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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so safety is covered. The description adds real behavioral content by enumerating what the snapshot contains (provenance, prior values, open question, unread words, sent status, offer). However it says nothing about error behavior when an id/token pair is stale, or about size/shape of the payload.

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?

It is a single compact sentence with no filler, which is appropriately sized for a read tool. But the payload is delivered as an unstructured comma list of undefined terms, so the agent has to guess what 'where it came from' or 'words not yet read' concretely map to.

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, so the description carries the full burden of describing the return value; it makes a genuine attempt by enumerating six facets of the snapshot. It stops short of describing the shape of those facets or how nested provenance is presented, which leaves the agent under-informed for a tool with no output schema.

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 100% and both parameters carry their own descriptions, including the uuid format and the 48-hex token pattern with the privacy warning. The description adds no further meaning about id or token, so the baseline of 3 applies.

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 the resource ('A Latent Mile requirement') and, via the title, the read intent ('as it stands'), so an agent can infer it returns a snapshot. But it never states a verb in the description body and leans on domain jargon ('Latent Mile', 'words not yet read', 'open question') that a fresh agent cannot resolve. It does implicitly contrast with edit_requirement by framing the result as current state, but only weakly.

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 statement, no mention of alternatives like edit_requirement or inspect_offer, and no prerequisites such as when the token is available. The read-only framing is implied by 'as it stands' but nothing routes the agent between this tool and its many siblings.

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