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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is clear. The description adds that it reads an owned job and receipt and mentions 'Downstream writes proceed only on continue by default', but that latter phrase is ambiguous and does not clearly explain behavior beyond the annotations.

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 short and front-loads the main action. However, the second sentence about downstream writes is cryptic and may not earn its place without clarification; overall it is concise but not optimally structured for understanding.

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?

For a simple read-only tool with clear annotations and no output schema, the description covers the basic action. It falls short by not explaining what an 'operational receipt' is or what the return value includes, leaving the agent to infer details from the name and siblings.

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?

With only one parameter (job_id) and 0% schema description coverage, the description should compensate. It says 'owned job', hinting that job_id refers to an owned job, but does not explain that job_id is the identifier for the quality check job or provide format details.

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 verb 'Read' and resources 'owned job and operational receipt', and explicitly clarifies 'does not start another check', which distinguishes it from start_quality_check. The term 'operational receipt' is somewhat vague, but the core action is clear.

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 only guidance is a negative one ('does not start another check'), implying use start_quality_check to initiate. There is no explicit when-to-use guidance relative to other getter siblings like get_quality_report or get_quality_baseline, nor are alternatives named.

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