Fullstack Dev Skills Pack

Six agent skills that make a coding agent work like a disciplined senior fullstack engineer: tests first, security on every change, attacking its own code, clean integration between UI and server, and safe release and operations.

What’s in the pack

Skill Phase Loaded when
dev-core Every code change Always, on any coding task (also holds the routing table)
backend-dev Build: server Server code, APIs, DB, migrations, jobs, data/system design
frontend-dev Build: UI Components, pages, forms, client state, UX/product quality
fullstack-integration Connect Work touching both sides of an API, contract changes, stale data / type / error-handling bugs
ship-and-operate Release & run CI/CD, Docker, IaC, env/secrets, health checks, flags, rollout/rollback, SLOs
debug-production Fix in prod Bugs and incidents in deployed environments

The skills use the open Agent Skills format (a folder with a SKILL.md), so the same files work in Claude Code, Claude.ai, OpenAI Codex, Cursor, GitHub Copilot, Google Antigravity and other agents that support the standard.

Principles

  • Tests first. Red, green, refactor. A bug fix starts with a failing test that reproduces it.
  • Security on every change. A five-action security pass on the diff, plus a full checklist for high-risk work.
  • Break it. After building, the agent switches roles and attacks its own feature (only locally or in test environments it controls), then turns every successful attack into a test and a fix.
  • No evidence, no claim. Every check is reported with its command and observed result. Anything that didn’t run is reported as “not verified”.
  • Stop and hand back. The agent returns control when it’s done, blocked, needs a decision, would cross a risk line, or has failed three times on the same problem.
  • Production is read-only. No deploys, infrastructure applies, migrations or production data changes without explicit approval in the conversation.

Quick start 

git clone https://github.com/Singhak/dev-skills.git
cd dev-skills
./install.sh /path/to/your-repo          # macOS / Linux / WSL

powershell -ExecutionPolicy Bypass -File .\install.ps1 -Repo C:\path\to\your-repo   # Windows

Then ask your agent “which skills do you have available?” to confirm. Full platform details are in Getting started.
