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

With no annotations, the description carries the full behavioral burden. It does reveal versioning and conditional rate-limit counters, but it leaves crucial behavior unclear: what a 'TERM greeting bundle' is, what versioning means, whether authentication is required, and what the response contains.

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 short and front-loaded in length, but its clarity suffers from dense, non-standard phrasing like 'Versioned TERM greeting bundle' and 'ride the transport headers.' It is concise in word count but not in communicative efficiency.

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?

The tool has no output schema and no annotations, so the description must explain what the agent receives and when the call is meaningful. It does not describe the greeting format, the versioning scheme, or the nature of the rate-limit counters, leaving the agent with an ambiguous model of the tool.

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 has zero parameters arid the schema already exhaustively documents that with an empty properties object. Per the zero-parameter baseline, the description does not need to add parameter-level meaning.

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 restates the noun form 'greeting' and adds opaque jargon like 'TERM' and 'bundle', but never clearly states what the tool returns or accomplishes. It does not distinguish this from the many other get_* siblings, such as get_briefing or get_pulse.

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 guidance on when to use this tool or when to prefer an alternative. The conditional clause about signed credentials describes a personalization side effect, not a selection criterion.

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