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

With no annotations, the description must carry the behavioral burden, and it does disclose the free/no-payment property and the informational read nature of the call. It omits other behavioral traits such as rate limits, freshness/refresh behavior, or whether the endpoint is a passive view, though the presence of an output schema relieves it of return-format detail.

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?

Three sentences, front-loaded with the '[FREE]' tag and the tool's purpose before the return list. The 'Watch live at https://...' sentence is promotional rather than operational and is the one mildly expendable line.

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 a zero-parameter status tool with an output schema, the description supplies enough context: the domain (contract negotiation between house-brain agents), what the call returns at a high level, and the cost profile. Nothing essential for invoking it correctly is missing.

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 tool takes zero parameters, so per the rubric the baseline is 4. There is no parameter information the description could usefully add, and it correctly refrains from inventing any.

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 gives a specific resource ('Live status of DCCN') and elaborates on what DCCN is (an AgentPay negotiation engine with shifting contextual signals), which lets an agent understand the tool's domain without opening the schema. It does not, however, contrast itself against the many sibling '*_live' status tools (alloy_live, covenant_live, evidence_room_live), so differentiation is left to the distinctive 'DCCN' name.

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?

No explicit when-to-use or when-not-to-use statement is given, and no alternative tool is named. Usage is only implied by the nature of a 'live status' tool and by the '[FREE] ... no payment required' marker, which hints that it can be called without cost concerns.

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