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

The annotations already declare destructiveHint=true and readOnlyHint=false, so the write/destructive nature is known. The description adds the owner-permission requirement, which is genuine context beyond the annotations, but it does not clarify why a rename carries a destructive hint or what side effects (links, uniqueness) a rename may have.

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 short, front-loaded sentence with no filler. The 'Update Workspace - ' prefix restates the title and is the only wasted token.

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?

With a complete schema, an output schema, and annotations, most needs are covered. The description still omits what a rename affects externally and how owner-only failure surfaces, leaving the agent to infer consequences of a destructive-hinted operation.

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 parameters are fully documented structurally (id, name with min length, workspace_id fallback). The description only echoes the 'name' concept and adds nothing about id vs workspace_id resolution, 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 and resource ('Update Workspace') and narrows the scope to a single field ('workspace name'), which distinguishes it from create_workspace and get_all_workspaces. The leading phrase duplicates the title, so it stops short of full sibling differentiation.

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?

'(owner only)' gives a real prerequisite for calling it, which is more than most siblings offer. However, there is no explicit guidance on when to use this versus select_workspace or create_workspace, and no note on what happens if a non-owner calls it.

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