browser_keep_alive_stop

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 mutation-like action. It never says what happens to the tabs once pinging stops (do they get discarded/suspended?), whether the call is idempotent, or what happens if tab_ids reference invalid/closed tabs.

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?

Very short and front-loaded, with the core action in the first sentence and the parameter behavior second. The Python-docstring 'Args:' style adds a little structural overhead but wastes no words.

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 one-optional-param tool with no output schema and no annotations, the essentials are present. However, the post-condition (what stopping the pinger means for the tab's lifecycle) is left unstated, which is the main missing element for an agent reasoning about side effects.

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?

Schema coverage is 0%, so the description must compensate, and it does: it explains that tab_ids identifies 'Tabs to stop pinging' and that omitting or passing null means 'stop all' – matching the schema's default of null and anyOf null type.

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 states a specific verb+resource ('Stop the keep-alive pinger') and its scope ('some or all tabs'), so the agent understands exactly what it does. It doesn't name the counterpart sibling browser_keep_alive, but the pairing is obvious from the name.

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 only usage instruction is about the parameter ('Omit (or pass null) to stop all'), not about when to invoke this tool versus alternatives. There is no mention of browser_keep_alive or any condition that selects this tool over others.

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