assembly-x86 SKILL.md skillA
assembly-x86 from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/assembly-x86@git:20260905.fd53e99Pins git:20260905.fd53e99 in mdr.lock. Pin the fingerprint instead.

Use when reading GCC or Clang x86-64 assembly, writing inline asm, decoding AT&T syntax, or applying System V AMD64 register rules. Not for SIMD intrinsic selection: use simd-intrinsics.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# x86-64 assembly GCC and Clang emit AT&T syntax by default. This skill reads that output, writes inline asm, and keeps register use inside the System V AMD64 ABI. ## Contract | Field | Bound contract | |---|---| | Trigger | The task reads compiler assembly output, writes inline asm in C or C++, decides AT&T versus Intel syntax, or explains calling conventions and stack layout in a disassembly. | | Authority | Read-only. The skill explains and drafts; edits land through the normal coding path. No remote mutation. | | Side effect | None. | | Done | The drafted assembly assembles with `gcc -c` or `clang -c`, or the compiler output under discussion is explained register by register. | ## Inputs - The C or C++ source, compiler output, or assembly fragment: required. - The compiler: required. AT&T versus Intel output and inline asm details follow it. - The ABI: required. System V for Linux and macOS; the Microsoft x64 ABI changes the register map entirely. ## Procedure 1. Generate the baseline. Read the compiler's own output before writing any. Done when: the disassembly of the function under discussion is on screen. ```bash gcc -O2 -S -fverbose-asm foo.c -o foo.s …

How to install
mdr add outlinedriven/outline-driven-development/assembly-x86@sha256:1422f962b0011d7cThe line at the top of this page pins the label git:20260905.fd53e99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
