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

There are no annotations, so the description bears the full burden of behavioral disclosure. It clearly reveals the keyless authentication flow, the action_required='sign_envelopes' response, and the required permission scopes. It does not describe failure conditions, but the critical authorization behavior is transparent.

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 compact and every sentence carries useful information: the core operation, the no-arg list mode, filename mode, and the keyless envelope handshake. The behavior is front-loaded and the details are structured clearly without padding.

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?

The description covers the normal list and download workflows well, including keyless specifics and the envelope re-call pattern. However, receipt_id and encoding are never mentioned, and since all parameters are optional with no schema descriptions, an agent may not know when or why to use those parameters. This is effective but incomplete.

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?

With 0% schema description coverage, the description must compensate for all parameter meaning. It usefully explains filenames and envelope, but it never explains receipt_id or encoding. Because two of the four parameters remain semantically unexplained, parameter coverage is only partial.

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 identifies the operation ('list files or download content') and the resource ('your Nukez locker'), and it distinguishes list mode from download mode. It does not explicitly differentiate from sibling tools like nukez_recall, so it falls just short of full sibling distinction.

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?

It provides explicit usage conditions: call with no filenames to list, call with filenames to download, and for keyless servers, call first without envelope then re-call with signed envelope. It does not discuss when to prefer an alternative sibling tool, but the primary usage guidance is concrete and actionable.

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