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

Annotations already establish readOnlyHint=true and openWorldHint=false, so safety behavior is covered. The description adds useful return-content context by listing quotas, next find_jobs eligibility, feed counts, and alert-state limits, though it does not describe response structure or quota-reset semantics.

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 efficient sentence with no filler. The comma-separated list is compact and front-loads the main quota information, though the telegraphed style is slightly less readable than a full sentence.

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 zero-parameter, read-only usage endpoint with no output schema, the description covers the key returned values an agent would need. It could say more about response shape or quota reset timing, but it is sufficient for correct invocation.

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 has zero parameters, so there are no parameter semantics to explain. The baseline for a no-parameter tool is 4, and nothing in the description creates ambiguity about inputs.

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 specifically names the returned information: remaining hourly/daily quotas, next allowed find_jobs time, feed counts, and limits with alert status. It is clearly a usage/quota inspection tool, though the telegraphic noun-phrase style lacks a direct verb and does not explicitly contrast with sibling tools.

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 phrase 'when the next find_jobs is allowed' implies the tool is useful before calling find_jobs, but it never states when to use this tool or when to prefer an alternative. Usage is inferable but not explicitly guided.

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