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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the response contents in useful detail, and 'Get' implies a non-destructive read, but it says nothing about behavior for an unknown id, rate limits, or auth requirements.

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 tight sentences: the return payload leads, then the usage condition. No filler, no repetition of the name or title, and every clause carries information an agent needs.

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?

With no output schema and no annotations, the description compensates well by enumerating the returned fields (summary, CVEs, severity, fix versions per distribution). For a single-parameter read tool that is everything an agent needs to select and call it correctly.

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?

Only one parameter and schema description coverage is 100%: the schema already documents 'id' with the exact example format ("APSB24-40"). The description restates 'by id' without adding syntax or lookup semantics beyond the schema, so the baseline of 3 applies.

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 and resource ('Get one security bulletin by id') and enumerates the payload (summary, CVEs, severity, per-distribution fix versions), which implicitly separates it from the plural sibling get_security_bulletins. It never names a sibling explicitly, so the distinction must still be inferred from 'one' vs. the list tool.

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?

Gives two concrete triggering conditions: the user names a specific bulletin id, or asks which patch fixes a given CVE. No alternatives are named and no exclusions given, and the second condition overlaps with find_patch / check_version_security territory, leaving some routing ambiguity.

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