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

With no annotations, the description carries the full burden and does disclose two meaningful traits: the call is billable and subject to 'ingest discipline' (validation/acceptance rules). It does not state whether the signing is done server-side or must be supplied, whether the operation is idempotent, what permissions are required, or what happens on duplicate/rejected records.

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 wasted clauses; the resource and its key behavioral hook (billing/ingest parity) come first. It is tight, though the compression into jargon costs some readability.

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?

This is a mutating, billable tool with no annotations, no output schema, and an unconstrained nested object parameter. The description leaves the record's required fields, signing responsibility, failure behavior, and cost implications undefined, deferring to an external endpoint spec the agent may not have access to.

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 single parameter is a nested object with 0% schema description coverage, and the description only restates it ('{record}') plus the word 'signed'. The internal shape of the record object — the one thing an agent actually needs — is entirely undocumented, pointing instead to an external POST /records contract.

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?

States a concrete verb (emit) and resource (one signed census record), which is specific enough to act on. No sibling (account, register_producer, subscribe, verdict, weekly_report) overlaps with record emission, so explicit differentiation isn't required, but the jargon ('census record', 'signed') is left undefined.

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 clause 'same ingest discipline and billing as POST /records' gives an implied mental model — use this where you'd POST a record — but there is no explicit when-to-use, when-not-to-use, or prerequisite/permission guidance. Usage is only inferable from the external endpoint reference.

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