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

With no annotations, the description carries the full burden and only hints that a list is returned ('short list of their apps'). It says nothing about read-only nature, permissions, how the list is scoped or paginated, or what the response contains beyond 'identity'.

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 compact sentence with the key content front-loaded. It is efficient, though efficiency here shades into under-specification rather than disciplined brevity.

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?

There is no output schema and no annotations, and the description does not compensate: it leaves the limit parameter, id expectations, and return shape unexplained. For a 2-parameter lookup tool with zero structured support, more detail was needed.

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 0%, so publisherId and limit are undocumented in structured fields. The phrase 'short list of their apps' weakly implies the limit parameter caps that list, but neither the id format (maxLength 120) nor the limit range (1-200) is clarified in the description.

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 names the resource (publisher) and what it returns (identity plus a short list of apps), which distinguishes it from siblings like get_app and get_app_market. However, it is a noun phrase with no verb, so it never explicitly states that this is a lookup/retrieval operation for a given publisherId.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as get_app or find_apps. The agent must infer that this is the publisher-level counterpart to get_app from the name alone.

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