execute_action

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does disclose two key behaviors: executing the action and recalculating the live workflow. However, it does not mention permissions, reversibility, error conditions, or other side effects. The 'approved' qualifier adds useful context about a precondition, but the overall disclosure is still sparse.

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?

The description is a single, concise sentence that front-loads the verb and captures the essential behavior. It contains no filler words and is appropriately sized for a simple tool. Under-specification is not penalized here, as other dimensions cover completeness.

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?

Although an output schema exists, the description is inadequate for a mutation tool with no annotations. It does not clarify the meaning of 'planned action', the parameter roles, or the post-execution state beyond recalculation. Given the surrounding tools (planning, simulation, rollback), an agent needs more context about prerequisites, side effects, and the action lifecycle. The description is too thin to fully guide correct invocation.

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?

The input schema has zero description coverage for all three parameters (actionId, workflowId, principalId), and the description does not mention any of them. There is no explanation of what an action ID is, what principalId represents, or the role of workflowId. With 0% schema coverage and no compensating parameter details, the description completely fails to help an agent understand the parameters.

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 uses a specific verb ('execute') and resource ('planned action'), and it clearly states the action's primary effect. It distinguishes the tool from siblings like plan_next_actions and rollback_action by focusing on execution of an approved action. The phrase 'approved planned action' adds clarity about the lifecycle stage.

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?

The description does not provide explicit guidance on when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or references to sibling tools. The phrase 'approved planned action' implies a precondition but does not elaborate on how approvals are obtained or when to choose this over plan_next_actions or rollback_action.

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