Rýni

A linter for your agent harness.

Documentation

Harness engineering is hard. Keeping a team aligned on it is harder. Rýni checks your AGENTS.md, instructions, skills, and Markdown docs against shared conventions, so your agents get a consistent and coherent working environment.

  • 🔍 Lint your harness. Catch structural issues with deterministic checks.
  • 📝 Review your markdown docs. Structure non-deterministic checks that require judgment.
  • 📦 Share your conventions. Turn your team’s standards into rule packs you can use across repositories.

Get started

Requires Python 3.14 or later. Add Rýni and tidy-harness, an opinionated example rule pack, as development dependencies:

uv add --dev ryni tidy-harness
uv run ryni check .

Installed rules are active automatically. The CLI runs deterministic checks and reports agent reviews as pending. Commit pyproject.toml and uv.lock to share the same versions with your team.

Run with your agent

Install the bundled skill for your agent, then invoke it in the same repository:

Agent Install in your terminal Send in your agent
Claude Code uv run ryni skill install .claude/skills /ryni-check
Codex uv run ryni skill install .agents/skills $ryni-check

The skill runs deterministic checks, delegates reviews to sub-agents, and combines the findings. Your agent must support sub-agents to complete reviews. Rýni itself runs no model and needs no API key.

Make it your own

A rule pack can combine deterministic checks with instructions for agent reviews. Write your team's conventions once and share them across repositories.
