Vulnerabilities Summary

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

With no annotations, the description carries the full behavioral burden. It discloses the data source (Grail security.events) and a group cap (max 100), which is useful, but says nothing about permissions, pagination/truncation behavior once the cap is hit, or whether long-range queries are prohibited without allowLongRange.

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 efficient sentence with the source and cap front-loaded and zero filler. It is appropriately terse for its content, though it leans toward under-specification rather than genuine conciseness.

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 10-parameter tool with no annotations and no output schema, the description is far too thin. It omits output shape, defaults for the many time-range parameters, truncation semantics at 100 groups, and any guidance on the overlapping security/compliance siblings.

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 80%, so the schema already documents most parameters including time windows, connection, and allowLongRange. The description adds no parameter meaning beyond the schema, which is the expected baseline at high coverage.

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: summarizing vulnerability findings sourced from Grail security.events, plus a scope bound (max 100 groups). This lets an agent know it is a read-only summary tool, but it does not distinguish itself from close siblings like dynatrace_compliance_findings or dynatrace_security_events_summary, which also summarize security data.

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?

There is no when-to-use guidance, no exclusions, and no named alternatives despite a crowded sibling set of security and compliance tools. An agent must infer from the name alone that this is for vulnerability triage rather than compliance or generic security events.

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