picus_get_device_signatures

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

No annotations are provided, so the description carries the full burden. It mentions the output fields ('signature_id, name, vendor_severity, product_platform/version, etc.') and the relationship ('mitigate the given actions'). However, it does not disclose read-only nature, authentication needs, or any side effects, leaving gaps.

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 brief (two sentences) and front-loaded: first sentence states core purpose, second adds constraints and output fields. Every word adds value, though it could be slightly more structured.

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 tool has 2 parameters, no output schema, and no annotations, the description covers the key purpose, a critical constraint (max 10 action IDs), and the output structure. It is largely complete for a simple lookup tool, though it could include a usage example.

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%, so the description must compensate. It adds meaning to 'action_ids' by specifying it is required and limited to 10 ids, which is not in the schema. However, 'device_id' is not described beyond its schema title, missing an opportunity to explain its role.

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 verb ('Get'), resource ('vendor prevention signature suggestions'), and scope ('for a device and actions'). It distinguishes from sibling tools like picus_get_action_alerts or picus_get_threat by specifying that it returns signatures that mitigate given actions.

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 states that 'action_ids is REQUIRED (max 10 ids)', providing an explicit constraint. However, it does not explicitly mention when to use this tool versus alternatives, nor does it provide prerequisites or conditions. Usage is implied but not fully guided.

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