Agent Skills for Developers
Production-grade skills that make your AI agent debug, test, review and ship like a senior engineer — in Claude Code, Cursor, Windsurf and more.

Workflows, not prompts
Debug faster
Turn bug hunts into a repeatable process: reproduce, isolate, fix, verify — with checklists your agent follows every time.
Ship with tests
TDD skills that make your agent write the failing test first, then the minimal code to pass it. Fewer regressions, calmer deploys.
Review like a senior
Code review skills that catch what linters miss: architecture smells, hidden coupling, misleading names.
Git without fear
Branching, rebasing and release workflows your agent executes cleanly — no more merge-conflict archaeology.
Coding skills
From systematic debugging to TDD — pick the workflow your team needs.
Tidy — AI Code Review
$9A diff/PR reviewer built specifically for agent-written code. Catches AI-slop patterns that line-by-line reviews miss, tiers findings as confirmed vs plausible, and can apply the fixes itself. The differentiator in your review stack.
View skill →Systematic Debugging
$9Stop guessing at fixes. A 4-phase root-cause discipline (reproduce → isolate → hypothesize → verify) that forces your coding agent to find the real cause before touching code. The most-copied debugging skill in the Agent Skills ecosystem.
View skill →Test-Driven Development
$9RED-GREEN-REFACTOR with iron laws: write the test first, watch it fail, then write the minimal code to pass. Turns your agent into a disciplined TDD practitioner that never ships untested code.
View skill →Git Workflow & Versioning
$9Branch strategy, commit discipline, PR hygiene, and release versioning for agent-driven development. Keeps AI-generated changes manageable, reviewable, and reversible at high speed.
View skill →Code Review & Quality
$9Multi-axis code review with severity gates (Critical/High/Medium/Low) across correctness, readability, architecture, security, and performance. By Addy Osmani (Google Chrome). Nothing merges without a verdict.
View skill →Diagnosing Bugs
$9A battle-tested diagnosis loop for hard bugs and performance regressions: reproduce → minimise → hypothesise → instrument → fix → regression-test. Includes a human-in-the-loop helper script. From a working engineer's daily setup.
View skill →superpowers
FreeAgentic skills framework and software development methodology that works (TDD, systematic debugging, planning, verification)
View skill →ponytail
FreeMakes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote.
View skill →caveman
FreeViral skill + proxy for coding agents that cuts 65% of tokens by talking like a caveman.

Your agent is only as good as its workflows.
Give it the ones senior engineers use.
What are agent skills for developers?
Agent skills are reusable instruction packages that teach AI coding agents how to do a job well: a SKILL.md with the workflow, plus references and examples the agent consults as it works. Instead of re-explaining your debugging process in every session, you install it once and the agent follows it every time.
SkillStack's developer skills cover the workflows that matter most in professional software engineering: systematic debugging, test-driven development, code review, git workflows and code quality. Each skill is a complete package your agent can execute — not a prompt you paste and hope.
