frida_open_channel

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

Without annotations, the description carries full burden. It states 'Open and close' but does not clarify whether it opens and then automatically closes, or if the user must also call 'frida_channel_close'. It also lacks details on side effects, synchronization, or expected behavior.

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, making it concise, but it tries to cover two actions and a purpose in one go, leading to potential ambiguity. It is front-loaded with the verb but lacks structure.

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 has 2 parameters, no output schema, and many sibling tools, the description is too brief. It does not explain parameter usage, exact behavior (e.g., does it close automatically?), or prerequisites, leaving significant gaps for an agent.

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%, and the description does not mention or explain the parameters 'address' and 'device_id'. It adds no meaning beyond the schema, which is minimal. The agent gets no guidance on what values to provide.

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 specifies the verb 'Open and close' and the resource 'raw Frida device channel', and distinguishes it from siblings like 'frida_channel_open' and 'frida_channel_close' by adding 'as a readiness probe', indicating a test operation. However, the dual action is somewhat ambiguous.

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 implies the tool is for readiness probing via 'as a readiness probe', but it does not explicitly state when to use this tool over alternatives like 'frida_channel_open' or 'frida_channel_close', nor does it provide usage context or exclusions.

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