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

With no annotations, the description carries the full burden, and it does disclose content scope (all five tiers, Nostr keygen instructions, next steps), which implies a read-only informational retrieval. It does not explicitly state that the call is side-effect free, nor mention any authentication or rate-limit behavior, so the safety profile remains inferred rather than declared.

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, front-loaded with the core purpose before the coverage detail. Minor redundancy in listing tiers and then summarizing contents ('practical next steps'), but nothing wasteful enough to impede selection.

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 informational tool with an output schema covering the return shape, the description supplies what an agent needs: what the guide is, what tiers it covers, and that it includes keygen instructions. The only omission is how it relates to the register_*/request_citizenship siblings.

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 schema takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a no-param tool applies. The description correctly implies the tool is parameterless by describing a fixed, tier-spanning guide.

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 — a tier-specific onboarding guide for joining the DPYC Social Contract — and enumerates its five tiers and contents, so an agent can tell it returns guidance rather than performing a registration. It does not, however, contrast itself with informational siblings such as about, get_rulebook, or economic_model, so sibling differentiation is left to inference.

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 only implied: an agent can guess this guide should be read before invoking register_advocate, request_citizenship, or confirm_citizenship, but the description never states that sequencing or names those alternatives. No when-not-to-use or prerequisites are given.

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