devtools_disconnect

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

With no annotations present, the description carries the full burden and fully discloses side effects: resumption, removal of session-set breakpoints only, badge removal, and tab-claim release. It even conditions one effect ('if it is paused at a breakpoint') and scopes another ('we set').

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 expresses the core verb first, then a tight colon-separated list of side effects, ending with the usage directive. No filler or redundancy.

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 parameterless cleanup tool with no output schema, the description covers what it does, the conditionality of one action, the side effect on the tab claim, and when to call it. Nothing necessary for selecting and invoking it is missing.

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 has zero parameters and an empty schema, so parameter semantics are trivially covered; the baseline is 4. The description reinforces that invocation requires no arguments.

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 opens with 'Detach cleanly' and enumerates concrete effects: resume paused page, remove breakpoints, remove badge, release tab claim. This clearly identifies a distinct cleanup operation and contrasts with sibling devtools_connect.

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 an explicit trigger: 'Always call this when you are done.' This tells the agent exactly when to invoke the tool and implies it is the terminal cleanup step, so no alternative cleanup tool is needed.

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