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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered; the description adds a real operational fact in the required scope/permission. It says nothing about pagination limits or ordering despite page/per_page parameters existing.

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?

Two sentences, scoping and payload contents front-loaded, permission requirement last. Zero filler.

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 paginated list with a full output schema and clear annotations, the description covers what is listed, what comes back, and the auth requirement. Only pagination/result-size behavior is left unstated, which is a minor gap given the output schema.

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 description coverage is 71% and the description contributes no parameter meaning at all, leaving account routing (zoneOrId, accountId, account_slug, environment_slug) and pagination entirely to the schema. Baseline 3 is appropriate since the schema does most of the work, but no value is added.

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 and resource ('List account Load Balancer pools') plus the payload shape ('with origins and health summary'), which distinguishes it from cf_load_balancers_list and cf_lb_monitors_list by resource type. It does not explicitly name those siblings as alternatives, so it stops short of a 5.

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?

Adds a permission prerequisite ('Requires Account Load Balancers Read') but never says when to choose this over cf_load_balancers_list or cf_lb_monitors_list, nor when pool listing is the wrong call. Usage is implied by the resource name rather than stated.

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