9arm-skills

9arm-skills is a curated collection of agent skills organized for engineering, productivity, and personal AI workflows. Each skill lives in its own directory and includes a SKILL.md file with frontmatter plus any supporting scripts or reference files. The repository is designed to be installed into AI coding-agent environments so agents can follow reusable operating procedures. Its engineering skills focus on practical development behaviors such as debugging, scrutiny, review, and postmortem writing. The productivity side provides reusable patterns for non-code tasks and daily workflows. 9arm-skills is most useful for users who want their AI agents to behave with more discipline, consistency, and context-specific structure.
