frida_cloak_thread

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

With no annotations, the description should fully disclose behavioral traits. It only states 'Hide a thread' and explains parameters, but fails to mention side effects, reversibility, required privileges, or return values. This is insufficient for a mutation tool.

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?

Extremely concise with no unnecessary words. The purpose is stated first, followed by parameter descriptions. Every sentence adds value.

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 thread hiding (a low-level operation) and the lack of output schema, the description is incomplete. It does not explain the impact on the target process, whether the operation is reversible, or what the return value indicates. For a potentially disruptive tool, more context is needed.

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%, so the description must fully explain parameters. It does so for both parameters: 'target' (process name or pid) and 'thread_id' (OS thread id, with default behavior when None). The explanations are clear and match the schema structure.

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 ('Hide a thread'), the resource, and the API used ('Frida Cloak API'). It distinguishes the tool from siblings like frida_cloak_fd and frida_cloak_range by specifying the target is a thread.

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 explicit guidance on when to use this tool versus alternatives (e.g., other cloaking tools). The description does not provide when-not-to-use or prerequisites, leaving the agent without decision support.

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