#yaml

Fast and well tested serialization library

A strongly typed, comment-supporting YAML deserializer that deserializes YAML directly into your Rust types without constructing an intermediate tree of “abstract values.”

:blue_book: dict subclass with keylist/keypath support, built-in I/O operations (base64, csv, html, ini, json, pickle, plist, query-string, toml, xls, xml, yaml), s3 support and many utilities.

Link Modeling Language (LinkML) model

The context every AI coding agent reads — authors AGENTS.md, CLAUDE.md, GEMINI.md & .cursorrules from your repo's real stack. IANA-registered .faf format.

🌱 + 👀 Provides a composer package with a Twig loader for files with YAML front-matter.

Making linters play nice... Mostly.

Operations substrate for AI agents that use real software: 311 sites/tools, logged-in browsers, desktop apps, local tools, MCP, policy, evidence, AgentEnvelope v2, and self-repair.

AI agent governance for teams. Runtime firewalls tell you what happened; Conduct Guard controls what can happen — signed policy, verified chain, fail-closed by default. Ships with Router (LLM proxy), 20+ compliance packs, canvas UI, and a playbook engine.

Complete AI development workflow for 19+ tools. Builtin rules, agents, and conventions out of the box. Generate native configs for Claude, Cursor, Copilot, Windsurf, Gemini, Codex and more.

schemaui turns JSON Schema documents into fully interactive terminal UIs powered by ratatui, crossterm, and jsonschema. The library parses rich schemas (nested sections, $ref, arrays, key/value maps, pattern properties…) into a navigable form tree, renders it as a keyboard-first editor, and validates the result after every edit

painless YAML config files for Python

Rapid YAML - a library to parse and emit YAML, and do it fast.

Easily output ASCII tree from Go program or Markdown unordered list . There's also CLI tool that can output tree from JSON, YAML, or TOML! It's called *xtree*.
