List Folders

list_folders

Read-onlyIdempotent

Discover all folder paths that contain documents, including root as an empty string, to filter search or list_documents by valid folder names.

Instructions

List all folder paths that contain documents.

Call this to discover valid folder names before filtering 'search' or 'list_documents' by folder. The root folder (top-level documents) is represented as an empty string "".

A4.5/5.0

Behavior4/5

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

Annotations already include readOnlyHint=true, idempotentHint=true, and destructiveHint=falseainer. The description adds useful behavioral detail by clarifying that root-level documents correspond to an empty string path. It does not contradict the annotations, though it leaves the wait_for_pending_writes behavior to the schema and parameter description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short, front-loaded, and has no filler. Both sentences contribute essential information: what the tool returns and the important root-folder convention.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple, read-only listing tool with one optional parameter, an output schema, and clear annotations, the description fully covers what an agent needs to select and invoke it correctly. The root-path clarification adds important context that is not otherwise obvious.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single optional parameter, and the schema itself explains its semantics, default, and timeout behavior. The tool description does not need to add anything further about parameters; baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific operation ('List all folder paths that contain documents') and clearly identifies the resource. It also distinguishes itself from list_documents and search by emphasizing folder paths rather than content or documents.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says to call this tool to discover valid folder names before filtering 'search' or 'list_documents' by folder. This gives clear, actionable guidance on when to use it and for what purpose.

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