frida_channel_close

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

Without annotations, the description should disclose side effects or state changes. 'Close and forget' implies cleanup, but it doesn't clarify what happens to pending operations, error behavior, or if the channel must be valid.

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 with no waste. However, its brevity sacrifices necessary detail, but that is a completeness rather than conciseness issue.

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 purpose in a complex Frida ecosystem and no output schema, the description should explain the return value or success indication, preconditions, and any side effects, which it does not.

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 description coverage is 0%. The description does not explain the parameter 'channel_id' (e.g., how to obtain it, format, or meaning), relying solely on the schema's generic title.

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 action ('Close and forget') and resource ('open device channel'), making it specific and distinguishable from siblings like frida_channel_open, frida_channel_read, etc.

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 on when to use this tool versus alternatives (e.g., frida_channel_close vs other channel operations); no mention of prerequisites like ensuring the channel is open.

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