list_apps

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

The description clearly frames this as a read-only enumeration and discloses that results contain fake credentials under the MockPost identity, which is useful because no annotations are present. It does not mention pagination or ordering, but the output schema covers the return 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 sentence with a front-loaded verb and object, plus one valuable parenthetical clarifying the identity context. No filler or redundancy.

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 zero-parameter list tool with an output schema, the description is largely complete and tells the agent exactly what it will fetch. It could add one sentence about when listing apps is useful relative to the register/set/delete siblings, but that gap is already captured in the usage_guidelines dimension.

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?

There are zero parameters, so the description has no need to define parameter semantics. The 100% schema coverage and empty properties confirm no inputs are required.

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?

States a concrete operation—listing registered apps—and clarifies the data returned (fake credentials in MockPost identity). This differentiates it from registration/deletion/set siblings and from a generic app-listing tool.

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 or when-not-to-use guidance is provided, and no alternative sibling tools are mentioned. The agent must infer from the verb 'List' and sibling names that this is for enumeration rather than registration, modification, or deletion.

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