+# SBo Submission Archive Hook — Design Spec
+
+**Date:** 2026-03-31
+
+---
+
+## Goal
+
+A `post-commit` git hook that automatically offers to create a SBo-ready submission
+archive whenever a package's `.SlackBuild` file is added or modified in a commit.
+
+---
+
+## Detection
+
+Uses `git diff-tree --no-commit-id -r --name-status HEAD` to list files changed in
+the current commit. Filters for entries with status `A` (added) or `M` (modified)
+whose filename matches `*.SlackBuild` at exactly one directory depth
+(e.g. `hugo/hugo.SlackBuild`). Each match yields one package name (the parent directory).
+
+Multiple packages in a single commit are handled sequentially.
+
+---
+
+## Per-Package Flow
+
+1. Print header: `==> Package: <name>`
+2. List all files inside `<repo-root>/<pkg>/` recursively, shown as relative paths
+3. Prompt: `Create SBo archive for '<pkg>'? [y/N]`
+   - Input is read from `/dev/tty` so the prompt works correctly inside a git hook
+4. On `y`/`Y`: create the archive (see below)
+5. On anything else: skip silently and continue to the next package
+
+---
+
+## Archive
+
+- **Location:** `SBo/<pkg>.tar.gz` (inside repo root, not under version control)
+- **Structure:** single top-level directory `<pkg>/` containing all package files flat
+- **Command:** `tar -czf "$SBO_DIR/$pkg.tar.gz" -C "$REPO_ROOT" "$pkg"`
+- `SBo/` is created automatically if it does not exist
+- Repeated archives overwrite the previous one (no version suffix — matches SBo naming conventions)
+
+---
+
+## Output Directory
+
+`SBo/` lives at the repo root and is added to `.gitignore` so it is never committed.
+
+---
+
+## Files Changed
+
+| File | Change |
+|---|---|
+| `.git/hooks/post-commit` | New file (created, made executable) |
+| `.gitignore` | Append `SBo/` entry |
+
+---
+
+## Out of Scope
+
+- Verifying checksums or linting (handled by existing pre-commit hook and manual workflow)
+- Uploading or submitting to SBo directly
+- Tracking which archives have already been submitted
