B3.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description usefully adds that include_live reads live targeting without rerunning the task or changing ads, which is a genuine behavioral disclosure beyond the annotations. It stops short of noting authorization or rate-limit details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with the primary purpose front-loaded and the include_live caveat second. Minor stylistic issues (mid-sentence capitalization) but no wasted content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

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 need not be explained, and annotations cover the safety profile. However, with 6 undocumented parameters and no sibling routing guidance, an agent would still be guessing about several inputs.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 6 parameters, so the description must carry the load. It only explains include_live; task_ref, copy_offset, result_cursor, copy_generation, and connection_context are left entirely undocumented in both schema and prose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb (reads) and resource (the create/copy task's saved ad copy and failures), so an agent knows exactly what data comes back. It does not, however, explicitly contrast itself with nearby siblings like tasks_get_status or tasks_latest.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It clarifies include_live's behavior but never states when to use this tool versus alternatives such as tasks_get_status, tasks_latest, or tasks_list. Usage is only implied by the verb 'read' and the 'saved ad copy' scope.

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