facilitator_live_dashboard

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

No annotations are supplied, so the description carries the full disclosure burden. It implies a read-only snapshot view and discloses the two content components, but says nothing about freshness/lag of 'live' data, result limits on 'the last settled transactions', or whether any authentication is required. For a zero-parameter read tool the risk is low, but these are real gaps.

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 short sentences with the payload definition front-loaded before the human-facing URL. Every element earns its place, though 'aggregate pulse' is unexplained jargon and the trailing human URL is of marginal use to an agent.

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?

There is no output schema, so the description is the only source of return-value information, and it only names the two components without describing their structure, fields, or size. Combined with silence on freshness and auth, it is adequate to select the tool but thin for interpreting results.

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 no parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The schema confirms an empty object with additionalProperties false, matching the description's 'in one call' framing.

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 resource ('x402 settlement transparency dashboard') and states the exact payload: an aggregate pulse plus the last settled transactions in one call. This is concrete enough to distinguish it from the narrower siblings get_settlement_pulse and get_recent_settlements, but it never names those siblings, so the differentiation is 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?

'In one call' hints that this is the combined alternative to calling the pulse and recent-settlements tools separately, which is useful implied guidance. However, there is no explicit when-to-use or when-not-to-use statement, and no mention of when an agent should prefer get_settlement_pulse, get_recent_settlements, or check_facilitator_liveness instead.

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