Reads an unfamiliar repository and writes a starting ledger, so the agent knows the layout from the first session.

## What it does

The skill spawns a subagent called `onboard`. It makes the directories `thoughts/shared/handoffs/<project-name>` and `.claude`, then walks the code. Its first attempt is `tldr tree . && tldr structure .`; without those tools it falls back to a `find` over `*.py`, `*.ts` and `*.js` files. Stack detection looks for `package.json`, `requirements.txt`, `Cargo.toml`, `go.mod`. Before writing anything it asks what you want to achieve, through AskUserQuestion.

The result is a YAML handoff at `thoughts/shared/handoffs/<project-name>/onboard-<date>.yaml`. It holds the date, your stated goal, the detected stack, important files with their purpose, a short architecture note and a suggested first action. Session start loads that file on its own, which is why the agent stops asking the same questions. Exploration happens in the subagent, so code dumps stay out of your main context.

This one targets brownfield work. On an empty repository there is nothing to map, and `/create_plan` covers that case. The ledger is not frozen: `/create_handoff` rewrites it later. Install runs through `npx skills add`, or `gh skill install` on GitHub Copilot.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill onboard -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill onboard -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill onboard -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 onboard
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill onboard -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/onboard
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill onboard -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/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/onboard/SKILL.md

## When to use it
- get oriented in an unfamiliar repository before touching code
- record the stack and important files in one place
- hand the agent starting context without retelling the architecture
- keep codebase dumps out of the main session
- pick a first action for the task at hand

## Example prompts
- Onboard me to this project at $CLAUDE_PROJECT_DIR
- Analyze this codebase and create the initial continuity ledger
- Explore the repo, detect the tech stack and suggest where to start

# Onboard - Project Discovery & Ledger Creation

Analyze a brownfield codebase and create an initial continuity ledger.

## When to Use

- First time working in an existing project
- User says "onboard", "analyze this project", "get familiar with codebase"

## How to Use

**Spawn the onboard agent:**

Use the Task tool with `subagent_type: "onboard"` and this prompt:

```
Onboard me to this project at $CLAUDE_PROJECT_DIR.

1. Create required directories if they don't exist:
   mkdir -p thoughts/shared/handoffs/<project-name> .claude

2. Explore the codebase using available tools:
   - Try: tldr tree . && tldr structure .
   - Fallback: find . -type f -name "*.py" -o -name "*.ts" -o -name "*.js" | head -50

3. Detect tech stack (look for package.json, requirements.txt, Cargo.toml, go.mod, etc.)

4. Ask the user about their goals using AskUserQuestion

5. Create a YAML handoff at thoughts/shared/handoffs/<project-name>/onboard-<date>.yaml:
   ---
   date: <ISO date>
   type: onboard
   status: active
   ---
   goal: <user's stated goal>
   now: Start working on <first priority>
   tech_stack: [list of detected technologies]
   key_files:
     - path: <important file>
       purpose: <what it does>
   architecture: <brief description>
   next:
     - <suggested first action>
```

## Why an Agent?

The onboard process:
- Requires multiple exploration steps
- Should not pollute main context with codebase dumps
- Returns a clean summary + creates the handoff

## Output

- Directories created: `thoughts/shared/handoffs/<project>/`, `.claude/`
- YAML handoff created (loaded automatically on session start)
- User has clear starting context
- Ready to begin work with full project awareness

## Notes

- This skill is for BROWNFIELD projects (existing code)
- For greenfield, use `/create_plan` instead
- Handoff can be updated anytime with `/create_handoff`
