Threat Level

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is covered. The description adds that the value is 'computed' and 'current', implying it's a derived metric. Beyond that, it doesn't disclose behavior like caching, refresh semantics, or what 'computed' entails, though this is minor for a read-only getter.

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 sentence that efficiently states the purpose and output format with zero waste. It includes the meaningful detail of the 0-25 range to set expectations. 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?

There is an output schema present, so return-value documentation is covered. For a zero-parameter read-only getter with good annotations and a defined output schema, the description is reasonably complete. It could arguably add what 'threat-landscape' encompasses, but the output schema likely covers the structure. The single-sentence description is adequate for this tool's simplicity.

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?

There are zero parameters, making parameter semantics largely moot. With schema description coverage at 100% and no parameters, the baseline of 4 applies. The description goes slightly beyond by explaining the output is a 0-25 rating, which clarifies what the returned value represents.

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?

Description states a specific verb+resource: 'Get the computed current threat-landscape level'. It even clarifies the output is a 0-25 rating of overall posture. However, among many sibling tools (get_landscape_briefing, get_threat_level vs get_recent_threats, etc.), it doesn't explicitly differentiate from alternatives beyond the narrow scope of 'current' stated level.

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 usage via 'computed current threat-landscape level' — this is a snapshot of present posture, distinct from briefing-style or historical tools. However, there's no explicit when-to-use or when-not-to-use guidance, nor naming of alternative tools for comparison, which is notable given 70+ siblings.

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