Claude Code plugins, built from first principles.
Axiom is a curated marketplace of plugins for Claude Code - solid ground for whatever you're building.
Every plugin in Axiom earns its place. Before anything ships, it's measured against real task scenarios with graded, repeatable evals - so what you install is backed by empirical data, not good intentions. No toys, no vibe-coded filler, no tokens burned on output that doesn't move the needle. If it can't be measured, it doesn't ship.
Want receipts? Each plugin keeps a scored eval history in its own README, and the index below is generated so new plugin evals surface here automatically.
The eval index is generated from .claude-plugin/marketplace.json and each
shipped skill's evals/evals.json manifest. Plugin READMEs are the canonical
scored histories.
| Plugin | Evaluated skill manifests | Scenarios | Manifest expectations | Scored history |
|---|---|---|---|---|
| axiom-git | commit-message | 6 | 24 | Eval history |
| axiom-versioning | dependency-versions | 5 | 25 | Eval history |
Current coverage: 2 plugins, 2 evaluated skills, 11 scenarios, 49 manifest expectations.
/plugin marketplace add netopsengineer/axiomPlugin sources in this marketplace use relative paths, which resolve only when
the marketplace is added from a Git host (GitHub, GitLab, or a git URL) - not
from a direct URL to marketplace.json.
Composes Conventional Commits messages with gitmoji from the staged diff, with safety gates for protected branches, staged secrets, and pre-commit hooks.
