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

With no annotations, the description provides a complete behavioral profile: mandatory human approval flow, displaying specific context (paused_reason, customer's last words), and an alternative UI/URL action.

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?

While extremely dense and detailed, it is highly efficient, containing all necessary business logic and failure states in one block without unnecessary 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?

Given the complexity and the multi-step nature of this specific use case, the description is exhaustive and complete for an AI agent attempting to handle this workflow.

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?

Since schema coverage is 0%, the description is vital. It explains that owner_confirmed is not just a boolean toggle but a flag granted only after a preceding human verification step is completed.

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 identifies the specific resource (text thread), the action (start texts again), and critical scoping constraints (must be paused and customer stopped-like).

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?

It provides strict usage guidelines, including who can use it ('Owner only'), prerequisite checks (is it paused?), and exclusion criteria (on the stop list).

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