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

With no annotations provided, the description carries the full burden for behavioral transparency. It does not mention side effects, authorization requirements, failure behavior, or what happens with invalid signatures. It only states what the action is, not its broader behavior or guarantees.

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, focused sentence with no unnecessary fluff. It packs the key action, recipient, and proof mechanism efficiently.

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?

Given the lack of annotations and output schema, the description is too thin for full context. It does not explain the purpose of each parameter, the return value, error cases, or how this interacts with the other memory-related tools.

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 coverage is 0% and no parameter descriptions are provided. The description partially explains id, readerPubKey, and timestamp by including them in the EIP-191 signature format, but wrappedKey and signature are not defined beyond their names.

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 tool's specific action: a creator registers a wrapped content key for a specific reader's public key, with proof via an EIP-191 signature. This distinguishes it well from the sibling tools such as read_memory, extend_memory, store_persistent_memory, and share_memory_key.

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 description does not explicitly state when to use this tool versus the sibling tools. It implies use by a creator for registering a key release, but there is no direct comparison with share_memory_key or other alternatives.

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