How Google’s Open‑Source Agent Skills Tackle AI Laziness
The article introduces Addy Osmani’s open‑source Agent Skills, a 19‑skill package that embeds Google’s engineering constraints into AI programming tools, providing commands for each development phase and a built‑in “no‑excuse” table to prevent AI from skipping specs, tests, and reviews.
AI programming assistants often skip specification documents, testing, and security reviews, resulting in code that fails after deployment.
Addy Osmani packaged a Google‑engineered workflow into an open‑source collection called Agent Skills , comprising 19 skills that span the entire development lifecycle.
Define : requirement analysis and PRD writing
Plan : task breakdown
Build : incremental development, API design, front‑end engineering
Verify : test‑driven development, debugging, browser testing
Review : code quality, security hardening, performance optimization
Ship : Git workflow, CI/CD, documentation, release
Each skill embeds Google’s hard constraints—“Spec before code”, “Tests are proof”, and “Faster is safer”—to enforce disciplined development.
7 shortcut commands
/spec– define what to build /plan – plan the construction /build – incremental build /test – verify functionality /review – conduct code review /code-simplify – simplify code /ship – ship to production
Invoking a command activates the corresponding skill set for that stage of the workflow.
Each skill also contains a “no‑excuse” table that directly counters common AI shortcuts such as “I’ll add tests later” or “The requirement is simple, no doc needed”.
