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 adds substantive content disclosure — that rollbacks, skips and their reasons are surfaced, that plugin versions are held back after a rollback, and that hardening settings are included — which is real value beyond the annotations. It stops short of return format, time-window limits, or pagination.

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?

It is a single sentence, so it is compact, but it is a comma-spliced enumeration of fragments ('safe updates or deactivations Relvato made and their outcome') with no lead verb and no prioritization among the listed categories. Front-loading the generic domain rather than the primary purpose weakens the structure.

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 only one fully documented parameter, no output schema, and a closed-world read-only annotation profile, the description carries the return-content burden and does so reasonably well by enumerating the data categories returned. The gaps are the unbounded 'recent windows' and lack of any volume or paging expectation, which are minor against the overall coverage.

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 required parameter (siteId) with 100% schema description coverage, so the schema already carries the semantics. At high coverage the baseline is 3; the description adds nothing about siteId format, scoping, or whether it accepts slugs versus numeric ids.

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 is a noun-phrase inventory of what is returned (update policy, recent windows, rollbacks, held-back plugin versions, Relvato-initiated updates, hardening settings) rather than a verb-led statement of what the tool does. The domain is clear, but it never names the action ('retrieve/get') and does not distinguish itself from close siblings like get_safe_update or get_activity_log. Adequate but with a clear framing gap.

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?

There is no when-to-use, when-not-to-use, or alternative-tool guidance. With siblings such as get_safe_update, get_activity_log, and get_quarantine covering adjacent territory, an agent gets no signal on which to pick. The content list only implies usage.

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