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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, and the description's 'Read-only' merely restates that. The one genuinely additive fact is the cost model ('Free, 0 credits'), which annotations cannot express, but pagination/ordering behavior and result shape are left unstated.

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?

Three terse fragments, no filler, and the resource is front-loaded. Slightly telegraphic to the point of omitting useful detail, but nothing wasteful.

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?

The mention of URLs gives partial return-value context despite there being no output schema, and the cost note is helpful. However, for a list tool with an undocumented pagination parameter, the description leaves the agent guessing about the result shape and limit semantics.

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% and the single 'limit' parameter (1-50) is undocumented in both schema and description. 'Your most recent' hints at a recency ordering but never explains what limit controls or its default.

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+resource: listing the caller's most recent teardown reports, including their URLs. It implicitly distinguishes itself from the sibling 'teardown' (which presumably generates a report), though it never names that relationship explicitly.

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. The agent can infer you call this to retrieve reports after running a teardown, but the description never says so or contrasts it with any sibling tool.

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