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

With no annotations provided, the description carries the full behavioral burden, but it only discloses the owner-only permission requirement. It says nothing about whether the update is partial or full, whether omitted fields are preserved, or what the result contains.

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?

Two short, front-loaded sentences with no filler. The purpose comes first and the permission constraint second, which is efficient, though it is arguably too terse given the gaps.

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 mutation tool with no annotations and no output schema, the description is far too thin. It omits partial-vs-full update semantics, reversibility, return value, and error behavior, leaving significant gaps an agent needs filled.

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 each of the four parameters (icon, color, title, workspaceId) is already documented in the schema. The description adds nothing about parameter meaning, so the baseline of 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 clear verb+resource (update a workspace), which is unambiguous on its own. However it does not differentiate from the many sibling update_* tools or explain what fields are updatable, leaving the reader to infer from the name alone.

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?

The only guidance is the authorization constraint ('Only the workspace owner can update'). There is no when-to-use vs alternatives, no mention of get_workspace/list_workspaces for reading, and no context on when updating is appropriate.

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