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

Annotations declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false. The description adds nothing beyond these: it does not explain partial vs. full update semantics, what happens to omitted fields, whether workspace type can be changed, or the non-idempotent behavior. For a 21-parameter mutation tool with zero annotation-derived detail, this is a significant gap.

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 wasted clauses beyond the redundant 'that has previously been created'. It is appropriately sized only in the sense that it is short, but the brevity reflects under-specification rather than density.

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 tool with 21 parameters, nested provider config objects, an enum type field, and a non-idempotent mutation profile, the description is far too thin. An output schema exists so return values need not be explained, but the behavioral and usage gaps remain unaddressed.

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%, so the schema fully documents all 21 parameters including nested provider objects and conditional requirements. The description adds no param-level meaning beyond the schema, so 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?

States a specific verb+resource: 'update video workspace'. However, it does not distinguish itself from siblings such as create_workspace, delete_workspace, get_workspace, or live_workspace_update, and the phrase 'that has previously been created' is filler that adds no differentiating information.

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 tool versus alternatives like live_workspace_update or update_asset, no prerequisites (e.g., workspace must already exist, permissions needed), and no mention of which fields can be changed. The only context is the implied 'workspace exists' condition.

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