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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only that returned data is 'current' choices and ticks, which is modest added context; it says nothing about scoping, permissions, or result shape.

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 waste. It is appropriately sized, though the terseness leaves the gaps noted in other dimensions unaddressed.

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 read tool with three undocumented parameters, no output schema, and no parameter meaning anywhere, the description is thin. An agent can guess the intent but lacks enough to call it confidently, especially the role of the optional token.

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 0%, so all three parameters (token, spaceId, activityId) are undocumented in both schema and description. The description doesn't clarify what spaceId vs activityId identify or what the optional token is for, so it fails to compensate for the gap.

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 (an activity's current choices and ticks), which distinguishes it from siblings like activities_tick_choice or activities_offer_choice, which mutate. It doesn't explicitly name those siblings, but the read framing is clear.

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 word 'Read' implies this is the retrieval counterpart to the tick/offer/lock mutations, but the description never states when to use this versus alternatives or any prerequisites. Usage is left to be inferred from the sibling names.

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