## What it does

The skill keeps a local mirror of your GitHub repositories under `~/projects/referenzen/` so the agent can check how something is already done in a sibling project. Helm chart layout, Kubernetes manifests, framework config, `docker-compose` conventions, CI/CD pipelines — instead of guessing, it opens the actual file and copies a proven pattern.

It works in steps. First it checks whether the repo is already cloned and runs `scripts/clone-or-update.sh owner/repo` if not. Then it asks which sibling project to use as reference, because scanning every repo blindly eats context. Search is targeted: `find` for the filename, then `grep` for the relevant section. When a pattern is adopted, the skill states the project and path it came from.

Reference projects are read-only. Only `git clone` and `git pull` write into that directory. There is also `scripts/list-workflow-triggers.sh`, which collects GitHub Actions triggers (`push`, `pull_request`, `schedule` and others) across all checkouts, sorts scheduled runs by weekday and time, and writes a report to `target/workflow-triggers.md`. A full `scripts/sync-all.sh` runs only on an explicit request, and it refuses to pull a repo with local changes — exit code 2 means skipped. Worth remembering if you edit files inside the mirror.

## Requirements
- Works with: GitHub, Docker, Kubernetes

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dboeckli/ai-agent-skills --skill project-references -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/project-references/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/project-references/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dboeckli/ai-agent-skills --skill project-references -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/project-references/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dboeckli/ai-agent-skills --skill project-references -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/project-references/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dboeckli/ai-agent-skills project-references
```

2. **Manually: put the files in place**
- File: `.github/skills/project-references/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dboeckli/ai-agent-skills --skill project-references -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dboeckli/ai-agent-skills --path .claude/skills/project-references
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/project-references/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dboeckli/ai-agent-skills --skill project-references -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dboeckli/ai-agent-skills/tree/HEAD/.claude/skills/project-references/SKILL.md

## When to use it
- reuse a Helm chart structure from a sibling project
- find a working database pool config
- match `docker-compose` conventions already used in your code
- get an overview of GitHub Actions triggers across repos
- clone or update a reference repo in one command

## Example prompts
- How should I structure the Helm chart for this project? Check the references.
- Clone my other-service as a reference.
- When do my projects run GitHub Actions — push, PR, or schedule?

description: "Look up conventions, patterns, and concrete implementations from your own GitHub repositories checked out locally under ~/projects/referenzen/. Use this skill whenever there is uncertainty about how something is done in your codebase family — e.g. Helm chart structure, Kubernetes manifests, framework configuration patterns, Docker Compose conventions, CI/CD pipeline setup, or any other recurring architectural decision. Invoke it proactively before guessing at a convention; always cite the source project and path when a pattern is adopted. Also use when the user asks to check out, update, or search reference repositories, or to generate an overview/report of GitHub Actions triggers (push, pull_request, schedule/cron) across repositories."

# Project References

This skill manages a local mirror of your own GitHub repositories under
`~/projects/referenzen/` and lets you look up conventions and implementation
patterns without guessing or reading all repos blindly.

All operations are **read-only** on the reference projects themselves. Only
`git clone` and `git pull` write into that directory — never edits.

---

## Instructions

### Step 1: Check whether the relevant repo is already cloned

```bash
ls ~/projects/referenzen/
```

If the needed repo is missing, run `scripts/clone-or-update.sh owner/repo` to clone it first.

### Step 2: Ask the user which reference project is most relevant

Do not scan all repos blindly — that fills context. Ask: "Which of your sibling projects uses this pattern?" or list the available repos and let the user pick.

### Step 3: Search targeted — file first, then grep

Use `find` to locate a file by name, then `cat` or `grep` to read only the relevant section. For search commands and patterns, consult `references/search-patterns.md`.

### Step 4: Cite the source when adopting a pattern

Always state which project and file path a pattern came from before applying it:

> Pattern adopted from `your-service` → `helm-charts/Chart.yaml` line 4

### Step 5: Sync only when explicitly requested

Run `scripts/sync-all.sh` only when the user says "sync all" or "update all references". For a single repo, prefer `scripts/clone-or-update.sh`.
