Activation

This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.

x86 Assembly (Intel) — calling conventions, stack frames, registers, and low-level debugging procedure.
103 charsno explicit “when” trigger
Advanced

Key capabilities

  • →Read x86 assembly for performance or low-level debugging
  • →Understand calling conventions, stack frames, and registers
  • →Trace prologue and epilogue for control flow
  • →Track values through registers and memory operands
  • →Perform safety reviews for alignment and buffer overflows

How it works

This skill provides guidance for reading and debugging x86 assembly by establishing context, tracing control and data flow, and performing safety reviews. It uses standard calling conventions and debugging procedures.

Inputs & outputs

You give it
x86 assembly code or a debugging scenario
You get back
Calling convention and stack frame summary, debugging checklist, and a list of items to inspect

When to use asm-x86

  • →Read assembly code
  • →Debug assembly stack frame
  • →Verify calling convention

About asm-x86

Provides standard calling conventions, tracing instructions for control flow and data, and safety best practices for assembly-level debugging.

x86 Assembly (Intel) — calling conventions, stack frames, registers, and low-level debugging procedure.

When not to use it

  • →The task does not involve x86 assembly
  • →The task is purely about high-level language debugging
  • →The task is about database schema evolution without API surface impact

Limitations

  • →The skill focuses on x86 assembly (Intel)
  • →The skill provides reference for specific calling conventions like `cdecl` and `System V AMD64`
  • →The skill provides reference for specific calling conventions like `Microsoft x64`

How it compares

This workflow offers a structured methodology for assembly-level analysis and debugging, providing specific steps and checks that go beyond generic debugging techniques for higher-level languages.
