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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is fully covered structurally. The description adds only the ownership scoping ("the user's"), and says nothing about result volume, ordering, or pagination behavior — which is the main open question for a list tool.

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 short sentence with zero filler, front-loading the verb and resource. It is efficient, though so terse that efficiency shades into under-specification rather than a deliberate structure.

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 no-arg read tool with annotations and no output schema, the description is minimally adequate. It leaves open what the listing contains (counts, ordering, whether all projects or a truncated set), which is exactly the context an agent would want before choosing between this and get_project.

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 zero parameters and the schema is empty, so there is nothing for the description to compensate for. Baseline 4 applies; no parameter meaning is missing because no parameters exist.

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 (list) and resource (projects) with the scope qualifier "the user's," which distinguishes it from project-scoped tools like get_project or update_project. It stops short of explicitly naming any sibling (e.g., get_project for a single project), so the differentiation is inferable rather than stated.

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 gives no when-to-use condition, no mention of when to prefer get_project for a single project, and no prerequisites. An agent must infer the usage entirely from the verb and the surrounding tool list.

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