get_validation_rules

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

No annotations are provided and the description gives no insight into behavior beyond the verb 'get'. It doesn't clarify whether rules are static data, computed, require auth, or what format they take. For a read operation with no annotation coverage, the description carries the full burden but adds essentially nothing beyond 'get rules'.

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 a single concise sentence with zero waste. However, it is under-specified rather than efficiently concise - one short sentence that adds little information beyond the tool name itself.

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 100% schema description coverage for the single parameter and no output schema, the description doesn't need to explain parameters or return values. However, the tool retrieves validation rules - a potentially nuanced concept - and the description doesn't explain what these rules look like, how they're structured, or how they relate to the entity/operation. The sibling tools (get_workflow, get_table_schema, get_field) suggest a documentation/exploration toolkit, but the description doesn't distinguish or elaborate.

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 the description adds no parameter info beyond what the schema already provides. The schema's entity description is quite detailed with examples. The baseline 3 is appropriate since the schema already handles the parameter well.

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 'Get validation rules for an entity or operation' - a clear verb+resource pattern. The 'or operation' phrasing adds helpful scope clarification. However, it doesn't distinguish from siblings beyond the 'rules' concept; 'get_table_schema', 'get_workflow', and 'get_api_endpoint' could all plausibly deliver validation-adjacent information.

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 names the two valid entity types ('entity or operation') but gives no guidance on when to use this tool versus alternatives like get_workflow or get_transitions, nor any exclusions or prerequisites. An agent must guess when validation rules are relevant versus other metadata lookups.

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