Ccx — Development skill for Claude Code

ccx

[](https://github.com/aneveux/ccx/actions/workflows/ci.yml) [](https://github.com/aneveux/ccx/releases/latest) [](LICENSE)

CLI for managing fine-grained Claude Code configuration per project. Handles `CLAUDE.md` composition, plugin enablement, MCP servers, skill overrides, and rules — without manually juggling files.

Install

**Linux x86_64 — one line (no sudo required):**

curl -fsSL https://raw.githubusercontent.com/aneveux/ccx/master/install.sh | bash

The installer drops the `ccx` binary into `~/.local/bin` by default. Make sure that directory is on your `$PATH`:

export PATH="$HOME/.local/bin:$PATH"   # add to ~/.bashrc or ~/.zshrc

Override the install directory with `CCX_INSTALL_DIR`:

CCX_INSTALL_DIR=/usr/local/bin curl -fsSL https://raw.githubusercontent.com/aneveux/ccx/master/install.sh | bash

The installer downloads the latest Linux x86_64 binary, **verifies its SHA-256 checksum before installing (fail-closed — it aborts on a missing or mismatched checksum)**, then moves the binary into the install directory. Set `CCX_SKIP_CHECKSUM=1` only if you understand the risk.

Or download a binary directly from [Releases](https://github.com/aneveux/ccx/releases/latest).

Quick start

ccx ships no profiles in the binary — author your own with:

ccx profiles new my-profile
ccx profiles enable my-profile
