aiconfigsync 1.0.0

Generate AI coding assistant config files from a single source. 12 tools, 1 command.

config-sync

Write once. AI everywhere.

Generate config files for 12 AI coding assistants from a single source of truth.

The Problem

Every AI coding tool uses a different config file:

Tool	Config File
Claude Code	CLAUDE.md + .claude/rules/
Codex CLI / Amp / OpenCode / Warp	AGENTS.md
Gemini CLI	GEMINI.md
Cursor	.cursor/rules/*.mdc
GitHub Copilot	.github/copilot-instructions.md
Windsurf	.windsurf/rules/
Cline / Roo Code	.clinerules/
Aider	CONVENTIONS.md
Kiro	.kiro/steering/
Amazon Q	.amazonq/rules/
Goose	.goosehints
Trae AI	.trae/rules/
Zed	.rules

Change a rule? Update 13 files. Or let config-sync do it.

Install

pip install git+https://github.com/nadalpiantini/config-sync.git

Or with pipx (recommended for CLI tools):

pipx install git+https://github.com/nadalpiantini/config-sync.git

Or clone and install locally:

git clone https://github.com/nadalpiantini/config-sync.git
cd config-sync
pip install -e .

Usage

Generate all configs

config-sync /path/to/your/repo

Generate specific tools

config-sync /path/to/your/repo --tools codex,gemini,cursor

Preview without writing

config-sync /path/to/your/repo --dry-run

Migrate from CLAUDE.md

Already have a CLAUDE.md? Split it into .claude/rules/ (the canonical source):

config-sync /path/to/your/repo --init

List supported tools

config-sync --list-tools

How It Works

┌─────────────────────┐
│  .claude/rules/     │  ← your single source of truth
└─────────┬───────────┘
          │ config-sync
    ┌─────┼─────────────────────────┐
    ▼     ▼     ▼     ▼     ▼       ▼
 AGENTS  GEMINI CURSOR COPILOT WINDSURF CLINE
   .md    .md   /rules   .md    /rules   /rules
                                         ▼
                              AIDER KIRO AMAZON-Q GOOSE TRAE ZED
                               .md /steer /rules  hints /rules .rules

1. Source: .claude/rules/*.md — the most expressive format (frontmatter, glob patterns, conditional loading)
2. Transform: Concatenate rules, strip tool-specific frontmatter, adapt format per tool
3. Output: Native configs for each tool with <!-- Generated by config-sync --> headers

Smart Detection

Auto-detects which tools are already configured in your repo and reports them:

$ config-sync ./my-project
Source: 2,847 chars
Detected: cursor, copilot, codex
Generating: codex, gemini, cursor, copilot, windsurf, cline, aider, kiro, amazonq, goose, trae, zed

  + AGENTS.md (2,937 chars)
  + GEMINI.md (2,937 chars)
  + .cursor/rules/config-sync.mdc (2,933 chars)
  ...

Format Adaptations

Each tool gets properly formatted output:

• Cursor: MDC frontmatter with globs: ** and alwaysApply: true
• Aider: Condensed to bullet points
• Goose: Plain text, one rule per line (no markdown)
• All others: Flat markdown with generated header

Supported Tools

Tool	Output File	Format
Codex / Amp / OpenCode / Warp	AGENTS.md	Markdown
Gemini CLI	GEMINI.md	Markdown
Cursor	.cursor/rules/config-sync.mdc	MDC
GitHub Copilot	.github/copilot-instructions.md	Markdown
Windsurf	.windsurf/rules/config-sync.md	Markdown
Cline / Roo Code	.clinerules/config-sync.md	Markdown
Aider	CONVENTIONS.md	Condensed bullets
Kiro (AWS)	.kiro/steering/config-sync.md	Markdown
Amazon Q	.amazonq/rules/config-sync.md	Markdown
Goose (Block)	.goosehints	Plain text
Trae AI	.trae/rules/config-sync.md	Markdown
Zed	.rules	Markdown

Philosophy

Write once in the richest format. Compile to every target.

.claude/rules/ is your source code. The generated configs are compiled output. Edit the source, re-run config-sync, commit all files together.

Requirements

• Python 3.10+
• Zero external dependencies
