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

readOnlyHint=true already tells the agent this is a safe read, so the description's main contribution is disclosing what is returned: trigger, action, enabled state and run count. It says nothing about ordering, pagination, or whether disabled workflows are included, which matters for a list tool.

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?

One compact sentence with no filler, and the resource is front-loaded before the returned fields. It could have been one clause shorter, but nothing is wasted.

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 params and no output schema, the description carries the burden of explaining return shape, and it does list the main fields. It stops short of volume/ordering behavior and of clarifying the boundary against the three other list_workflow* siblings.

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?

Zero parameters, so there is no per-parameter semantics to convey and the baseline of 4 applies. The description correctly implies the list is scoped to the authenticated coach rather than accepting a filter argument.

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?

A specific verb plus clearly scoped resource ("the coach's workflows (automations)"), with a parenthetical disambiguating jargon. It does not explicitly name a distinguishing sibling like list_workflow_runs or list_workflow_templates, so an agent must infer the split from the noun alone.

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?

No when-to-use or when-not-to-use guidance, and no routing among the several adjacent workflow tools (list_workflow_runs, list_workflow_approvals, list_workflow_templates, set_workflow_enabled). The intended usage is only implied by the tool name.

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