devtools_detach

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

With no annotations provided, the description carries the full burden of disclosing behavior, but it only names the action. It does not say that detaching ends an active DevTools session, whether the operation is idempotent, or how it affects subsequent devtools-related tools.

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 a single, front-loaded sentence with no filler or repetition. For a simple one-parameter tool, this is appropriately concise and scannable.

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?

The basics are present: what the tool does and which tab it targets. However, for a state-changing tool with no annotations, it would benefit from stating that the tab must have an attached DevTools session and what happens to CDP operations after detachment. The gap is moderate because the tool is otherwise very simple.

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 single required parameter tabId is reasonably self-explanatory from its name and type. However, schema description coverage is 0% and the description does not explicitly explain that tabId identifies the currently attached tab, so the agent gets little added semantic guidance.

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 uses a specific verb ('Detach') and names the exact resource ('Chrome DevTools Protocol from a tab'). It unambiguously identifies the operation and is the clear inverse of the sibling devtools_attach, so an agent can distinguish it without inspecting the schema.

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 gives no guidance on when to detach versus any alternative, nor does it mention prerequisites such as first attaching DevTools. The intended context is only implied by the verb and the sibling tool name.

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