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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds content-structure context (namespaces under `tools`, connected-app status), but the return shape is also covered by the output schema, so incremental value is modest.

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?

Two tight sentences with the purpose front-loaded and the follow-up action last. The second sentence is a pointer to a sibling rather than direct tool behavior, but it is short and earns its place by enabling the next step.

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?

With zero parameters, rich annotations, and an output schema covering return values, the definition only needs to frame intent and next steps, which it does. It could add one clause on when this call is unnecessary, but nothing required for correct invocation is missing.

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 nothing for the description to disambiguate; baseline 4 applies. The description correctly conveys that discovery is unfiltered and namespace-scoped rather than parameterized.

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 specific verb (list) and resource (what a script can call / integrations) and enumerates the concrete contents: crevioApi, platform namespaces under `tools`, and connected apps with status. It explicitly distinguishes itself from the sibling list_integration_tools, which it positions as the follow-up for drilling into a namespace.

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?

The description gives clear sequencing guidance: call this first to discover namespaces, then 'list a namespace's functions with list_integration_tools.' It names the alternative tool and the condition that selects it, but does not state explicit exclusions or when this tool is the wrong choice.

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