create_translation_key_bulk

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

The description adds a meaningful behavioral detail beyond the annotations: it doesn't throw an error when a translation key already exists and instead returns a list of failures. This supplements the readOnlyHint=false and idempotentHint=false annotations with useful real-world behavior.

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 concise, with the primary purpose in the first sentence and bullets for constraints. It is front-loaded and easy to scan, though it slightly duplicates schema information such as the max-100 limit and optional fields.

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 a single required parameter with a fully described schema, the description covers the essential usage constraints and duplicate-key behavior. The lack of an output schema is partially mitigated by the note that failures are returned, but the exact response structure is still unspecified.

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%, and the description largely restates what the schema already provides: each object must include 'key' and may include optional fields. It adds no new parameter-level meaning beyond the schema, so the baseline score applies.

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 a specific action, resource, and scope: 'create multiple translation keys in your SimpleLocalize project in bulk.' The word 'bulk' clearly distinguishes this from the sibling create_translation_key, and the array-based input reinforces the plural nature.

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 makes the intended usage clear by emphasizing bulk creation and capping the request at 100 objects. However, it does not explicitly name an alternative for single-key creation or state when this tool would be inappropriate, so it stops short of full when/when-not guidance.

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