input schema is empty.

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 'Read' plus 'linked projects' to identify the operation and resource, and the resource name distinguishes it from sibling list_* tools. However, the phrase 'hosted list linked projects' is grammatically awkward and does not say what projects are linked to, so it is not fully precise.

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 given about when to use this tool versus any of the many sibling list/get tools. The description does not name alternatives, exclusions, or contextual conditions, leaving the agent to infer usage from the tool name alone.

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