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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the useful prerequisite that a signature over wallet_link_message's text is required, but says nothing about what linking does, whether the signature is verified server-side, or what happens on failure.

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?

One sentence, front-loaded with the action and resource, with zero filler. It is dense to the point of terseness, which costs a little clarity but nothing is wasted.

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 non-read-only, open-world mutation with five undocumented parameters and no output schema. The description should at minimum explain the key/proof/issued fields and what state change results, but it leaves the agent guessing on most of the call contract.

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% across five parameters, so the description carries the full burden, yet it only gestures at 'signature' and the wallet address. The roles of 'issued', 'key', and 'proof' are completely unexplained in both the schema and the description.

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 ('Link a Solana wallet to your ce-net identity') and points at the sibling wallet_link_message as the source of the signed text, so an agent can tell it apart from wallet_unlink/wallets_linked. It stops short of explicitly contrasting those siblings, which keeps it at 4.

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?

Implicitly establishes the prerequisite workflow: you must first obtain the text from wallet_link_message and sign it. That is clear context for when to call it, though it never states when not to use it (e.g. unlinking, or already-linked wallets).

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