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

With no annotations, the description carries the full burden, and it does disclose what comes back: status values (draft, pending, live, hidden, expired, sold, denied), views, interested buyers, and outstanding draft requirements. It says nothing about authentication requirements, result size, ordering, or pagination, which matters for a list tool that could return many rows.

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 that opens with the verb and scope before enumerating the payload fields; no filler or repetition. The long parenthetical status list is dense but each item adds discriminating information, so nothing is wasted.

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?

No output schema exists, so the description must convey return values, and it does so field by field. Gaps remain around ordering/pagination and how "what each draft still needs" is represented, but for a zero-parameter read tool it is largely sufficient to call correctly.

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?

The tool takes zero parameters, so there is no parameter semantics to clarify; the baseline of 4 applies. The description reasonably spends its space on return content instead of input.

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?

"List the founder's apps for sale" gives a specific verb and resource, and the ownership scope ("the founder's") implicitly separates it from the sibling search_apps_for_sale. It stops short of naming an alternative explicitly, but an agent can tell what this tool returns without opening a schema.

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?

Usage is only implied: "the founder's" signals this is the caller's own listings rather than a public search, which is the key distinction from search_apps_for_sale. There is no explicit when-to-use statement, no exclusion of the search sibling, and no note about authentication or ownership prerequisites.

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