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

No annotations provided, so description carries full burden. Mentions 'draft' context (valuable), implying changes affect unpublished state. However, fails to disclose that updates are partial (only provided fields change), lacks warning about validation, permissions, or whether changes require subsequent submit_app invocation.

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?

Single efficient sentence with front-loaded action verb. Parenthetical list provides quick field reference without verbosity. No redundant or wasted text.

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 13-parameter mutation tool with no annotations or output schema, description covers basic purpose but leaves critical gaps: partial update semantics, return value structure, prerequisite steps (e.g., query_app_info), and relationship to submit_app for finalization.

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 has 69% coverage (cs_email, cs_phone, cs_url, app_name lack descriptions). Description compensates by mapping business concepts ('support contacts') to parameter groups, adding clarity. Baseline 3 for decent schema coverage, elevated for mapping undocumented params.

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 'Update' and resource 'app metadata in AppGallery Connect draft'. Parenthetical field list (name, description, category, etc.) distinguishes from siblings like update_app_file_info or update_language_info. However, doesn't explicitly clarify distinction from update_language_info which could confuse users.

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 explicit when-to-use guidance relative to siblings (e.g., vs update_language_info for localization). Critically misses explaining that 0 parameters are required, implying partial/PATCH updates—users might incorrectly assume they must provide all fields.

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