athena_hall_of_immortals

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

The description adds some behavioral context: the Hall of Immortals is 'chronological append-only', suggesting a read-only, immutable list. It also states a prerequisite ('fresh shared frontier sync'). However, with no annotations, it fails to disclose side effects, return format, pagination behavior, or error conditions, leaving significant transparency gaps.

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 a single sentence with no filler words, making it efficient and front-loaded with the verb 'Return'. It is appropriately concise in form, though brevity comes at the cost of missing detail.

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 tool with three optional parameters, no output schema, and no annotations, the description provides only a minimal outline. It fails to explain what the 'Hall of Immortals' is, what each parameter does, or what the return value contains, leaving the agent under-informed. The precondition 'fresh shared frontier sync' is mentioned but not defined.

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 schema has three parameters (limit, remote, shared_remote_mode) with zero description coverage. The description provides no explanation of any parameter, leaving the agent to guess what 'remote' and 'shared_remote_mode' control. This is insufficient compensation for the schema's lack of descriptions.

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 uses the specific verb 'Return' and identifies a unique resource ('P5 Hall of Immortals'), distinguishing it from all sibling tools which don't mention this concept. The phrase 'chronological append-only' clarifies the nature of the returned data. This is a clear, non-tautological purpose statement.

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?

The description implies a usage condition ('after a fresh shared frontier sync'), providing some context on when to invoke this tool. However, it does not mention alternatives, exclusions, or when this tool should be preferred over other retrieval tools. Thus, it relies on implication rather than explicit guidance.

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