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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds a genuinely useful constraint about what is NOT returned ('without pricing or upgrade links') and mentions 'current export quality and watermark constraints', but omits auth/permission needs and the meaning of the nullable workspaceId default.

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?

It is front-loaded with the verb and resource, and the long field enumeration is purposeful rather than filler. The second sentence about export quality/watermark constraints is well-placed, though the field list is somewhat verbose.

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 single-parameter read-only tool with an output schema and full annotation coverage, the return shape is adequately covered by the output schema, so the description need not restate fields. The remaining gap is the unexplained nullable workspaceId and absent usage routing, which is minor here.

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?

There is a single parameter with 0% schema description coverage, so the description must carry the load. It implies scope via 'the selected workspace's', but never explains workspaceId itself nor what happens when it is null (the schema default), leaving the nullable behavior undocumented.

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 ('Read') and resource ('the selected workspace's business context') and enumerates the exact fields returned, so the agent knows precisely what it fetches. It contrasts implicitly with the save sibling via 'Read', but no sibling is named explicitly, which keeps it short of a 5.

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 description gives no when-to-use guidance, no exclusion criteria, and does not mention the alternative workspace_context_save or workspace_brand_scan. An agent must infer that this is the read counterpart to save purely from the verb.

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