Workspace Update File

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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds one behavioral fact beyond that – parentId triggers a move – but says nothing about required permissions, whether unspecified properties are preserved, or what a partial update does.

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 no filler. It is efficient, though arguably too terse for a tool whose body schema is entirely opaque.

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 no explanation, but for a mutation tool with an opaque free-form body the definition leaves too much unstated: accepted fields beyond the two named, permission requirements, and behavior on unmentioned properties.

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 coverage is 0% and body is a free-form object (additionalProperties: true), so the schema documents nothing. The description names only name and parentId and leaves inode_id and all other accepted body properties unexplained, compensating only partially for a total schema gap.

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+resource ("Update file properties") and enumerates two updatable fields, so an agent can tell it apart from workspace_delete_file and workspace_list_files. It doesn't explicitly name an alternative sibling, but the purpose itself is unambiguous.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as workspace_delete_file or workspace_create_folder. The parenthetical about parentId implies a move operation but never states that this is the tool to use for moving.

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