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

Annotations are absent. Description indicates upsert behavior ('Add or update'), which is useful behavioral context. However, lacks critical safety disclosure for a mutation tool: does not specify whether omitted fields preserve existing values or are cleared, does not mention required permissions, or idempotency.

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?

Extremely concise single sentence of 11 words. Front-loaded with the action and resource. No redundant or filler text; every word conveys specific information about the operation or affected 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?

Mutation tool with 6 parameters, no annotations, and no output schema requires substantial operational context. Description is too thin: omits 'brief_desc' parameter entirely, does not explain partial update semantics (only 'lang' is required), and provides no indication of return values or error conditions.

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 coverage is 50%. Description compensates by mapping semantic meanings to three parameters lacking schema descriptions: 'name'→app_name, 'description'→app_desc, 'release notes'→new_features. Fails to mention 'brief_desc' at all, leaving one content field undocumented.

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?

Clear verb ('Add or update') + resource ('localized store listing') + scope ('for a language'). Mentions specific content fields (name, description, release notes) that map to parameters. Does not explicitly distinguish from sibling 'update_app_info', but 'localized' provides implicit differentiation.

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?

No guidance on when to use versus 'update_app_info' or other siblings. Does not mention prerequisites like requiring 'app_id' or environment variable fallback behavior documented in the schema. No warning about partial updates or required fields.

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