agent-skills (Addy Osmani)
A collection of twenty-four engineering practices packaged as installable skills for a coding agent: review, testing, performance, accessibility, documentation. Authored by Addy Osmani, who spent years on web performance at Google. MIT licence, one-command install, and a structure designed so the agent only loads the skill that is useful at the moment it is useful.
Strengths
- Production-proven practices, written by someone whose craft this has long been
- A structure loading only the useful skill, instead of permanently saturating context
- MIT licence and one-command install on the common coding agents
Limitations
- A prescriptive method that will clash with your own conventions if installed wholesale
- Twenty-four skills with steps and checks: the bill is paid in context consumed
Best for
- Understanding how to translate an engineering practice into instructions an agent actually applies
- Comparing your own method against a public one written by a practitioner
