check_local_inventory

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

No annotations are provided, so the description carries full responsibility. It explains the process of iterating model-file/hash pairs and verifying checksums on the staging server. However, it does not detail what happens on mismatch or the tool's side effects, leaving some uncertainty.

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 well-structured with a brief summary, command equivalent, and parameter documentation in a consistent format. It is appropriately sized for the tool's complexity and front-loads the main purpose.

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 that an output schema exists (not shown), the description does not need to explain return values. It sufficiently covers purpose, parameters, and behavior, making it complete for the provided context.

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 description adds meaning to both parameters beyond the input schema. It explains that empty model means all configured models and empty config_path uses default search. This is valuable since the schema itself provides no parameter descriptions.

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 verifies local firmware checksums against config.ini inventory, with a specific verb and resource. It gives a command equivalent for context. However, it does not explicitly distinguish from sibling tools like check_remote_packages or check_upgrade_readiness.

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 notes that no device connection is required, implying usage when offline verification is needed. It provides an equivalent command hint, but lacks explicit guidance on when to use this tool versus alternatives, and does not mention when not to use it.

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