Step 1 — Parse Arguments

Read $ARGUMENTS and extract project_name (the first word/token).

• If $ARGUMENTS is empty or missing, stop and ask the user: "Please provide a project name, e.g. /cpp-cookiecutter myproject."

---

Step 2 — Verify Working Directory

Run pwd and git rev-parse --show-toplevel 2>/dev/null.

• If the git root differs from pwd, warn the user and stop. All paths must be relative to the repo root.

---

Step 3 — Create Directories

Run:

mkdir -p src test bin

All three directories are created with -p (no error if already present).

---

Step 4 — Create CMakeLists.txt (root)

Use Glob to check whether CMakeLists.txt already exists.

Only if it does not exist, use the Write tool to create CMakeLists.txt with this exact content, replacing <project_name> with the value from Step 1:

cmake_minimum_required(VERSION 3.14)
project(<project_name>)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
enable_testing()
add_subdirectory(src)
add_subdirectory(test)

---

Step 5 — Create src/CMakeLists.txt

Use Glob to check whether src/CMakeLists.txt already exists.

Only if it does not exist, use the Write tool to create src/CMakeLists.txt with this exact content, replacing <project_name> with the value from Step 1:

# add_library(<project_name> STATIC
#   <project_name>.cpp
# )
# target_include_directories(<project_name> PUBLIC ${CMAKE_SOURCE_DIR}/src)

---

Step 6 — Create test/CMakeLists.txt

Use Glob to check whether test/CMakeLists.txt already exists.

Only if it does not exist, use the Write tool to create test/CMakeLists.txt with this exact content, replacing <project_name> with the value from Step 1:

include(FetchContent)
FetchContent_Declare(
  googletest
  URL https://github.com/google/googletest/archive/refs/tags/v1.14.0.zip
)
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)

# add_executable(<project_name>_test <project_name>_test.cpp)
# target_link_libraries(<project_name>_test GTest::gtest_main)
# add_test(NAME <project_name>_test COMMAND <project_name>_test)

---

Step 7 — Create src/<project_name>.cpp

Use Glob to check whether src/<project_name>.cpp already exists (substitute the actual project name).

Only if it does not exist, use the Write tool to create src/<project_name>.cpp with this exact content:

// <project_name> source

---

Step 8 — Create test/<project_name>_test.cpp

Use Glob to check whether test/<project_name>_test.cpp already exists (substitute the actual project name).

Only if it does not exist, use the Write tool to create test/<project_name>_test.cpp with this exact content, replacing <project_name> with the value from Step 1:

#include <gtest/gtest.h>
TEST(<project_name>, Placeholder) { EXPECT_TRUE(true); }

---

Step 9 — Report

Print a summary listing each item and whether it was created or skipped (already exists):

• src/ — created (always, idempotent with -p)
• test/ — created (always, idempotent with -p)
• bin/ — created (always, idempotent with -p)
• CMakeLists.txt: created or skipped (already exists)
• src/CMakeLists.txt: created or skipped (already exists)
• test/CMakeLists.txt: created or skipped (already exists)
• src/<project_name>.cpp: created or skipped (already exists)
• test/<project_name>_test.cpp: created or skipped (already exists)

---

Final Step — Record Usage

After the skill's primary task completes, run:

python3 ${PWD}/.claude/skills/skill-stat/scripts/record-stat.py "cpp-cookiecutter"
