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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description contributes genuinely new behavior: results are ordered "worst first" by severity, and the per-finding fields returned are named. It does not say what happens when the asset has no scan or the run id is unknown, nor how the default limit of 20 truncates results.

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 with no filler: the selection rule comes first, the output ordering and field list second. Every clause carries information an agent needs before 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?

With no output schema, naming the returned fields and the "worst first" ordering is exactly the right compensation, and the link to get_security_overview closes the identifier-discovery loop. Remaining gaps are truncation semantics for limit and the empty/unknown-asset case.

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 67% (asset and run_id documented, limit not). The description largely restates the schema's asset wording ("name, target URL or repo ... from get_security_overview") rather than adding new meaning, and it does not clarify whether asset and run_id are mutually exclusive or whether the later limit constrains returned findings.

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?

"Findings from the latest scan of one asset ... or from a specific scan run id" gives a specific resource and scope, plus the returned fields (title, severity, endpoint, CWE). It is clear what the tool returns, but it never distinguishes itself from siblings such as list_cloud_findings or list_attack_paths, so an agent must infer the boundary.

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?

It states the two invocation contexts (per-asset latest scan vs. a specific run id) and points back to get_security_overview as the source of valid asset identifiers, which is a concrete usage path. It stops short of explaining precedence when both asset and run_id are supplied, or when to prefer this over cloud/attack-path siblings.

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