# Addy Osmani: agent-skills

**Source**: [github.com/addyosmani/agent-skills](https://github.com/addyosmani/agent-skills)

## Why This Collection

Addy Osmani is a long-standing practitioner in performance and web engineering at Google; his skill collection reflects that lineage — process-driven workflows that encode disciplined engineering rather than prompt tricks. The repository is organized around the software lifecycle (Define, Plan, Build, Verify, Review, Ship) and includes anti-rationalization tables that explicitly counter the shortcuts agents tend to take.

## What's Inside

- 20 skills mapped to six lifecycle phases, including `spec-driven-development`, `test-driven-development`, `code-review-and-quality`, `security-and-hardening`, and `ci-cd-and-automation`
- Agent personas (code reviewer, test engineer, security auditor) for role-specific behavior
- Mandatory verification gates rather than suggestions

## Value for Practitioners

Closest in spirit to this handbook's "agent-ready environment" framing. If you are designing skills for a team and want a reference for phase-by-phase coverage, this is the most complete public example. Treat the lifecycle taxonomy as a checklist: if your own skills leave a phase uncovered, that's a gap worth naming.
