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

Annotations already declare readOnlyHint=true, and 'Free, read-only' largely restates that. The description does add some non-schema behavior: that the returned ids feed lavela.destroy_resource, that destroy_resource is an advanced tool requiring a reconnect, and the meaning of the usedBy:'hosted_app' marker. That is useful but leans more on ecosystem context than on this tool's own operational traits (pagination, auth, result 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?

It is information-dense and opens with what is listed, but the sentence is heavily parenthetical and backticked, packing markers, a sibling-tool aside, and a reconnect URL into one tangled clause. It is neither bloated nor cleanly front-loaded.

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 an output schema present, return values need no explanation, and for a read-only one-parameter list tool the description covers resource types, the destroy_resource id linkage, and use cases. It is essentially complete; only the projectId format is left unstated.

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 0%, so the description must carry the single projectId parameter, which it only implies via 'A project's ...'. It never states the expected uuid format or that projectId is required, leaving meaning to inference from the schema.

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 enumerates exactly what is listed (managed databases, caches, storage, error tracking under type:'managed', and volumes under type:'volume'), which is more informative than the terse title. It does not name sibling list tools like list_projects, but the enumerated resource types let an agent distinguish it well enough.

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?

It gives concrete when-to-use cues: 'Call it before re-creating a database after a timeout, and to clean up.' That is clear context for the invocation, though it states no exclusions or rival tools to prefer instead.

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