list_missing_updates

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

readOnlyHint=true already signals a safe read, and the description meaningfully adds the paged return shape {total, offset, has_more, items}, the limit bounds (default 20, max 200), and that `contains` is a server-side filter over item fields. This goes beyond the annotation with concrete paging/filter behavior; only rate limits or auth needs are absent.

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?

Three tight sentences, front-loaded with purpose before mechanics, and each sentence carries distinct information (purpose, return shape/bounds, filter semantics plus paging advice). No filler.

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, the description usefully describes the page envelope and the `total` field that gates paging, plus filter semantics. It is nearly complete; only the meaning of `offset`/`org_id` and the nature of returned items are left implicit.

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 description coverage is 0%, so the description carries the param burden. It documents `limit` (default 20, max 200), implies `offset` via the paging guidance, and explains `contains` as a server-side text filter with examples; only `org_id` is left to its self-evident name.

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 clear verb (List) and specific resource (missing OS/third-party updates) scoped 'across an organization', which implicitly separates it from endpoint-level siblings like list_endpoint_missing_updates. However, it never names an alternative tool, so the differentiation from list_vulnerabilities and the endpoint-scoped siblings is left to inference.

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?

Provides operational guidance ('check `total` before paging through everything') and explains what `contains` filters on, which implies how to page efficiently. It does not state when to prefer this org-wide listing over list_update_missing_endpoints or list_vulnerability_endpoints, so alternative-selection guidance is missing.

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