Purpose

This project provides a collection of 25 pre-packaged, text-based instruction sets (skills) for AI coding agents. It focuses heavily on DevOps, infrastructure automation, security, and software engineering tasks.

Security Assessment

Overall risk: Medium. The tool is inherently designed to execute shell commands, interact with infrastructure, and perform security audits, meaning an AI agent acting on these instructions could make significant changes to your system. Additionally, the automated installation script (`install.sh`) contains a `rm -rf` recursive force deletion command, which is a common vector for accidental data loss if the script fails or is improperly scoped. No hardcoded secrets or dangerous network requests were identified in the static scan, and no elevated system permissions are explicitly requested beyond standard user execution.

Quality Assessment

The repository is actively maintained (last push was today) and is properly licensed under the permissive MIT license. However, community trust and visibility are currently very low. The project only has 5 GitHub stars, meaning it has not been broadly vetted by the open-source community. Because this is designed to guide automated agents in complex infrastructure tasks, the lack of extensive peer review is a notable concern.

Verdict

Use with caution. The MIT license and active maintenance are positives, but the unvetted low community visibility and the presence of recursive deletion commands in the installer mean you should carefully review the specific skill instructions before allowing any AI agent to execute them on your system.

Compatibility

These skills follow the Agent Skills open standard -- the cross-vendor format for portable AI agent capabilities. Any tool that reads SKILL.md files can use them directly:

  • Claude Code -- native support
  • OpenAI Codex CLI -- native support
  • Gemini CLI -- native support
  • Cursor -- native support
  • VS Code GitHub Copilot -- native support
  • Windsurf -- native support
  • OpenCode -- native support
  • Cline -- native support

  • Any other tool that implements the Agent Skills spec

No conversion, no adapters. Drop the skill folder in your tool's skills directory and it works.

Why these skills

These aren't generic prompts copy-pasted from a blog post. Every skill in this collection has been built iteratively, analyzed against real-world usage, cross-checked with official documentation, and refined through multiple passes until it actually works the way you'd expect. Each one is structured with a compact core that triggers fast and loads clean, plus dedicated reference files that get pulled in only when the agent needs the deep stuff -- compliance checklists, manifest templates, pattern libraries. No bloat in the main body, no missing context when it matters.

Every skill is researched well beyond any model's training cutoff. We're talking current CVEs, recent breaking changes, deprecation notices, and gotchas from this week -- not whatever the model last saw during pre-training. When Kubernetes drops a beta API, when Terraform changes provider behavior, when Docker deprecates a build flag -- these skills already know about it. Models are smart, but their knowledge has a shelf life. These skills keep it current.

This is a growing collection. New skills get added as they're built, tested, and proven useful. If you're using an AI coding tool without custom skills, you're leaving a lot of capability on the table.

NEW: Self-Improving Skills

skill-refiner brings Karpathy's AutoResearch pattern to AI skill collections. Instead of manually reviewing and improving skills one by one, skill-refiner runs an automated loop that scores, improves, and validates every skill in the collection -- then does it again.

The loop: Score -> Improve -> Verify -> Keep or Revert -> Repeat.

  • Adaptive focus -- first pass scores everything, then subsequent iterations zero in on the weakest skills until they're brought up to standard
  • Three-layer evaluation -- lint validation (structural), AI self-check (quality), and behavioral testing against synthetic tasks (does the skill actually work?)
  • Cross-model peer review -- if you have multiple AI harnesses installed (Claude + Codex, for example), the secondary model reviews every improvement the primary makes. Adversarial evaluation catches single-model blind spots.
  • Karpathy gate -- only changes that measurably improve a skill's score survive. Everything else gets reverted. No drift, no degeneration, monotonic improvement.
  • Self-improvement -- skill-refiner improves its own evaluation infrastructure (including itself) in a separate meta-phase with human review checkpoints

10 iterations. 25 skills. One command.

How they're built

Each skill follows the Agent Skills specification:

  • SKILL.md with YAML frontmatter -- name, description, license, optional compatibility for environment requirements, and metadata for custom fields. The frontmatter is what agents read at startup to decide which skills to activate.
  • Compact body (target under 500 lines, 600 hard max) -- the core instructions that load into every conversation. Kept lean so it doesn't eat your context window.
  • Reference files (references/ directory) -- detailed pattern libraries, compliance checklists, manifest templates. The agent reads these on-demand when the task requires depth. You get expert-level detail without paying the token cost upfront.
  • Argument hints (metadata.argument_hint) -- tells agents what arguments a skill expects when invoked (e.g., <file-or-pattern>, [iterations]). Angle brackets for required, square brackets for optional.
  • Precise trigger descriptions -- optimized so the right tool activates the right skill at the right time. Every trigger keyword is tested and tuned to minimize false positives and missed activations.
  • Cross-skill awareness -- skills know about each other. The security-audit skill knows not to step on lockpick's territory. Docker knows to defer to Kubernetes for cluster networking. No overlapping, no conflicts.

Install

Quick install (via skills.sh)

# All skills
npx skills add iuliandita/skills

# Pick specific ones
npx skills add iuliandita/skills --skill kubernetes --skill docker --skill terraform

# See what's available
npx skills add iuliandita/skills --list

Using the bundled installer

# All skills for Claude (default)
git clone https://github.com/iuliandita/skills.git /tmp/skills-install
/tmp/skills-install/install.sh
rm -rf /tmp/skills-install

# Install for a specific tool
git clone https://github.com/iuliandita/skills.git /tmp/skills-install
/tmp/skills-install/install.sh --tool codex
rm -rf /tmp/skills-install

# Pick and choose
git clone https://github.com/iuliandita/skills.git /tmp/skills-install
/tmp/skills-install/install.sh --tool claude kubernetes docker terraform ansible
/tmp/skills-install/install.sh --list  # see what's available
rm -rf /tmp/skills-install

Multi-tool install with symlinks

Install once, symlink everywhere. Skills go to a single canonical directory (~/.agents/skills/), and each tool gets symlinks. Update the canonical copy and all tools see the change.

git clone https://github.com/iuliandita/skills.git /tmp/skills-install

# Install for Claude, Cursor, and Gemini in one shot
/tmp/skills-install/install.sh --tool claude,cursor,gemini --link

# Check for updates later
/tmp/skills-install/install.sh --check --link

rm -rf /tmp/skills-install

Override the canonical directory with SKILLS_CANONICAL_DIR:

SKILLS_CANONICAL_DIR=~/my-skills ./install.sh --tool claude,roo --link

Checking for updates

Each install writes a .skills-lock.json with content hashes. Compare against the source to see what changed:

./install.sh --check                # check default (Claude)
./install.sh --check --tool cursor  # check a specific tool
./install.sh --check --link         # check canonical dir

Manual

cp -r skills/kubernetes ~/.claude/skills/kubernetes
cp -r skills/kubernetes ~/.codex/skills/kubernetes
cp -r skills/kubernetes ~/.cursor/skills/kubernetes

Requirements

Any AI coding tool that supports the Agent Skills standard. See the supported tools table above for the full list of tested targets.

Updating

Pull the latest and re-run the installer:

cd /path/to/skills
git pull
./install.sh --force

Or check what changed first:

cd /path/to/skills
git pull
./install.sh --check   # see what's outdated
./install.sh --force   # update everything

The installer backs up existing skills before overwriting (unless --no-backup), so you won't lose local customizations.
