frida_process_attach_thread_observer

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

With no annotations, the description carries full burden. It only mentions a bounded window but does not explain what happens when the duration expires, how events are collected, or any side effects. Behavioral transparency is very limited.

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 extremely concise at one sentence. While it is efficient, the lack of detail for a tool with multiple parameters and no annotations reduces its effectiveness. Still, it is well-structured.

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 3 parameters (none described), no output schema, and no annotations, the description is insufficient for complete understanding. It does not explain the return value, parameter defaults, or the behavior beyond a bounded window.

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 adds no meaning to the three parameters (target, duration_seconds, event_limit). The agent cannot infer what each parameter controls from the description alone.

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 it calls GumJS Process.attachThreadObserver() for a bounded window, indicating the verb and resource. It distinguishes from the sibling 'module observer' tool by the resource type, but does not explicitly highlight the difference.

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 usage guidelines are provided. The description does not specify when to use this tool over alternatives like frida_process_attach_module_observer or any other sibling tools. The 'bounded window' hint is weak guidance.

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