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

No annotations are provided, so the description carries the full disclosure burden. It never says whether this performs a network lookup against a release service, whether it requires auth or is rate-limited, what the response contains (e.g., up-to-date flag, latest version), or that it is a non-mutating read. 'Latest published' hints at a remote call but does not disclose it.

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?

A single front-loaded sentence with no wasted wording; the purpose is immediately clear.

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?

For a simple two-optional-parameter read tool this is adequate in the essentials, but with no annotations and no output schema, the description should say what the check returns (latest version, whether an update exists) and whether a network call is involved.

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% and both parameters (platform, client_version) are documented in the schema with examples. The description adds nothing beyond that, so baseline 3 applies.

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 and resource: compares the installed client version against the latest published tokensafe release. An agent can tell it apart from siblings like get_license_status or get_public_stats, though the description never explicitly names what it is not.

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 only implied by the phrase 'checks the client version' – an agent can infer this is for update/up-to-date checks. There is no explicit when-to-use guidance, no prerequisites, and no mention of alternatives such as get_license_status.

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