close_hw_manager

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

With no annotations, the description carries the full behavioral burden for a teardown/mutation operation. It does not say whether this disconnects from the hw_server, invalidates device handles or sessions, fails if nothing is open, or is safe to call repeatedly.

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?

A single short sentence with no filler or redundancy. It is appropriately sized, though the brevity contributes to the missing behavioral and usage detail rather than reflecting deliberate compression.

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?

No annotations, no output schema, and no parameters means the description is the only source of behavioral information, and it provides none about side effects, failure modes, or post-conditions. For a teardown tool in a session-managed workflow this leaves meaningful gaps.

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 tool takes zero parameters, so there is nothing for the description to disambiguate beyond what the empty schema already conveys. Baseline for a 0-parameter tool applies.

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 names a specific verb and resource ('Close' + 'Hardware Manager'), which reads clearly as the inverse of the sibling open_hw_manager. It does not explicitly reference that sibling, so the pairing must be inferred from the tool list rather than the text.

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?

There is no guidance on when to call this, what state must exist first (e.g. an open Hardware Manager session, an active hw_server connection), or what happens to dependent operations like program_device. The agent must guess at prerequisites and ordering.

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