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

With no annotations, the description carries the full behavioral burden, yet it only discloses the plan requirement. It does not say whether this contacts real stores autonomously, whether commitments/charges are irreversible, expected latency, or rate limits — critical for a tool that performs real-world outreach.

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?

Two tight sentences plus a link, front-loaded with the capability and the plan constraint. The key-generation URL is somewhat tangential but compactly stated.

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?

For an action tool with a required undocumented parameter, no annotations, and no output schema, the description is too thin: it omits the parameter meaning, the expected behavior/return, and the real-world consequences of triggering negotiation agents.

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 single required 'context' parameter has 0% schema description coverage, so the description must compensate — and it never mentions the parameter at all. An agent is left guessing what 'context' should contain (product, target store, negotiation goal?).

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 names a specific action and resource: it triggers agents that negotiate price/conditions directly with the local physical store on the customer's behalf. That is distinct from the read-only siblings (search products, list stores, live leads), though the differentiation is left implicit rather than stated.

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 discloses a gating prerequisite (Enterprise plan required), which is useful usage context. However, it never states when to prefer this over the sibling tools or in what scenarios negotiation is appropriate, leaving usage to inference.

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