Threat Intel Advisory Lookup

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. Description adds 'local threat-intel database' context, indicating no external fetch. No contradiction. However, it doesn't detail behavior on missing IDs or performance considerations.

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?

Single, well-structured sentence that is front-loaded and free of redundancy. 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?

Given simplicity (1 param, output schema exists, annotations rich), the description is nearly complete. Minor gap: no mention of error handling or edge cases like invalid IDs, but output schema likely covers return structure.

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 100%, and the schema's parameter description already provides detailed format guidance (e.g., 'CVE-2024-1234 or GHSA-abcd-1234-wxyz'). The tool description adds no new parameter-level information beyond 'one advisory,' so baseline 3 is appropriate.

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 clearly states 'Look up one advisory from the local threat-intel database.' It specifies a specific verb (look up) and resource (advisory from a local database), distinguishing it from siblings like intel_match which likely handle multiple matches.

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 when a specific advisory ID is known, but lacks explicit guidance on when to use this tool versus alternatives like intel_match or intel_sources. No mention of when not to use or prerequisites.

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