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

With minimal annotations, the description carries the full burden of transparency by listing prerequisites (Bearer token, existing owned NEED watch), operational mechanics (binding a canonical comparison request), and constraint boundaries (no automatic retry).

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 highly efficient, using one complex sentence to cover prerequisites, all three operations, and constraints. It maintains a tight structure, though its density slightly lowers the score from a perfect 5.

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?

The tool is highly complex, requiring definitions for three different operations and multiple parameters. The description comprehensively covers prerequisites, operational mechanics, and error handling philosophy (explicit caller decision on conflict).

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?

Given that schema description coverage is 0%, the description is vital. It explains the functional meaning of the core parameters, such as that 'bind explicitly attaches a canonical comparison request' and 'review checks the current accepted documentary build.'

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 differentiates between the three primary operations (`bind`, `review`, and `get`). It specifies that this tool handles internal documentation of a watched choice, which is distinct from tools like `list_watches` or `get_plan`.

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 provides critical boundary conditions, stating explicitly that the tool performs 'No new watch, purchase or notification,' and mandates that 'A conflict requires an explicit caller decision,' guiding the agent on when not to use it.

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