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

Annotations already declare readOnlyHint and idempotentHint, so safety is covered; the description still adds real value by documenting the return shape (including 'kind' enumerating fix/workaround/guidance) and the empty-result contract 'has_guide=false', which matters because no output schema exists.

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 dense sentences, front-loaded with purpose and followed by the return payload and the negative case. The field list is compact and every clause carries information an agent would otherwise have to discover by calling.

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 single-parameter read tool with no output schema, the description adequately covers what is returned and what happens when nothing is published. It stops short of explaining how fix versions or steps are structured when a guide exists, but nothing essential to invoking it is missing.

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 is one parameter at 100% schema description coverage, so the schema already explains cve_id fully. The description only restates 'for a CVE' and adds no format, normalization, or accepted-id guidance beyond that baseline.

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 and resource ('published remediation guide for a CVE') and enumerates exactly what comes back: summary, steps, workarounds, caveats, kind, and fix versions. That content profile implicitly separates it from lookup_cve or search_cves, though no sibling is named outright.

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?

Usage is only implied: an agent infers it should call this when it needs remediation steps for an already-identified CVE. There is no explicit when-to-use versus lookup_cve, check_version, or product_cves, and no stated prerequisites such as whether the CVE must be tracked first.

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