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

Annotations already declare readOnlyHint=true, so the safe-read nature is covered. The description adds behavioral context by noting the list's members are 'resolved' to current values, which implies dynamic lookup rather than raw stored data, and it discloses pricing/plan inclusion. No contradiction with annotations.

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?

The description is compact and front-loaded with the core action, resource, and output semantics in one sentence. The pricing note is additional but brief and useful for cost-aware selection; it does not clutter the primary purpose.

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?

Given this is a simple read-only single-list retrieval with one required parameter and no output schema, the description covers ownership, the main return content, dynamic resolution, and pricing. It omits response envelope and potential pagination details, but those are not critical for a basic get-list call.

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 coverage is 50%: the context parameter is well described in the schema, but id has no schema description. The description adds some meaning by implying id identifies a list the caller owns and that the response will enrich members, but it does not explain id format, source, or expected values.

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: 'Get a list you own,' and specifies the returned member data (current name, band, score). The ownership qualifier and 'resolved' detail distinguish it from siblings like list_lists, which would enumerate lists rather than retrieve one enriched list.

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 implies this tool is for retrieving a single list the caller owns, with resolved member details dropped. However, it does not explicitly state when to prefer it over alternatives such as list_lists, create_list, or add_to_list, nor does it mention any conditions or exclusions.

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