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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so safety is covered. The description adds real behavioral value beyond them by defining the returned states (in_progress, submitted_pending) and the conditions that produce each, including the resume URL case. It stops short of describing refresh/timing behavior for queued deliveries.

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 front-loaded with the primary case and each subsequent sentence earns its place by defining a distinct status branch. The opening sentence is dense with four parallel clauses, which slightly taxes readability but carries no filler.

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 an output schema present the description need not document return values, yet it still explains every status value and the edge case where no assessment has been submitted. Combined with the routing note to my_matches, an agent has everything needed to call and interpret this zero-parameter tool.

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 tool takes zero parameters, so per the rubric the baseline is 4 and there is nothing for the description to disambiguate. No misleading parameter guidance is present.

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 resource (the signed-in evaluating company's latest PreShiftIQ assessment status) and enumerates exactly what it reports: result availability, review state, notified/accepted/queued match counts. It explicitly distinguishes itself from my_matches, so an agent can separate the two without opening either schema.

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?

It gives an explicit exclusion and routing rule: 'Status only; the match list is my_matches,' which tells the agent when to switch tools. It does not, however, address the neighboring status tool my_scorecard_status or state prerequisites such as whether an assessment must exist first.

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