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

With no annotations, the description must carry the behavioral load, and it does disclose two meaningful traits: results are ranked toward the least-invasive path, and the output is explicitly not a compatibility approval. It omits any note on authorization requirements beyond 'owner-authorized' or on result volume, but the disclosed caveats are operationally valuable.

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 sentences, front-loaded with what the tool returns and immediately followed by the actionable caveat and prerequisite. Every clause earns its place with no 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?

An output schema exists, so return values need not be explained, and the purpose plus prerequisite are covered. However, for a 5-parameter search tool with 0% schema coverage, the absence of any parameter guidance leaves the agent guessing how to steer results.

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 5 parameters, and the description adds no meaning for query, device_id, limit, intervention, or risk_tolerance. The two enums are self-describing in the schema, but the description does nothing to explain how risk_tolerance or intervention shape which playbooks are returned, which is exactly the gap the description should fill.

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?

It states a specific verb (find) and resource (curated owner-authorized firmware/local-protocol/cloud-replacement playbooks), which distinguishes it from the singular get_firmware_playbook. It does not explicitly contrast itself with that sibling or with assess_hackability, so an agent must infer the difference from the plural-collection framing.

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 gives a clear prerequisite chain: call check_firmware_compatibility before preparation, and results are explicitly 'not compatibility approval.' That routes the agent to the right sibling at the right step. It stops short of saying when to prefer this over get_firmware_playbook for retrieving a specific playbook.

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