solidrpc_create_key

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

Annotations declare readOnlyHint=false, so the agent already knows this is a mutation; the description adds genuinely new behavioral context by explaining idempotent retry semantics. However, it says nothing about whether the key secret is returned once, whether creation is reversible, or what happens on duplicate names, which matters for a create operation.

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 action and followed by the operational caveat; nothing is wasted. The terseness borders on under-specification, but as a structural matter it is clean and easy to parse.

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?

This is a mutation tool with no output schema and 0% schema description coverage, yet the description does not explain what the returned key looks like, whether the secret is shown once, or what 'name' identifies. Given the complexity gaps in both schema and annotations, more prose was warranted.

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%, so the description must carry the load. It explains the intent of idempotencyKey (persist and reuse across retries), which meaningfully supplements the bare minLength constraint, but the required 'name' parameter is left completely unexplained, half the parameters 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?

The description states a specific verb and resource, 'Create an RPC key', which an agent can distinguish from siblings like solidrpc_revoke_key and solidrpc_keys by the verb alone. It stops short of naming an explicit alternative or clarifying how it relates to solidrpc_manage, so it stops at 4 rather than 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 only usage guidance is for retries: persist and reuse the idempotencyKey. There is no statement of when to call this versus solidrpc_keys or solidrpc_manage, no prerequisites, and no note about permissions or quota implications of creating a key.

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