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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the useful scoping fact that results are limited to the authenticated user, but says nothing about result shape, pagination, ordering, or whether it is a combined feed across the two resource types.

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 sentence that front-loads the verb and the two returned resource types with zero filler. Nothing is padded or redundant.

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 no parameters, no output schema, and no nested objects, the definition is simple enough that the description is nearly adequate. However, with no output schema the description should at least characterize the return (two collections? interleaved list? paginated?), and it does not.

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?

The tool takes zero parameters, so the baseline is 4. The schema is empty and nothing in the description is needed to explain inputs; the only constraint worth noting, the authenticated-user scope, is implicit in the session rather than a parameter.

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?

The description states a specific verb ("List") and two concrete resources ("tasks and merchant offers") scoped to the authenticated user, which is more specific than the bare tool name my_workspace. It stops short of distinguishing itself from siblings like search_tasks, search_offers, or list_my_actors, so an agent must infer the boundary.

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?

There is no when-to-use guidance and no named alternative. The phrase "owned by the authenticated user" implies a scoping rule, but the description never says whether to prefer this over search_tasks/search_offers for a narrower query or get_task for a single item.

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