Context Mixer
Three command-line tools that manage the lifecycle of curated agentic context
— agents, skills, and the engineering intents behind them — across AI coding
assistants.
| Tool | Role |
|---|
| cmx | Package manager: installs, versions, updates, and reconciles agents and skills across Claude Code, Copilot, Cursor, Codex, and a dozen other platforms |
| cmf | Context Mixer Forge: compiles a profile-specific slice of an intent atlas into an installed agent or skill, and records what it compiled |
| cmv | Context Mixer Verify: checks, deterministically, that a repository holds the intents cmf compiled for it |
The intent atlas is the externally maintained knowledge base cmf and cmv
work from: the ecosystems it supports and how to sense them, structured intent
records in and around those ecosystems, and the validators beside them. The
reference atlas is svetzal/guidelines;
fork it or replace it, and the tooling works the same way.
Documentation
The book at https://vetzal.ca/context-mixer2/ covers installation,
the user guide, writing agents, skills, and intents, the command references for
all three tools, and the design documents.
Install
brew install svetzal/tap/cmx
installs all three binaries (cmv from release 3.2.0). From a checkout,
./install.sh builds and installs them with cargo install.
Repository
cmx/, cmf/, cmv/ — the three binariescmx-core/ — the embeddable core library, published to crates.io and twinned
with the TypeScript port in cmx-core-ts/intent-atlas/ — the shared reader of an intent atlas that cmf and cmv usebook/ — the mdBook source for the documentation sitereference-atlas/ — the owned contract corpus, source cases and golden regressionsbenchmark/ — assembly benchmarks and behavioural exercises for cmf and cmv
CHARTER.md states the project's purpose and non-goals; AGENTS.md holds the
quality gates, release process, and architecture map for contributors and
coding agents.
