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

With no annotations, the description carries the full burden, and it delivers the single most important behavioral fact: the tool is not yet implemented and will open a GitHub PR against the registry. That is exactly the kind of context an agent needs. It still omits auth requirements, whether the caller must own the npub, and reversibility, so it is not a 5.

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 purpose before the implementation caveat. Every clause carries information, though the em-dash split between 'not implemented' and the PR mechanism reads slightly awkwardly.

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?

An output schema exists, so return values need not be explained, and the not-implemented status is disclosed. However, for a mutation-style tool with zero annotation coverage, the description leaves authorization and identity-binding questions open, which matters for a registry-changing operation.

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?

Schema description coverage is 0% for the single required parameter 'npub', and the description never mentions the parameter, its expected format (Nostr public key), or whether it must match the caller's own identity. The word 'member' only loosely gestures at it, leaving the parameter effectively undocumented.

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?

States a specific verb and resource ('Citizen self-removal from the DPYC Social Contract') and the mechanism (automated PR), which is clear enough to separate it from operator-side tools like deregister_operator. It does not explicitly name a sibling to route against, so it stops short of a 5.

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?

The phrase 'Citizen self-removal' implies the use case (a member leaving voluntarily), but there is no statement of prerequisites, no named alternative (e.g., how this differs from deregister_operator or confirm_citizenship), and no exclusions. Usage must be inferred.

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