+# Setup Shared Remote Executor
+
+Skill for setting up Claude Code's shared remote executor in new projects.
+
+## When to Use
+- When adding Claude Code support to a new project
+- When the user says "set up remote executor for this project"
+- When working on a new project that needs remote command execution
+
+## Prerequisites
+- Shared executor already deployed at `~/.claude/` on wizard@10.0.10.10
+- Project accessible via NFS from both macOS and the remote VM
+
+## Setup Steps
+
+### 1. Create .claude Directory
+```bash
+mkdir -p .claude/sessions
+```
+
+### 2. Create session-exec.sh Wrapper
+Create `.claude/session-exec.sh` with the following content (adjust PROJECT_ROOT):
+
+```bash
+#!/bin/bash
+# Project-Local Session Helper - Wrapper for shared executor
+
+set -euo pipefail
+
+SHARED_SESSION_EXEC="/home/wizard/.claude/session-exec.sh"
+PROJECT_ROOT="/home/wizard/path/to/project"  # UPDATE THIS
+
+if [ -f "$SHARED_SESSION_EXEC" ]; then
+    if [ "${1:-}" = "create" ] || [ -z "${1:-}" ]; then
+        "$SHARED_SESSION_EXEC" create "$PROJECT_ROOT"
+    else
+        "$SHARED_SESSION_EXEC" "$@"
+    fi
+else
+    SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+    SESSIONS_DIR="$SCRIPT_DIR/sessions"
+    SESSION_ID="${1:-$(date +%s)-$$-$RANDOM}"
+    ACTION="${2:-create}"
+    SESSION_DIR="$SESSIONS_DIR/$SESSION_ID"
+
+    case "$ACTION" in
+        create|init|"")
+            mkdir -p "$SESSION_DIR"
+            echo "ready" > "$SESSION_DIR/cmd_status.txt"
+            echo "$PROJECT_ROOT" > "$SESSION_DIR/workdir.txt"
+            > "$SESSION_DIR/cmd_input.txt"
+            > "$SESSION_DIR/cmd_output.txt"
+            echo "$SESSION_ID"
+            ;;
+        cleanup|remove|delete)
+            [ -d "$SESSION_DIR" ] && rm -rf "$SESSION_DIR"
+            ;;
+        status)
+            [ -d "$SESSION_DIR" ] && cat "$SESSION_DIR/cmd_status.txt"
+            ;;
+        list)
+            [ -d "$SESSIONS_DIR" ] && ls -1 "$SESSIONS_DIR" 2>/dev/null
+            ;;
+    esac
+fi
+```
+
+Make executable: `chmod +x .claude/session-exec.sh`
+
+### 3. Link Sessions Directory (on remote VM)
+Run on the remote VM to add project sessions to the shared executor:
+
+```bash
+# Option A: Symlink project sessions (if using project-local sessions)
+ln -sfn /path/to/project/.claude/sessions ~/.claude/sessions
+
+# Option B: Use shared sessions (all projects share one directory)
+# Just ensure ~/.claude/sessions exists
+```
+
+### 4. Create CLAUDE.md
+Add execution instructions to `.claude/CLAUDE.md`:
+
+```markdown
+## Remote Command Execution
+Uses shared executor at `~/.claude/` on wizard@10.0.10.10.
+
+### Usage
+\```bash
+SESSION_ID=$(.claude/session-exec.sh)
+echo "command" > .claude/sessions/$SESSION_ID/cmd_input.txt
+sleep 1 && cat .claude/sessions/$SESSION_ID/cmd_status.txt
+cat .claude/sessions/$SESSION_ID/cmd_output.txt
+\```
+
+Start executor: `~/.claude/remote-executor.sh` (on remote VM)
+```
+
+## Shared Executor Location
+- Scripts: `~/.claude/remote-executor.sh`, `~/.claude/session-exec.sh`
+- Sessions: `~/.claude/sessions/`
+- Remote VM: wizard@10.0.10.10
