update_translations_bulk

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the mutation is expected. The description adds that the operation is a bulk update with a 100-item constraint, but this is also present in the schema. It does not disclose edge behaviors like whether missing keys are created or how partial failures are handled.

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 brief, front-loaded with the core action, and organized into four scannable bullets. Each sentence adds functional information, with no fluff or redundancy.

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?

The description plus schema provides enough to invoke the tool for straightforward bulk updates. However, with no output schema, it does not clarify return format, error behavior, or whether this updates only existing keys versus upserts, which would be valuable for a mutation tool.

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 input schema already documents the 'translations' array and every field. The description adds a convenient summary of required vs. optional fields but no deeper meaning beyond what the schema provides.

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 verb and resource: 'update multiple translations in bulk in your SimpleLocalize project.' It clearly differentiates from sibling tools like update_translation (singular) and create_translation_key_bulk (creation) by emphasizing bulk updates.

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 last bullet, 'Use this for efficient mass updates,' provides a clear when-to-use context. It does not explicitly name alternatives or state exclusions, so it stops short of a 5.

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