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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, but the description adds substantial context beyond them: the four status values, the trust meaning of unattested or server-overridden entries, and the safety note that notices never ask for keys or funds. That is genuine behavioral disclosure rather than restatement.

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 core field enumeration is delivered as one long run-on clause before the actionable guidance appears, so the most useful sentence ('Use it before acting on a notice...') arrives late. The detail is justified because there is no output schema, but the front-loading is weak and could be split for scannability.

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?

With no output schema and zero parameters, the description carries the full burden and discharges it: it enumerates returned fields, status values, the G0 key provenance, and the trust caveat. An agent has everything needed to call it and interpret results correctly.

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 no parameter semantics to explain and the baseline of 4 applies. Nothing in the description misleads about inputs.

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 (minepoa system notices and release manifests) and a specific enrichment (POAScan's check of the G0 publisher signature), so the agent knows exactly what comes back. It is clearly distinct from siblings like get_network_summary or get_transaction, which do not carry signature-verification semantics.

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 gives explicit trigger conditions: 'Use it before acting on a notice, or to confirm a release is genuine,' plus a caution that non-verified results are informational only. No alternative tool is named, but no sibling appears to overlap, so the absence of an 'instead use X' pointer is minor.

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