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

Annotations already declare this read-only, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds a genuine scope constraint (only folders you own or belong to), but says nothing about result size, pagination, or ordering. Adequate with gaps rather than rich.

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 fragment with the scoping constraint front-loaded and no wasted words. It is arguably too terse, since it reads as a noun phrase rather than a statement of what the call does, but nothing is padded.

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 tool with annotations covering safety, the main remaining gap is the return shape: there is no output schema, yet the description never says what a folder entry contains (e.g. name/ID), which an agent needs to chain into organize_project. The organize_project linkage partially compensates.

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, so there is nothing for the description to disambiguate; baseline for a no-parameter tool 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?

Names the resource (folders) and the scope (those you own or belong to), which separates it from list_projects and list_parts. The verb 'list' is only carried by the tool name and title, not the description body, so it is clear but not fully self-contained.

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?

Mentioning 'where organize_project can file a project' implies the follow-up call and why an agent would fetch folders, but it never states when to use this versus the other list_* tools or any prerequisite. Usage is inferable rather than explicit.

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