-description: Merge a worktree branch back into the base branch
+description: Merge worktree changes and clean up safely
 ---
-Merge a branch from the worktree.
-If you're currently working on a worktree, assume that's the one I'm referring to.
 
-Start by committing any staged and unstaged changes. I may have made changes to the worktree manually.
-Then merge back the new main branch, since I may have made changes to it.
+# Merge Worktree and Cleanup
 
-# Language specific:
+Merge changes from the current worktree into a target branch and clean up the worktree.
 
-## Rust
+**Usage:** `/merge [target-branch]`
 
-Ensure cargo check is happy.
-Ensure clippy is happy. clean up any new warnings.
+**Arguments:**
+- `$1`: Target branch to merge into (default: auto-detect main/master)
 
-## Typescript
+## Process
 
-Ensure tsc is happy.
+### 1. Pre-flight Checks
 
-# Finally
+```bash
+CURRENT_BRANCH=$(git branch --show-current)
+WORKTREE_DIR=$(git rev-parse --git-common-dir)
 
-Squash the commits into a single one, merge into the base branch, and delete the worktree.
+if [[ ! "$WORKTREE_DIR" == *".git/worktrees"* ]]; then
+  echo "❌ Error: You're not in a worktree"
+  exit 1
+fi
+
+if ! git diff-index --quiet HEAD --; then
+  echo "❌ Error: You have uncommitted changes"
+  git status --short
+  exit 1
+fi
+```
+
+### 2. Determine Target Branch
+
+```bash
+TARGET_BRANCH="${1:-}"
+if [ -z "$TARGET_BRANCH" ]; then
+  if git show-ref --verify --quiet refs/heads/main; then
+    TARGET_BRANCH="main"
+  elif git show-ref --verify --quiet refs/heads/master; then
+    TARGET_BRANCH="master"
+  else
+    echo "❌ Error: Cannot auto-detect main branch"
+    exit 1
+  fi
+fi
+```
+
+### 3. Update Target Branch
+
+```bash
+WORKTREE_PATH=$(pwd)
+COMMON_DIR=$(git rev-parse --git-common-dir)
+REPO_ROOT=$(echo "$COMMON_DIR" | sed 's/\.git.*//' | sed 's/\/$//')
+if [ "$COMMON_DIR" = ".git" ]; then
+  REPO_ROOT=$(git rev-parse --show-toplevel)
+fi
+
+cd "$REPO_ROOT"
+git checkout "$TARGET_BRANCH"
+git pull origin "$TARGET_BRANCH"
+```
+
+### 4. Merge
+
+```bash
+git merge --no-ff "$CURRENT_BRANCH" -m "Merge branch '$CURRENT_BRANCH'"
+```
+
+If you prefer a squash merge, do this instead:
+
+```bash
+git merge --squash "$CURRENT_BRANCH"
+git commit -m "feat: <summary>"
+```
+
+### 5. Push and Clean Up
+
+```bash
+git push origin "$TARGET_BRANCH"
+
+git worktree remove "$WORKTREE_PATH" --force || rm -rf "$WORKTREE_PATH"
+git branch -d "$CURRENT_BRANCH" || git branch -D "$CURRENT_BRANCH"
+```
+
+### 6. Optional: Delete Remote Branch
+
+```bash
+git push origin --delete "$CURRENT_BRANCH"
+```
+
+## Language-specific checks
+
+### Rust
+- `cargo check`
+- `cargo clippy` (clean up new warnings)
+
+### TypeScript
+- `tsc`

-description: Start a new feature in a git worktree
+description: Start parallel work on a feature using git worktree
 ---
-In a worktrees directory inside the git project's root, create a new worktree for the requested feature.
-create the directory if it doesn't exist.
-keep the branch name concise, and don't include "opencode" in its name.
-do all the work for the feature in the new worktree.
-run "kitty @ set-tab-title" to set the tab title of this kitty session to "<project>/<feature>"
+
+# Start Worktree for Feature
+
+Initialize a new git worktree to work on a feature in parallel with your current work.
+
+**Usage:** `/work "feature description"`
+**Manual:** `/work branch-name`
+
+**Arguments:**
+- `$1`: Feature description (quoted) OR branch name (single word)
+
+## Requirements
+
+- Must run from the main repository (not inside an existing worktree)
+- Git installed, repository clean or stashable
+- Worktrees live in `worktrees/` inside the repo root
+
+## Process
+
+### 1. Pre-flight Checks
+
+```bash
+# Ensure we're in a git repo
+git rev-parse --git-dir > /dev/null
+
+# Ensure not already in a worktree
+CURRENT_GIT_DIR=$(git rev-parse --git-common-dir)
+if [[ "$CURRENT_GIT_DIR" == *".git/worktrees"* ]]; then
+  echo "❌ Error: already inside a worktree"
+  exit 1
+fi
+
+# Ensure clean (or stash)
+if ! git diff-index --quiet HEAD --; then
+  echo "⚠️  Working tree has changes"
+  git status --short
+  echo "Stash before creating worktree"
+  git stash push -m "Auto-stash before worktree"
+fi
+```
+
+### 2. Determine Base Branch
+
+```bash
+if git show-ref --verify --quiet refs/heads/main; then
+  BASE_BRANCH="main"
+elif git show-ref --verify --quiet refs/heads/master; then
+  BASE_BRANCH="master"
+else
+  echo "❌ Error: Cannot auto-detect base branch"
+  exit 1
+fi
+```
+
+### 3. Determine Branch Name
+
+If `$1` contains spaces, treat it as a description and generate a concise branch name.
+
+Rules:
+- Lowercase, hyphens, max 50 chars
+- Prefer `feat/`, `fix/`, `refactor/`, `chore/` prefixes when obvious
+
+If `$1` is a single word, use it directly.
+
+**Do not include "opencode" in the branch name.**
+
+### 4. Create Worktree
+
+```bash
+REPO_ROOT=$(git rev-parse --show-toplevel)
+WORKTREES_DIR="$REPO_ROOT/worktrees"
+mkdir -p "$WORKTREES_DIR"
+
+WORKTREE_PATH="$WORKTREES_DIR/$BRANCH_NAME"
+git worktree add -b "$BRANCH_NAME" "$WORKTREE_PATH" "$BASE_BRANCH"
+```
+
+### 5. Next Steps
+
+```bash
+cd "$WORKTREE_PATH"
+git status
+```
+
+## Notes
+
+- Use `/worktree-compare` to review changes before merging.
+- Use `/merge` when ready to integrate.
