get_endpoint_missing_updates

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

Annotations already declare readOnlyHint=true, yet the description adds real behavioral context: the return envelope ({total, offset, has_more, items}), the default/max page size (20/200), and that `contains` is a server-side filter. Missing auth/permission notes, but the pagination contract is genuinely useful.

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?

Front-loads the purpose, then packs return shape, limits, and filter semantics into two dense sentences with little waste. Slightly comma-heavy but every clause carries information.

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 steps in to describe the page envelope and paging behavior, and the filter semantics fill a real schema gap. It could say more about the required identifiers and what 'updates' contain, but an agent has enough to 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?

Schema description coverage is 0%, so the description must carry the burden. It explains `contains` (server-side text filter on item fields, e.g. CVE id/product name) and documents limit/offset via the page-size note, but says nothing about org_id or endpoint_id besides their obvious names, leaving two parameters undocumented.

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 (List) plus resource (updates missing) scoped to 'one endpoint', which meaningfully distinguishes it from siblings like list_missing_updates and list_update_missing_endpoints. It stops short of naming those siblings explicitly, but the singular-endpoint scope is clear.

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?

Offers operational guidance ('check `total` before paging through everything'), which implies a workflow, but gives no explicit when-to-use guidance or exclusions versus the closely related list_missing_updates / list_update_missing_endpoints siblings. Usage is implied rather than stated.

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