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

No annotations are provided, so the description carries the full burden. It mentions 'update' (implying mutation) and 'max 100' items, but doesn't disclose critical behavioral traits: whether this requires specific permissions, if updates are reversible, what happens on partial failures, or rate limits. For a bulk mutation tool with zero annotation coverage, this is a significant gap.

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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by bullet points for key details. No wasted sentences, though the bullet points slightly repeat schema information. Overall efficient.

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 the tool's complexity (bulk mutation with no annotations and no output schema), the description is moderately complete. It covers the basic operation and parameter structure, but lacks behavioral context (e.g., error handling, permissions) and output details. For a mutation tool, this leaves gaps that could hinder agent usage.

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 already documents all parameters thoroughly. The description adds minimal value beyond the schema: it lists required and optional fields in the translation objects, but doesn't provide additional semantics like format examples or constraints beyond what's in the schema. Baseline 3 is appropriate when 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 tool's purpose: 'update multiple translations in bulk in your SimpleLocalize project.' It specifies the verb ('update'), resource ('translations'), and scope ('bulk'). However, it doesn't explicitly distinguish this from sibling tools like 'update_translation_key' (singular) or 'create_translation_key_bulk' (creation vs. update).

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 implied usage guidance: 'Use this for efficient mass updates.' This suggests it's for batch operations, but it doesn't explicitly state when to use this tool versus alternatives like 'update_translation_key' (for single updates) or 'create_translation_key_bulk' (for creation). No exclusions or prerequisites are mentioned.

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