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

Annotations already carry the safety profile (readOnlyHint=true, idempotentHint=true, destructiveHint=false, openWorldHint=false), so the bar is lower. The description adds useful content-scope context by listing what the response contains (files, published state, URL, active jobs), which is beyond the annotations. No contradictions, but it adds nothing about reach, pagination, size limits, or response shape.

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?

A single front-loaded sentence with zero filler. The purpose leads immediately, and the component list (files, published state, URL, active jobs) earns every word by demarcating the tool's scope. Nothing could be trimmed without losing meaning.

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 simple one-parameter, read-only tool with rich annotations and no output schema, the description is reasonably complete: it names the sole required parameter's purpose via the schema and lists the four return components. It could note the aggregate nature versus get_app_detail or describe the response structure, but these are minor against the tool's low complexity.

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% — the single parameter app_id is documented as 'The app ID' in the schema. The description adds no additional parameter meaning (format, origin, or examples), so it rests on the schema's documentation, matching the baseline for full coverage.

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 ('Get app overview') and enumerates the returned components (files, published state, URL, active jobs), which clearly conveys a summary/aggregate tool. It distinguishes itself from the focused siblings like get_app_files and get_job_status by signaling it is an aggregate overview, though it does not explicitly name any alternative.

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?

There is no guidance on when to use this overview tool versus the many overlapping siblings (get_app_detail, get_app_files, get_app_links, get_job_status, get_pages). The word 'overview' only implies a quick-summary use case; no exclusions or selection criteria are given, leaving the agent to infer the appropriate choice.

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