Rulesync

Rulesync

Documentation | npm

A Node.js CLI tool that automatically generates configuration files for various AI development tools from unified AI rule files. Features selective generation, comprehensive import/export capabilities, and supports major AI development tools with rules, commands, MCP, ignore files, subagents and skills.

Installation

npm install -g rulesync

Or install from our Homebrew tap (macOS and Linux):

brew tap dyoshikawa/rulesync https://github.com/dyoshikawa/rulesync
brew install rulesync

The tap lives inside this repository, so it does not have a homebrew- prefix. The two-argument brew tap <name> <url> form is therefore required — the shorthand brew install dyoshikawa/rulesync/rulesync without tapping first does not work.

Single Binary

curl -fsSL https://github.com/dyoshikawa/rulesync/releases/latest/download/install.sh | bash

See Installation docs for manual install and platform-specific instructions.

Getting Started

# Create necessary directories, sample rule files, and configuration file
rulesync init

# Install official skills (recommended)
rulesync fetch dyoshikawa/rulesync

# Generate unified configurations with all features
rulesync generate --targets "*" --features "*"

If you already have AI tool configurations:

# Import existing files (to .rulesync/**/*)
rulesync import --targets claudecode    # From CLAUDE.md
rulesync import --targets cursor        # From .cursorrules
rulesync import --targets copilot       # From .github/copilot-instructions.md

Want to convert configuration from one AI tool to another directly, without adopting the .rulesync/ source-of-truth workflow?

# Convert Cursor rules to Copilot and Claude Code in one shot (no .rulesync/ files written)
rulesync convert --from cursor --to copilot,claudecode

See Quick Start guide for more details.

Supported Tools and Features

The tables below show whether each tool supports a given feature (✅ = supported, blank = not supported). A ✅ means the feature is supported in at least one mode (project, global, or simulated) — for example, Codex CLI commands is global-only. For each tool's --targets value and full mode breakdown (project / global / simulated / MCP tool config), see the Supported Tools reference.

• ⚠️: Deprecated — still supported, but see the note below

Target and deprecation notes

• Ignore feature — The ignore feature is deprecated in favor of the more expressive permissions feature. Existing ignore configurations remain supported throughout Rulesync 14.x; removal, if any, will be decided separately and will not occur before a future major release. New rulesync init projects scaffold permissions without enabling or creating ignore files. See the migration guide.
• Google Antigravity (antigravity-ide / antigravity-cli) — Antigravity 2.0 splits into two products with separate global config trees: the desktop antigravity-ide and the antigravity-cli (agy). For project-scope rules, both antigravity-ide and antigravity-cli emit the root rule as a plain cross-tool AGENTS.md at the project root (the Gemini-lineage discovery order is AGENTS.md, CONTEXT.md, GEMINI.md; the IDE has read AGENTS.md since v1.20.3) and non-root rules under .agents/rules/. In --global mode, both targets write the root rule to ~/.gemini/GEMINI.md and each non-root rule to its own file in the shared ~/.gemini/config/rules/ (with trigger frontmatter, identical for the two targets), so each rule gets Antigravity's 24,000-byte per-file limit to itself; generate --delete never removes files from that shared directory.
• Plugin packaging (claudecode-plugin / antigravity-plugin / augmentcode-plugin / zcode-plugin / vibe-plugin / devin-plugin / kimi-code-plugin) — These project-only targets generate and import Rulesync-managed components inside an existing plugin directory selected with --output-roots (generate) or --output-root (import). They are excluded from --targets "*" to avoid writing package-level skills/, rules/, or commands/ directories into ordinary projects. Rulesync preserves plugin manifests, marketplace metadata, scripts, and other non-component assets; the only manifest it writes is a missing Antigravity plugin.json, which Antigravity needs to load the plugin at all. See the Plugin Packaging guide.
• Continue (continue) — Continue is end of life: it joined Cursor on 2026-06-18, the continuedev/continue repository is read-only with a final v2.0.0 release (2026-06-19), and its last commit is from 2026-07-21. The continue target stays supported as a frozen-compatibility target verified against that final source tree, so existing output keeps working — it just will not track anything new. See Supported tools > Deprecation notes.
• Kiro (kiro) — Kiro's IDE and CLI use diverging config formats (IDE: Markdown subagents .kiro/agents/*.md; CLI: JSON agent-config subagents .kiro/agents/*.json), so kiro is split into kiro-cli and kiro-ide. The legacy kiro target remains as a deprecated alias with its current behavior unchanged. The two targets share every surface except subagents (Markdown vs JSON); both emit hooks as a single .kiro/hooks/rulesync.json ({ "version": "v1", "hooks": [ ... ] }) in project (.kiro/hooks/) and global (~/.kiro/hooks/) scope, the format Kiro CLI 3.0 migrated to. Only the deprecated kiro alias still writes hooks into .kiro/agents/default.json, which the CLI no longer reads. Global skills (~/.kiro/skills/), global ignore (~/.kiro/settings/kiroignore, which only the IDE reads, so kiro-cli skips it), and global Kiro IDE subagents (~/.kiro/agents/) are supported too, as are global Kiro CLI commands (~/.kiro/prompts/) and subagents (~/.kiro/agents/), and global permissions for kiro-cli/kiro-ide as capability rules in ~/.kiro/settings/permissions.yaml (project permissions stay in .kiro/agents/default.json). Kiro MCP generation preserves per-server disabledTools, and the deprecated kiro alias's hook caching maps cacheTtl to cache_ttl_seconds.
• Tabnine CLI (tabnine) — The file-based Tabnine CLI is in maintenance mode: as of Tabnine 6.6 (2026-09-15) it is "Tabnine CLI (Legacy)" (tabnine-legacy), receiving only critical updates through 2026-12-31. The new tabnine command is Tabnine's distribution of OpenCode and reads standard OpenCode files, so target it with --targets opencode. The tabnine target stays supported for the legacy CLI. See Supported tools > Deprecation notes.
• Roo Code (roo) — Roo Code is end of life: its final release was v3.54.0 (2026-05-15) and its repository is archived. New projects should target zoocode (Zoo Code), the community continuation named by the Roo shutdown notice. The roo target stays supported because Zoo Code still reads the same .roo/ project tree and ~/.roo global tree, so existing output keeps working — it just no longer tracks anything Zoo Code added after the fork. Enable one of the two targets per project, not both. See Supported tools > Deprecation notes.
• Rovo Dev (rovodev) — Atlassian has announced that Rovo Dev as a standalone product will reach end of life (date TBA, with at least 60 days' notice) and that Rovo Dev CLI is evolving into the unified Atlassian Rovo CLI. Until migration instructions are shared, the rovodev target stays supported and keeps emitting the current Rovo Dev CLI files. See Supported tools > Deprecation notes.

Some features accept per-feature options. See Configuration > Per-feature options for details.
