pending_action_create

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

Discloses that the action is not immediately executed and requires whitelisted types, which informs safety. However, does not mention error handling for invalid types or state changes.

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?

Single sentence conveys core purpose and constraints. Effective but could be slightly more structured.

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?

Given no annotations and 0% schema coverage, the description partially compensates but lacks parameter details and explanation of what 'pending action' means in practice.

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 has 0% description coverage; the description only hints at action_type constraints. No explanation of title or params fields.

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 clearly states it creates a pending action, specifies constraints (whitelisted action types) and behavior (no immediate execution). This distinguishes it from siblings like confirmed or canceled actions.

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 implies use for creating actions without immediate execution, but does not explicitly contrast with alternatives like pending_action_confirm or pending_action_cancel.

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