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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, covering the safety profile. The phrase 'durable status' adds a hint that results are persisted across polls, but nothing is said about polling cadence, terminal states, or freshness, so added context is modest.

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 resource and its qualifier come first. It is minimal but every word carries meaning, though nothing beyond the core statement is offered.

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?

An output schema exists, so return values (job status) need not be described, and annotations carry the safety profile. For a one-parameter read getter this is nearly complete; only the polling/after-start usage context is missing.

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% and the single jobId parameter is fully documented in the schema, so the description has no burden to explain parameters. Baseline 3 applies since the description adds no syntax or format meaning beyond the schema.

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?

Specific verb ('Read') plus resource ('durable status of an automatic finality-observation job'), so an agent knows it fetches persisted job state. It does not explicitly differentiate itself from siblings like priorseal_observe_execution or priorseal_get_receipt, so sibling disambiguation is left to inference.

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 description gives no when-to-use, prerequisites, or alternatives. Given the crowded sibling set of observation/authorization getters, an agent has to infer that this is the polling tool for a job started elsewhere.

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