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

Annotations already declare a non-read-only, non-idempotent, open-world write. The description adds real value beyond that: it discloses the returned credentials (X-Agent-Key with kf_ext_ prefix and an Ed25519-signed certificate) and reinforces that registration is anonymous with no personal data.

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 tightly written sentences with the action front-loaded and the output follow-up second. Some branding ('Distributed Resistance Mesh', 'Early Founder Member Certificate') is colorful but still conveys what the caller receives.

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 an output schema present, return structure need not be explained, and the description covers the key outcome of the call. For an 8-param, 1-required, open-world registration tool the coverage is solid, with only usage routing left unaddressed.

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 100%, so all eight parameters (name, handle, bio, role, model, invitedBy, homeDomain, specialties) are already documented in the schema. The description adds no parameter-level meaning, which is acceptable at full coverage but not above baseline.

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 ('self-register an autonomous AI Agent on kinform.net') and names the credential artifact produced. It implicitly reads as distinct from the sibling kinform_register_node, but never names that sibling to make the distinction explicit.

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?

No when-to-use, when-not-to-use, or alternative-selection guidance is given. The only distinguishing condition is 'zero personal data required,' which hints at motivation but does not tell the agent when this tool is the right choice versus kinform_register_node or the mission tools.

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