Finalize claimed tabs

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that the tool releases ownership, does not close tabs, and detaches CDP attachments on all claimed tabs, including kept claims. It also clarifies that 'keep' entries preserve handoff/deliverable claims. This is transparent and covers key side effects, though it could mention reversibility or permission requirements.

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 two sentences, front-loading the primary action. It is compact and each sentence adds relevant information: the main effect, a critical exception (no tab close), and a behavioral detail (CDP detach). No fluff or repetition, though it could be slightly more structured.

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 the tool's simplicity (one optional parameter, no output schema), the description covers the essential operational details: what it does, what it preserves, and what it detaches. It does not specify the scope of 'claimed tabs' (e.g., session-wide), but sibling tools like 'claim_tab' provide context. The absence of output schema is acceptable since no return value is defined.

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 schema description coverage is 0%, so the description must compensate. It explains that 'keep' preserves handoff/deliverable claims, which adds meaning beyond the schema. However, it does not elaborate on the 'status' enum values or the significance of 'sessionTabId', nor does it specify that 'keep' is optional. While it partially compensates, some parameter semantics remain implicit.

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's action: releasing browser-control ownership state for claimed tabs. It also specifies what it does NOT do (does not close user tabs) and that it detaches CDP attachments. However, it does not explicitly differentiate from the sibling tool 'release_tab', so an agent may need to infer the difference. Still, the core purpose is unambiguous.

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?

No guidance is given on when to use finalize_tabs versus release_tab or cdp_detach. The description does not mention typical scenarios, prerequisites, or conditions that would lead an agent to choose this tool over alternatives. It only describes the mechanism, not the context of use.

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