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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds value beyond that by disclosing the shape of each returned record (title, company, location, apply link), which matters since there is no output schema. It stops short of stating volume, ordering, or whether results are paginated/truncated.

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 compact sentence with the resource front-loaded and the payload described after the colon – no filler. It reads as a fragment rather than a full sentence, but every clause earns its place.

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 no parameters and no output schema, the description carries the burden of explaining what comes back, and it does name the four fields. It is still silent on result count, ordering, freshness ('open' is undefined), and pagination, which are the remaining things an agent would want before relying on the output.

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 there is nothing for the description to disambiguate; the baseline for a parameterless tool is 4. The field list it does provide describes the response rather than inputs, which is a bonus rather than a gap.

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 (open jobs on the CodeDebut jobs board) and enumerates the returned fields (title, company, location, apply link), so an agent can tell this is a jobs listing distinct from the product-oriented siblings. It never uses an explicit verb like 'list', but the intent is unambiguous.

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?

Usage is only implied by the phrase 'open jobs on the CodeDebut jobs board' – there is no statement of when to call this versus alternatives, and no exclusions or prerequisites. In practice the sibling set is entirely product/category focused, so the domain separation does most of the routing work, but the description itself contributes nothing explicit.

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