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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds that the tool supplies a copy-ready prompt and numbered steps sourced from specific URLs, but it does not disclose caching, update frequency, or other behavioral traits beyond the static content description.

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 a single, front-loaded sentence that packs purpose, content type, and provenance without filler. Every component earns its place.

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, read-only tool with rich annotations but no output schema, the description sufficiently explains what content is returned (prompt and numbered steps) and where it comes from. It could explicitly state the return format, but the provenance and content description are adequate.

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 the baseline is 4. The schema has no parameters to document, and the description appropriately does not invent parameter semantics.

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 states the resource and content: onboarding steps for mining PoA, including a copy-ready prompt and numbered steps. It does not explicitly name a verb like 'returns' or distinguish from similar siblings, but no sibling overlaps this unique onboarding resource.

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?

Usage is implied by the phrase 'How to start mining PoA,' but there is no explicit when-to-use guidance, no exclusions, and no named alternatives. Since no sibling tool provides onboarding content, the lack of alternatives is less problematic, but the description does not state conditions for invocation.

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