list_namelist_options

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

No annotations are provided, and the description lacks behavioral details. It does not disclose that the tool is read-only, any authentication requirements, rate limits, or what happens when no group is provided (returns all options). The description only states the action.

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 very concise at one sentence, front-loaded with the action. It contains no unnecessary words. However, it could benefit from a slightly fuller explanation without becoming 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?

Given the tool's low complexity (single optional parameter, output schema exists), the description is adequate but minimal. It does not mention that the output is a list (though implied by 'list') or how results are ordered. The existence of an output schema partially compensates, but a fuller description would enhance completeness.

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%, and the description only implicitly mentions the 'group' parameter via 'filtered to one group'. It does not explain what a group is or provide any additional semantics beyond the schema's field name and type.

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 clearly states the action (list namelist options) and mentions optional filtering by group. It distinguishes from sibling tools like 'list_namelist_groups' (which lists groups) and 'get_namelist_option' (single option), though it could be more explicit about differences from 'search_namelist_options'.

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?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or exclusions (e.g., when to use search_namelist_options instead). The optional group filter is implied but not elaborated.

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