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

No annotations are provided, so the description carries the full behavioral burden. It does disclose two meaningful traits beyond the schema: the response is 'versioned', and it is augmented with 'live rate-limit counters' conditional on signed credentials in transport headers. It stops short of describing error behavior, what the bundle actually holds, or the rate-limit semantics themselves.

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 compact sentence with the core action front-loaded and the credential-dependent behavior appended. It earns its length, though the 'TERM' token and the semicolon splice add unnecessary density without adding clarity.

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 annotations, no output schema, and no parameters, the description must stand alone, and it is only partially sufficient. It covers the auth condition and one dynamic field, but leaves the return payload's contents and its relationship to sibling read tools undefined, which matters in a toolset crowded with other get_* endpoints.

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?

The tool takes zero parameters, so the schema has nothing to document and the baseline is 4. The description's mention of signed credentials in transport headers is a useful note about implicit transport-level input rather than a schema parameter.

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 names a verb and resource ('Receive the ... greeting bundle'), so the basic action is identifiable, but 'TERM greeting bundle' is opaque jargon and the description never says what the bundle contains or how it differs from sibling discovery tools like get_briefing or get_constitution. An agent would have to guess whether this is a health/hello endpoint or a configuration payload.

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?

It implies a usage condition — personalization occurs 'when signed credentials are presented in the transport headers' — which tells the agent that auth is optional and changes the result. However, there is no explicit when-to-use guidance, no statement of prerequisites, and no routing to or away from any alternative.

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