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

With no annotations, the description carries the behavioral burden. It discloses the scope, the error/fatal filter, ranking, and the fingerprint linkage, but it does not describe the return shape, pagination behavior, or whether resolved alerts are included by default. The resolved filter is left to the schema.

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 sentences, no filler. The primary action is front-loaded and the resolver linkage is a useful addition. Every word earns its place.

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 simple list tool with two optional parameters and full schema coverage, the description is nearly complete. It identifies the output concept (fingerprint) and connects it to resolve_alert. A return-format description would push it to a 5, but it is not essential for correct invocation.

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 100%, so the baseline is 3. The description adds no parameter-specific semantics beyond the schema, but it does not need to because the schema already explains limit and resolved. No additional meaning is lost.

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 states a specific verb ('List'), resource ('tracked error/fatal alerts'), scope ('for this project'), and ordering ('ranked by occurrence count'). It is clearly distinguishable from generic log or cost tools and even hints at the follow-up action via the fingerprint.

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 implies this is the tool for browsing alerts and mentions that fingerprints can be used with resolve_alert, but it does not explicitly say when to choose this over get_recent_errors or query_logs, nor when to avoid it. Context is clear, but exclusions are missing.

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