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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description does add one behavioral fact not in structured data — the call is free — and hints at return content ('status and timing'), but says nothing about pagination, limits, or how 'recent' is bounded.

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 short sentences with the resource and scope front-loaded and no filler. The terse 'Free' fragment is unconventional but does convey cost information efficiently.

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 simple read-only list tool whose annotations carry the safety profile, the description covers purpose but leaves the required 'workflow' identifier format and limit semantics unspecified, and no output schema exists to fill the return-shape gap.

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 0%, so the description must carry the parameter burden and does not: it never explains whether 'workflow' is a name, ID, or slug, nor what 'limit' defaults to or caps at. Only the loosely implied association between the workflow and its runs is conveyed.

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?

The description gives a specific verb+resource ('List recent runs of a workflow') and adds scope detail ('status and timing'). It is clearly distinct from the singular sibling hyreflow_workflow_run and from hyreflow_workflows_list, though it never names those siblings explicitly.

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?

There is no guidance on when to use this versus hyreflow_workflow_run or hyreflow_workflows_list, and no prerequisites or exclusions are stated. The only usage signal is the implied cost note 'Free', which is about pricing, not selection.

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