AI isn't coming for engineers. It's sorting them.
Into the ones who run agents, and the ones who still do it all by hand. These 30 skills put you on the right side of that line — from a system running 90+ deployed apps with 325 agents and real money on the line.

01 — A Markdown File
Each skill is a SKILL.md file you place in ~/.claude/skills/. No installs. No dependencies. Just a file.
02 — A Slash Command
Type /feature-team <task> in Claude Code and the skill executes — spawning agents, coordinating workflows, delivering results.
03 — Months of Iteration
These aren't first drafts. Each skill has been refined across dozens of real production runs on systems that can't afford to fail.
What's Included
Skill Stacks
Chains that work togetherThe real leverage is the workflow of workflows. Run these in order to take a job from start to shipped.
Ship a feature end-to-end
Idea → spec → built → tested → merge-ready PR
Hunt and kill a bug
Failing behavior → root cause → minimal fix → green
Audit, then remediate
Surface every issue → fix P0→P2 with PRs
Rescue a broken build
Build errors → compiling → covered → verified
Research to spec
Open question → pressure-tested PRD
Harden before deploy
Threat model → pre-deploy gate, no surprises

Copy after unlockingQuality Check
Single-agent coverage scanner. Runs your test suite, ranks your top 5 riskiest untested paths by criticality, and gives you a prioritized fix list — no auto-fix, no parallel agents.
- ›Find your riskiest untested code paths in 60 seconds
- ›Get a prioritized fix list before a PR review
Verify
Pre-PR gate: runs your full build → lint → test → secrets scan loop and produces a PASS / CLOSE / FAIL verdict with a prioritized fix list. Single agent. No auto-fix.
- ›Run a full build + lint + test + secrets check before every push
- ›Get a single PASS / CLOSE / FAIL verdict with a numbered fix list
Scaffold Tests
Zero to test suite in one command. Detects your stack, maps major modules, creates the directory structure, writes one real test file per module, and configures coverage. Gives you somewhere to start — not a finished suite.
- ›Bootstrap a test suite on a repo that has none
- ›Get the right directory structure and config before writing feature code
Build Fix
Auto-diagnoses your build error: isolates the primary failure from cascade noise, traces it to root cause, and gives you one targeted fix. Read-only. No speculative changes.
- ›Diagnose a build failure without manually reading 40 lines of error output
- ›Isolate the primary error from cascade failures in one pass
Auto Fix
Classifies runtime failures, locates root cause in the codebase, implements a targeted fix, runs tests, and redeploys. Full autonomous loop. No manual steps.
- ›Resolve a runtime crash or service failure without manual diagnosis
- ›Classify a failure type and trace root cause to the exact file and line
Feature Team
Spawn a 3-agent team (Backend Dev + Frontend Dev + QA) to implement features from PRDs. Agents own separate file territories and coordinate via messaging.
- ›Implement a full-stack feature from a PRD or task description
- ›Build a new page with backend API + frontend UI in parallel
Quality Team
Spawn a 3-agent QA gate (Test Writer + Code Reviewer + Coverage Analyst) for pre-release quality assurance and coverage remediation.
- ›Run a comprehensive QA gate before a major release
- ›Remediate test coverage gaps in an existing codebase
Security Team
Spawn a 3-agent security review team (Static Analyzer + Dependency Auditor + Threat Modeler) for pre-deploy security gates.
- ›Pre-deploy security gate before launching a new service
- ›Dependency audit for a third-party package adoption
Design Team
Spawn a 3-agent design team (UI Implementer + Accessibility Reviewer + Design System Enforcer) for building new pages, redesigns, and component work.
- ›Build a new page from a design reference or wireframe
- ›Redesign an existing page with design system enforcement
Frontend Design
Production-grade UI with a11y enforcement. Reads your design system, implements mobile-first components, audits WCAG AA compliance, and fixes every violation before the PR.
- ›Build a production-ready component from your design system with WCAG AA enforced
- ›Implement a responsive page from a design reference at 320px–1440px
Research Team
Spawn a 3-agent research team (Researcher + Strategist + Critic) for market research, competitive intelligence, and pre-PRD discovery.
- ›Market research before writing a PRD for a new feature
- ›Competitive intelligence on a rival product or category
Audit Swarm
Comprehensive multi-agent code audit. Dispatches domain-specialized agents in parallel, writes findings to structured reports, and creates tickets for P0/P1 issues.
- ›Weekly automated code audit across all your projects
- ›Pre-release security and quality gate
Audit Swarm Resolve
Resolve open audit findings by dispatching parallel fix agents. Reads audit reports, fixes P0→P1→P2 issues, runs tests, creates PRs, and updates audit docs.
- ›Clear the backlog of open audit findings across all projects
- ›Fix P0/P1 security or quality issues after an audit run
Repo Maintenance
Audit and clean up repositories: prune bloated CLAUDE.md files, find stub/empty tests, identify CI cost optimizations, and create PRs for all changes.
- ›Clean up a repo that has accumulated tech debt over time
- ›Prune an oversized CLAUDE.md to the 200-line limit
Incident Response
Structured production incident response: triage severity, contain the blast, create P0 ticket, gather evidence, run investigation, and generate post-mortem.
- ›Service is down and you need a structured response immediately
- ›Trading bot executing bad trades — halt and investigate
Onboard Repo
Full repository onboarding: security scan, generate CLAUDE.md, CI workflow, and lessons.md. Establishes quality gates and documents the codebase for agent use.
- ›Onboard a new repository with a complete agent constitution
- ›Bootstrap a fresh project with CI, CLAUDE.md, and quality gates
CI Wait and Merge
Block on CI, fix nits, auto-merge when green. Monitors your PR from push to merged — polls CI, classifies review comments, implements nits and minors autonomously, merges on green.
- ›Push a PR and come back to find it already merged
- ›Let an agent fix review nits while you work on something else
Debug Investigate
Scientific method debugging with a persistent eliminated-hypotheses log. Prevents the #1 AI debugging failure: re-testing disproven theories across context resets.
- ›Investigate a production bug with a structured methodology
- ›Resume a debugging session across context resets without repeating dead ends
Pressure Test
Stress-tests a feature idea against constraints, users, and your existing system in one pass. Verdict: kill or proceed with conditions. No building required.
- ›Kill a bad feature idea before writing a single line of code
- ›Stress-test a proposed addition against your existing system constraints
Learn
Captures what you learned from a session into lessons.md before the context window closes. Formats it as a structured entry — mistake, root cause, rule — so it compounds across sessions.
- ›Capture a debugging insight before you close the session
- ›Document a pattern that surprised you so it never surprises you again
PRD Writer
Idea to structured PRD in one command. Scope, requirements, measurable success criteria, and the open questions that will block engineering if you don't answer them first.
- ›Turn a Slack idea into a structured PRD before the first line of code
- ›Write explicit non-goals to kill scope creep before it starts
Context Budget
Audit your Claude context window usage. Ranks top consumers, scores each against value delivered, produces a trim list and runway estimate.
- ›Audit a long session before context saturation degrades response quality
- ›Identify which files and tool outputs are burning the most tokens
Deep Dive
Ad-hoc research from YouTube videos, URLs, or topics. Extracts knowledge, maps it to your ecosystem, and produces an integration plan.
