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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: the 'Free, read-only' cost/auth note and a substantive explanation of the playbook's contents (shot list, reference rules, corrections).

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?

Three tight sentences, front-loaded with the verb, resource, and id provenance before the explanatory definition. Minor redundancy in 'Free, read-only' against the readOnlyHint annotation, but it adds the 'free' cost signal.

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 read-only, two-parameter tool with no output schema and full schema coverage, the description supplies the domain context (what a playbook is) and the id source, which is enough to invoke correctly. Return-value expectations are the only thing left implicit.

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%, so the baseline is 3, and the description earns a bump by explaining the origin of the id parameter ('ids come from load_video_workflow'), which the schema does not say. It does not, however, mention the optional 'resource' parameter at all.

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 ('Load') and resource ('one shared production playbook by id') and explicitly distinguishes itself from the sibling load_video_workflow by naming it as the id source. The second sentence defines what a playbook actually is, so an agent can tell this apart from the many other load_/list_ 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?

It tells the agent where the required id comes from (load_video_workflow) and what the load accomplishes ('apply it to your production'), which is clear usage context. It stops short of stating when not to use it or naming a preferred alternative beyond the id source.

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