panelica_file_manager_get_v1_files_accessible_directories

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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds only the required files:read scope and labels the operation read-only, which is useful but adds little behavioral context beyond what the name and annotations convey.

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 four short lines with no filler; the endpoint, category, required scope, and read-only marker each contribute useful metadata. The core action is front-loaded and the whole definition is easy to scan.

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 single-parameter GET with rich annotations this is near-adequate, but there is no output schema and the description does not say what an 'accessible directory' entry contains or how user_id affects the result. An agent can call it but cannot predict the response shape.

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?

Schema description coverage is 100%, and the sole parameter user_id is already documented as 'Target user ID'. The description itself adds no parameter-level meaning, so the schema carries the burden and the baseline 3 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?

The description states a clear verb and resource, 'Get accessible directories' with the HTTP path, and the 'directories' resource distinguishes it from the many file-listing siblings such as get_v1_files. However, it does not explain what 'accessible' means or explicitly contrast it with sibling file manager tools, so it falls just short of full distinctness.

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?

There is no guidance on when to use this tool rather than alternative file manager listing or permission tools. The description gives endpoint, category, and scope metadata but no context, exclusions, or alternative routing, so an agent must infer the intended use 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.
