Code Virtuoso
AI agent skill sets for software engineering — built on the Agent Skills open standard. Knowledge, Tools, Frameworks, Playbooks, Roles, and Agents.
Six categories, installable independently or as bundles:
- Knowledge — Design Patterns, Refactoring, SOLID Principles, Debugging, Clean Architecture, Testing, API Design, Security, Scrum, Performance, Microservices, Git Workflow, CI/CD, Accessibility, Database Design. Reference material with progressive disclosure.
- Tools — Agentic Rules Writer. Agent configuration and bootstrapping tools.
- Frameworks — Symfony Components, Symfony Upgrade, Django Components, LangChain Components. Component-level reference and version upgrade guides for framework-specific development.
- Playbooks — PHP Upgrade, Composer Dependencies. Step-by-step operational procedures for recurring maintenance tasks.
- Roles — Product Manager, Architect, Backend Dev, Frontend Dev, QA Engineer, Project Manager. Reference skills defining responsibilities, workflows, and handoff checklists for each team role.
- Agents — 15 sub-agent definitions (8 specialist + 7 role agents) following the Claude Code sub-agents standard. Specialist agents handle focused tasks (investigation, TDD, code review, refactoring, auditing, documentation, migration planning, test gap analysis). Role agents embody team positions with persistent memory and skill preloading.

Auto-update (once daily, background)
macOS / Linux — runs silently on each new shell, at most once per day:
echo '_skills_marker="${TMPDIR:-/tmp}/.skills-updated-$(date +%Y%m%d)"
[ ! -f "$_skills_marker" ] && (npx skills update --yes >/dev/null 2>&1 && touch "$_skills_marker" &)' >> ~/.zshrc
Windows (PowerShell) — same behavior, once per day on shell startup:
Add-Content $PROFILE '$marker = "$env:TEMP\.skills-updated-$(Get-Date -Format yyyyMMdd)"; if (-not (Test-Path $marker)) { Start-Job { npx skills update --yes *> $null; New-Item $using:marker -Force } | Out-Null }'
Project-level — auto-update after every git pull via post-merge hook:
printf '#!/bin/sh\nnpx skills update --yes >/dev/null 2>&1 &\n' > .git/hooks/post-merge && chmod +x .git/hooks/post-merge
