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

No annotations are provided, so the description carries the full burden. It usefully discloses a per-call cost of $0.01 and that the verdict is 'precomputed' (i.e., retrieved rather than computed), but it says nothing about what happens when no verdict exists, whether the call is read-only, or whether anything is mutated by the manifest-change-trigger check.

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?

Two short sentences with the core fact (what it returns, plus cost) front-loaded and zero filler. Slightly cramped — the 'Args:' list is terse to the point of being note-like, but nothing is wasted.

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 three undocumented parameters, no annotations, and no output schema, the description should do far more work than it does. It never explains what a verdict contains, what happens on a cache miss, or how the optional hashes change the response — the agent is left to call this largely blind.

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%, so the description must compensate, and it only partially does. It restates the parameter names and marks two as optional, and hints at the purpose of manifest_hash/shared_line_hash ('manifest-change-trigger checking'), but dataset_id has no semantic explanation and none of the three parameters' formats or interaction is clarified.

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 identifies the resource — a precomputed signed verdict for a dataset — but uses a noun phrase with no verb (fetch/retrieve), so the action is only implied. It also does not distinguish itself from the sibling verify_verdict, leaving the agent to guess which of the two to call.

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 explicit when-to-use or when-not-to-use guidance, and the sibling verify_verdict is never mentioned as an alternative. The only implicit guidance is the '(\$0.01)' price tag, which hints at cost sensitivity but never says when paying for a precomputed verdict is preferable to verifying one yourself.

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