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

With no annotations, the description discloses important behaviors: generates and stores a local ed25519 keypair on first run, only sends the public key, and requires a key from the website. It could mention idempotency or re-enrollment behavior, but overall it provides good transparency for a setup tool.

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 concise (three sentences) and front-loaded with purpose. Each sentence adds unique value: purpose, instructions, and side effects/re-enrollment info. No redundant or extraneous content.

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 schema coverage is complete and no output schema exists, the description covers purpose, usage, and side effects well. However, it does not describe the output/return value or error conditions, which would help the agent understand what to expect. This leaves some gaps for a setup tool.

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?

The input schema already provides descriptions for both parameters (key format and optional label) with 100% coverage. The description adds real-world context: where to get the key, its format (SIGR-XXXXX-...), and the default for device_label. This enhances understanding beyond the schema.

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 purpose: 'Bind THIS device to your SigRank operator so your signed token runs cascade to the live board.' It uses a specific verb ('bind') and resource ('device to operator'), distinguishing it from sibling tools that focus on data retrieval or processing.

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 provides explicit usage instructions: paste a key from signalaf.com, and explains how to obtain a new key. It clearly differentiates this tool from siblings by indicating it is for enrollment/setup. However, it lacks explicit when-not-to-use guidance.

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