What it is
Addy Osmani's agent-skills repository packages senior-engineering workflows as skills. The README presents a development lifecycle with commands for spec, plan, build, test, review, simplification, and shipping.
Why it is useful
The pack is broad but coherent. It is useful when you want agents to follow repeatable engineering gates instead of improvising a new process for every task.
Notable skills
-
code-review-and-quality -
debugging-and-error-recovery -
browser-testing-with-devtools -
security-and-hardening -
performance-optimization -
planning-and-task-breakdown
Notes
Because the pack is large, install only the skills you actually want active. Broad lifecycle packs can over-trigger if descriptions are too general for your workflow.
