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

With no annotations, the description carries the full behavioral burden. It notes the output is a JSON tree but says nothing about recursion depth, hidden/ignored file handling, permission requirements, or pagination, which matter for a file-listing 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 front-loaded sentence with the verb first and the return format trailing. No wasted words, though the extreme terseness leaves the behavioral gaps noted elsewhere.

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?

An output schema exists, so return values need not be explained, and there is only one obvious parameter. However, the description omits behavioral context (recursion, filtering, permissions) that an agent would want when choosing among the many list_* and file-access siblings.

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?

One parameter (project_id) at 0% schema description coverage, so the description must compensate. It implies project scoping, but adds no meaning beyond the self-evident parameter name; baseline 3 is appropriate given the single, obvious parameter.

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), resource (project file structure), and output shape (JSON tree), which is enough for an agent to know what it returns. It is not explicitly differentiated from siblings like list_versions or list_projects, but the scope is clear.

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 on when to use this versus read_file, list_versions, or list_projects, and no exclusions or prerequisites. The agent must infer usage from the name alone.

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