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

No annotations exist, so the description carries the full burden. It discloses the useful traits of authority and fast-changing content, but says nothing about what a call actually returns, whether it performs network access, or any latency/rate considerations - gaps that matter for an unannotated tool.

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 short sentences, zero waste, with the identification of the resource front-loaded before the usage trigger. Nothing in it is redundant with the name or schema.

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 zero-argument tool with no output schema, the description is complete about purpose but underspecified about the return value - it never says whether the agent gets URLs, article titles, or summaries. An agent could still decide to call it, but cannot predict what it will receive.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. Schema coverage is 100% and no argument semantics are missing.

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 concrete resource: authoritative, regularly updated sources for AI-driven attacks and AI-system security. It is distinguishable from lookup_cve or check_known_exploited by its AI-attack focus and its 'freshness' framing, though it never names those siblings 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?

"Fetch them when freshness matters" gives a clear positive trigger and implicitly contrasts with the built-in knowledge base, which is stale by comparison. There is no explicit when-not condition or named alternative tool, but the selection context is unambiguous for a zero-parameter fetch.

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