cloak_debug_close

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

With no annotations, the description carries the full burden. It states the tool closes a session and releases a seat, which are the key behavioral effects. However, it doesn't disclose potential consequences like losing unsaved debug data, error conditions, or whether it's idempotent. This is a limitation but acceptable for a simple close operation.

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 sentence that front-loads the action and includes a relevant side effect. No wasted words; it earns its place.

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 zero-parameter, no-output-schema tool with no annotations, the description provides the essential purpose and a key side effect. It could mention behavior when no session is active, but the simplicity of the tool makes this adequate.

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?

Since the tool has zero parameters and the schema already covers all fields (vacuously), the description doesn't need to add parameter semantics. The baseline for zero-param tools is 4, and nothing reduces that.

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 ('Close') and resource ('active Cloak debug session'), clearly distinguishing it from siblings like cloak_debug_open or cloak_debug_status. It also mentions the additional effect of releasing the Free-plan browser seat, adding precision.

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 clearly implies when to use this tool—when an active Cloak debug session needs to be closed. It doesn't explicitly mention alternatives or exclusions, but the context is clear enough for a simple close operation. It also notes the seat release, helping the agent understand why this action is important.

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