release_session

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

No annotations are provided, so the description carries the behavioral burden. It does disclose the key effect: the session disconnects and the web UI becomes usable by others, which flags that control is being handed off. It omits whether the disconnect is reversible, whether it can be re-taken, and any auth/permission requirement, though the output schema covers return values.

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 front-loaded sentence beginning with the action 'Disconnect from the KVM'. It is efficient, though the trailing 'so the web UI can be used without being taken over' is slightly wordy for the point it makes. No filler or repetition.

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?

For a zero-parameter action with an output schema and no annotations, the description conveys the action and its main consequence (freeing the KVM/web UI for others). The main remaining gap is any note on re-acquiring the session or persistence of the disconnect, but this is minor for a simple release action.

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 no parameter semantics to explain. Schema coverage is reported at 100% and the empty object leaves nothing ambiguous. Baseline 4 applies for a parameterless tool.

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?

States a specific verb and resource ('Disconnect from the KVM'), so an agent knows this ends the current KVM control session. The trailing clause about the web UI explains why, but the phrase 'without being taken over' is slightly indirect rather than crisply naming the session/lock being released. It is distinct from all siblings (which are input/peripheral actions), so no sibling confusion arises.

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 word 'now' implies the session should be released when done, and the description hints at the condition (wanting the web UI usable). However, it never states explicit when-to-use/when-not or names an alternative for re-acquiring control. Usage is implied rather than prescribed.

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