## What it does

The skill builds the source-side workspace that customize-* and build skills depend on: a git overlay tracker at `Linux_for_Tegra`, a `bsp_sources/` mono-tree (kernel, OOT, nvgpu, display, hwpm, hardware DTs) and a working NVIDIA Crosstool-NG prefix. It owns only the `source:` block in the active profile and the on-disk folder under `<source.root_path>`.

Here is the flow. It first refuses to run unless `<bsp_image.root_path>` already holds `Linux_for_Tegra/`, routing you back to `/jetson-init-image`. Then it creates or mounts the tracker, materializes `bsp_sources`, and resolves `source.toolchain`. For `bsp_sources` there are three branches in precedence order: an explicit `url:` in the profile, a local `public_sources.tbz2` from `<workspace>/Downloads`, and `source_sync.sh` as the fallback. The local archive is the preferred default because it skips NVIDIA git egress, which is the most common failure mode at this step. Setting both `url:` and `archive:` on one entry is rejected.

\`source.root_path` defaults to `<workspace>/Source` and is not written to the profile. The skill prompts only for an explicit custom path, unrelated content at the default location, or an unwritable parent. The `source_sync.sh` branch may produce per-component repos, but downstream builds still walk the canonical sub-paths under `bsp_sources/`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-source -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-source -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-source -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills jetson-init-source
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-source -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/jetson-init-source
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-source -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/NVIDIA/skills/tree/HEAD/skills/jetson-init-source/SKILL.md

## When to use it
- set up a Jetson BSP source workspace from scratch
- create the Linux_for_Tegra overlay tracker for later customizations
- get kernel and OOT sources into bsp_sources without NVIDIA git egress
- wire up a Crosstool-NG cross-compile prefix
- clone extra repos through source.repos

## Example prompts
- bootstrap the BSP source workspace for Jetson
- create the Linux_for_Tegra tracker and the bsp_sources tree
- point source.toolchain at my Crosstool-NG prefix

# Initialize BSP Customization Workspace

## Overview

This skill bootstraps the source-side workspace that customize-* / build
skills depend on: the `Linux_for_Tegra` overlay tracker (git repo for
pristine + customization commits), the `bsp_sources/` mono-tree (kernel,
OOT, nvgpu, display, hwpm, hardware DTs), and a working NVIDIA
Crosstool-NG cross-compile prefix. It owns only the `source:` block in
the active profile and the on-disk source workspace under
`<source.root_path>` (default: `<workspace>/Source`).

Responsibilities:

1. Optionally record a non-default `source.root_path`.
2. Create or mount the `Linux_for_Tegra` overlay tracker.
3. Materialize `bsp_sources` using the precedence in the "Materialize the BSP-sources baseline" step.
4. Resolve and record `source.toolchain`.
5. Clone extra user-defined repos from `source.repos:`.

## When to invoke

- The user asks to bootstrap, init, or sync the BSP customization
  workspace.
- A downstream customization skill refused with "no workspace
  tracker at `<source.root_path>/Linux_for_Tegra/`".
- After `jetson-init-image` (Setup's next step on a fresh target).

## Procedure

### Quick-start prefill mapping

Follow the shared
[`quick_start_prefill` contract](../../context/bsp-customization-workflow.md#quick_start_prefill-contract).
This skill has source-specific mappings:

- `quick_start_prefill.source.public_sources_archive` maps to the
  Branch-A archive candidate.
- `quick_start_prefill.source.repos` maps to proposed `source.repos:`
  entries; validate reserved keys and `url:` / `archive:` mutual
  exclusion before writing.
- `quick_start_prefill.source.toolchain` may be a cross-compile prefix,
  a `gcc` path, a containing `bin/` directory, an `x-tools.tbz2` archive
  path, or `skip`.

This skill remains the only owner of `source.root_path`, `source.repos:`,
and `source.toolchain` profile writes.

### Resolve the active target + paths

Resolve the active profile + workspace defaults per the contract in
