Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
agnix
Lint agent configurations before they silently fail. 414 validation rules across Claude Code, Codex CLI, OpenCode, Cursor, GitHub Copilot, Gemini CLI, Cline, Windsurf, Roo Code, Amp, and Kiro - validates CLAUDE.md, AGENTS.md, SKILL.md, hooks.json, MCP server configs, and plugin manifests. Auto-fix included for safe issues; SARIF output for GitHub Code Scanning. Distributed as CLI (npm + Cargo), official GitHub Action (`agent-sh/agnix`), and IDE extensions for VS Code, JetBrains, Neovim, and Zed. Rules sourced from official specs, academic research on agent prompt design, and real-world failure patterns from production deployments. Mentioned in awesome-claude-code.
claude-code-survival-kit
10 slash commands and 3 agent definitions distilled from 6 months of daily Claude Code use. Not a framework -- just the patterns that survived: multi-agent build pipelines, parallel task dispatch, security audits, session handoffs, and more.
