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

With no annotations, the description carries the full behavioral burden. It discloses one useful constraint (the 1000-payload cap), but says nothing about what canonicalization actually does, whether the operation is deterministic, how per-payload errors in the batch are surfaced, or whether the call is atomic. For a batch mutation-style tool this is a significant gap.

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?

A single front-loaded sentence with no filler; the batch limit, the resource, and the call-count efficiency are all packed in without redundancy.

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 is no output schema and no annotations, so the description must carry the return and failure semantics itself. It is adequate for identifying the call but leaves open what the response looks like and how partial failures in a 1000-item batch are reported.

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 coverage is 100%, so the 'payloads' array and its stringified-JSON item format are already documented. The description adds the array-size ceiling of 1000, which the schema does not state, giving it marginal value above the baseline.

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 names a specific verb ('canonicalize'), the resource ('JSON payloads'), and the batch scope ('up to 1000 ... in one call'), which implicitly separates it from the singular 'canonicalize' sibling. It never names that sibling explicitly, so the differentiation is inferred rather than stated.

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 'batch ... in one call' phrasing implies when to reach for this over the single-payload sibling, but no explicit condition or alternative is given. There is no guidance on when batching is inappropriate or how failures are handled.

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