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

No annotations are provided, so the description must carry the full behavioral burden. It implies a write operation ("File") and discloses that filer identity is the caller's account, but it omits permissions, signature validation behavior, side effects, error conditions, rate limits, and response behavior.

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 with no filler. Its parenthetical adds useful identity and tier context efficiently, though the overall brevity leaves major gaps covered under other dimensions.

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?

There are no annotations, no output schema, 0% schema description coverage, and a nested payload object, making correct invocation difficult from this definition alone. The description provides some high-level context but not enough detail about required fields, signing mechanics, or outcomes.

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 schema includes a nested `fields` object plus `signature` and optional `public_key`. The description only hints at signing and identity handling; it does not explain the payload structure, signature format, or the role of `public_key`.

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 states a specific action and resource: "File a signed hazard bulletin." It also clarifies that the filer identity comes from the caller's account and mentions Fleet/Feed-API tiers. It does not explicitly distinguish this tool from siblings such as preflight_check or submit_receipt.

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 gives a tier constraint ("Fleet/Feed-API tiers") but does not say when to use this tool versus preflight_check or submit_receipt. There is no explicit when-to-use, when-not-to-use, or alternative-routing guidance.

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