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

With no annotations provided, the description carries full burden and does well by disclosing key behavioral traits: it handles up to 100 items, doesn't error on duplicates (returns failures list instead), and operates in bulk. It misses details like rate limits, idempotency, or response format specifics, but covers essential mutation behavior adequately.

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 efficiently structured with a clear opening sentence followed by bullet points that add necessary details without redundancy. Every sentence earns its place by clarifying constraints and behavior, making it front-loaded and zero-waste.

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 mutation tool with no annotations and no output schema, the description is moderately complete: it covers the bulk nature, duplicate handling, and basic input structure. However, it lacks details on authentication, error responses, or what the 'failures list' contains, leaving gaps for an agent to invoke it correctly in all contexts.

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 schema fully documents the single parameter 'translationKeys' and its nested properties. The description adds minimal value beyond the schema, only reiterating the array structure and max limit. Baseline 3 is appropriate as the schema does the heavy lifting.

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 specific action ('create multiple translation keys in bulk'), identifies the resource ('SimpleLocalize project'), and distinguishes from siblings like 'create_translation_key' (implied singular) and 'delete_translation_keys_bulk'. It explicitly mentions bulk creation versus individual operations.

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 provides clear context for when to use this tool (bulk creation of up to 100 keys) and implicitly contrasts with non-bulk alternatives. However, it lacks explicit guidance on when NOT to use it (e.g., vs. 'update_translation_key' for existing keys) or prerequisites like authentication needs.

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