Addy Osmani's Agent Skills
25 production-grade engineering skills for AI coding agents covering the full lifecycle from spec to ship, installable into 70+ agents.
Why it matters
Lifecycle skills with verification gates and anti-rationalization checks from a well-known Chrome engineering lead; 100K+ stars.
What you could build with it
An indie developer or small team could install the pack into their coding agent so every feature goes through spec, plan, build, test, review, and ship gates, enforcing senior-engineer discipline automatically.
Does it hold up?
103K+ stars and 10K+ forks show massive adoption; install is one npx command into 70+ agents. Concrete quality gates (TDD, constraint-driven development) are documented. Evidence of measured production impact is anecdotal rather than benchmarked.
