meta_horizon_developer_latest_snapshot

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It adds useful context that the tool avoids returning a large payload, implying a performance/bandwidth advantage. However, it does not disclose whether the operation is read-only, has side effects, requires auth, or what happens if no snapshot exists.

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, front-loaded sentence that conveys the core purpose and key limitation (not the large payload). Every word earns its place, achieving maximum conciseness without empty filler.

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?

Given the low complexity (2 params, no output schema), the description should at least explain parameter semantics and when to use the tool. It fails on both counts, leaving critical gaps for correct invocation. The brief mention of metadata/health and payload size is insufficient for a tool with zero schema descriptions.

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 description coverage is 0%, and the description does not explain the parameters app_id or snapshot_dir. Since both are required, the lack of any semantic guidance means an agent is left guessing their purpose. The description must compensate for the schema gap but does not.

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 clearly states the verb 'Return' and the resource 'latest snapshot metadata and collection health,' and distinguishes itself from returning the large payload. This differentiates it from sibling tools like meta_horizon_developer_read_operation, which likely retrieves the payload itself.

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 usage when metadata or health is needed without the heavy payload, but it does not explicitly state when to use this tool versus alternatives like read_operation or collect. No exclusions or alternative tool names are mentioned.

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