extension_reload

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 successfully warns that the extension 'will briefly disconnect and automatically reconnect,' alerting the agent to a temporary service interruption. However, it fails to disclose whether this clears extension logs, affects active browser tabs, requires specific permissions, or if the operation is idempotent.

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 consists of two efficient sentences with no redundant filler. However, the placement of '[Disabled]' at the beginning creates a slight structural awkwardness, as it appears to be a metadata tag injected into the description body rather than a narrative sentence.

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 simple zero-parameter administrative action, the description covers the core mechanism and immediate side effects (disconnection). However, given that this is a destructive/interruptive operation with no output schema, it should ideally indicate whether the operation returns success status or how to verify the reload completed successfully.

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 the schema coverage is trivially 100%. Per the rubric, this establishes a baseline of 4. The description does not need to compensate for missing parameter documentation, nor does it add unnecessary parameter-related text.

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 reloads the OpenTabs Chrome extension (specific verb + resource). However, the '[Disabled]' prefix at the beginning creates ambiguity—it is unclear whether this indicates the tool is currently non-functional or if it is part of the action description, slightly muddying the clarity.

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 provides no guidance on when to use this tool versus close siblings like 'extension_force_reconnect' (which merely reconnects) or 'extension_check_adapter'. It does not state prerequisites (e.g., when the extension is unresponsive) or when this aggressive reload is preferable to other recovery options.

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