frida_anti_debug_bypass

Bypass debugger detection in a target process by hooking ptrace, sysctl, and other anti-debugging mechanisms, enabling dynamic analysis.

Instructions

Bypass debugger detection mechanisms in a target process.

Hooks: ptrace(PT_DENY_ATTACH) -> return 0, sysctl P_TRACED -> clear, ObjC isDebuggerAttached -> false, getppid -> 1 (launchd), Android Debug.isDebuggerConnected -> false.

target: process name or pid (string). Returns a list of successfully installed bypasses.

Behavior4/5

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

The description details the specific hooks installed (ptrace, sysctl, ObjC, getppid, Android Debug.isDebuggerConnected) and states the return value is a list of successful bypasses, giving good insight into its behavior without annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (~100 words), front-loaded with the main action, then lists hooks, parameter, and return value in a logical, scannable format with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with no output schema, the description adequately explains what the tool does, how it works (specific hooks), what input is needed, and what is returned, making it self-contained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description explicitly defines the 'target' parameter as a process name or PID (string), adding critical context beyond the bare schema type declaration (100% schema coverage compensated).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool bypasses debugger detection mechanisms, with specific hooks listed (ptrace, sysctl, etc.), which distinguishes it from sibling tools like anti-root or SSL pinning bypass.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 other bypass tools (e.g., anti-root, AMSI bypass). No prerequisites or contextual advice is provided.

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