frida_channel_open

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

With no annotations, the description must fully disclose behavior. It states the channel is 'kept for stream operations', implying persistence and the need to close it later. However, it does not mention side effects, required permissions, resource allocation, or whether blocking occurs. The agent lacks critical behavioral insight.

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 concise sentence that front-loads the action. However, it is too brief and lacks essential details, making it under-specified rather than efficiently concise.

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 complexity of Frida tools, absence of output schema, and many sibling tools, the description is severely incomplete. It does not explain return values, error handling, or lifecycle management. The agent cannot reliably use this tool based on the description alone.

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% and the description adds no parameter information. The two parameters ('address', 'device_id') are not explained. The description only mentions 'raw device channel', which hints at device but not address. The agent cannot infer the meaning or format of parameters.

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 verb 'open' and the resource 'raw device channel', with the purpose 'keep it for stream operations'. It is distinct from siblings like frida_channel_close, frida_channel_read, and frida_channel_write. However, it does not clarify what a 'raw device channel' is or how it differs from frida_open_channel.

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, such as other channel tools or frida_open_channel. No prerequisites, exclusions, or context provided. The agent would not know when to choose 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.
