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

Goes well beyond the annotations: discloses that it spends workspace credit, delivers for real, sits behind an approval gate, may return needs_confirmation, and is fire-and-forget with specific follow-up tools named. This is exactly the behavioral context an agent needs before invoking a real-delivery side-effecting call.

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?

Dense but front-loaded: the core action comes first, followed by scope, cost/approval caveats, and follow-up. Every sentence carries distinct, actionable information with no 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?

No output schema exists, but the description compensates by telling the agent the run is fire-and-forget and naming workbench_flows_schedules_list (lastStatus) and workbench_executions_get (trace) as the way to observe results. Nothing material is missing.

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 100%, so all four parameters are already documented in the schema. The description's mention of the approval gate and needs_confirmation adds indirect context for approvalId, but it does not add syntax or format detail beyond the schema. Baseline 3 is appropriate.

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 ('Runs one iteration of a schedule immediately through the real scheduled pipeline') and pins the exact scope: same input, same delivery, no cadence change. This clearly distinguishes it from workbench_flows_run and workbench_flows_schedules_update.

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?

Explicitly says when to use it ('Use it to test a schedule the user just set up') and adds a useful edge case ('Works on paused schedules'). It stops short of naming the alternative tools (e.g., workbench_flows_run) or stating when NOT to use it, so it is clear context without full routing guidance.

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