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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the baseline is met. The description goes further with genuinely useful behavior: the meaning of a null return, the full semantics of changeStatus (CHANGED/UNCHANGED/UNKNOWN), that UNKNOWN never refuses, and that repeating the read is safe after an ambiguous publish.

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?

The description is dense but every clause earns its place, packing return shape, conditional fields, enum meanings and the post-publish interpretation into a few sentences. The heavy backtick/em-dash compression hurts readability somewhat but avoids redundancy.

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 carries the full burden of explaining return values and it does so thoroughly: what `site` contains, when it is null, what additional fields appear with `archiveId`, and how to interpret statuses after an ambiguous publish. Nothing essential for correct invocation or interpretation is missing.

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 100%, so the baseline is 3, but the description adds real semantics beyond the schema: it names the fields `archiveId` unlocks (`publish` with allowed/reason/message/failedAt), explains changeStatus values, and ties `archiveChanged` to whether a new revision was created.

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 states a specific resource (the game's sandbox page) and discloses what the read yields (`site` with link/status/live revision, or null). It implicitly distinguishes itself from publish_sandbox by framing itself as the reader of the refusal that publish would give. However, it never explicitly contrasts its scope against other state-reading siblings like get_archive_status or get_sandbox_share.

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?

Usage is implied through the `archiveId` case (to learn whether a publish would be refused) and one explicit scenario: after a publish with no answer, to determine whether it landed. There is no explicit when-to-use versus alternatives and no when-not guidance, and no routing among the many sibling state tools.

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