What problem does it solve? Managing configuration files for multiple AI coding assistants (Claude Code, Cursor, Copilot, Codex CLI, and others) means duplicating rules, permissions, and MCP server settings across incompatible formats. This Skill helps you edit Rulesync JSONC configuration correctly, select the right target-feature combinations, and diagnose why generated files are missing or stale. ## Core Features & Use Cases - Configuration Management: Edit rulesync.jsonc and rulesync.local.jsonc to control which providers and features (rules, permissions, MCP, skills, commands, hooks) are generated, including object-form per-target feature selection. - Generation and Import Workflows: Run rulesync generate, rulesync import, rulesync fetch, and rulesync install with correct input roots, global scope, and dry-run validation. - Diagnosing Stale Output: Trace missing generated files back to feature selection, source discovery, or scope mismatches instead of editing generated files directly. - Use Case: You changed .rulesync/permissions.json but Codex CLI permissions did not update. The Skill guides you to check whether targets.codexcli includes the permissions feature before regenerating. ## Quick Start Ask the assistant to review your rulesync.jsonc configuration and run a dry-run generation to verify the intended target-feature output.
