Create Value List

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

Annotations already disclose that this is a non-read-only, non-destructive, non-idempotent, closed-world mutation, so the bar is lower. The description adds useful entry semantics and numeric range syntax, but does not address uniqueness constraints, permissions, or what happens on duplicate names.

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 three compact sentences, front-loaded with the action and resource. The definition and range syntax each earn their place with no filler.

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?

An output schema exists and parameter descriptions are complete, so the description needn't explain return values. It covers the core concept and entry syntax but omits sibling routing, which is a minor gap for a create tool with clear schema support.

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 100%, so baseline is 3. The description goes beyond the schema by explaining that entries are values or ranges and by documenting the 'v>=630' range syntax, which is meaningful for the 'entries' 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 gives a clear verb and resource ('Create a value list') and explains what a value list is. It does not explicitly distinguish this tool from close siblings such as create_lookup_table or update_value_list_entries, so it falls short of the top score.

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 mentions domain context (segmentation tree variables and rule conditions) but gives no explicit guidance on when to use this tool versus alternatives like update_value_list_entries or create_lookup_table. No exclusions or prerequisites are stated.

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