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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false, so the safety profile is fully covered. The description adds the return structure (jobs grouped by category with their playbook agents), but says nothing about pagination, ordering, or completeness of the listing.

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 that describes what is listed and how the results are organized, with no filler or redundancy.

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 output schema the description usefully explains the shape of the result (category grouping plus associated agents), which is the key thing an agent needs. However it omits the optional category filter entirely, leaving a real gap for a tool whose only parameter is undocumented.

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 0% and the sole parameter (category, an enum of ten values) is never mentioned in the description, so an agent reading prose alone would not know filtering by category is possible. The description fails to compensate for the documentation gap in 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?

States a specific verb (Lists) and resource (jobs the Agents Handbook covers) and describes the grouping and the agents attached to each job, which is more informative than a bare restatement. It doesn't explicitly contrast with siblings like search_playbooks or get_agent, so it stops short of full differentiation.

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 context, no prerequisites, and no alternative tools to prefer. An agent must infer that this is a browse/discovery entry point rather than a filtered search.

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