syzkaller-build-loop SKILL.md skillA
syzkaller-build-loop from benchflow-ai/benchflow is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add benchflow-ai/benchflow/syzkaller-build-loop@git:20260610.e2a435fPins git:20260610.e2a435f in mdr.lock. Pin the fingerprint instead.

Full build workflow for adding new syscall descriptions to syzkaller.
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
# Syzkaller Description Workflow ## Full Build Loop for New Descriptions When adding new syscall descriptions, follow this workflow: ```bash cd /opt/syzkaller # 1. Write/edit your .txt file in sys/linux/ # 2. Create a .const file with constant values (see syz-extract-constants skill) # The .const file should be named: sys/linux/your_file.txt.const # 3. Compile descriptions make descriptions # 4. Build syzkaller make all ``` ## Quick Rebuild (After Minor Edits) If you only changed descriptions (not constants): ```bash cd /opt/syzkaller make descriptions # Runs syz-sysgen to compile descriptions ``` If you add new constants, update the `.const` file first. ## Common Errors ### Unknown type ``` unknown type foo_bar ``` - Type not defined, or defined after first use - Define all types before using them ### Constant not available / defined for none of the arches ``` SOME_CONST is defined for none of the arches ``` - The constant isn't in the `.const` file - Add it to `sys/linux/your_file.txt.const` with the correct value ### Missing reference ``` undefined reference to 'some_type' ``` - Type defined in another file not being found …

How to install
mdr add benchflow-ai/benchflow/syzkaller-build-loop@sha256:36d455ae98e5dfe1The line at the top of this page pins the label git:20260610.e2a435f, 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.
