code-agnostic 0.3.2

Centralized hub for LLM coding config: MCP, skills, rules, and agents.

code-agnostic

One config, every AI editor. Keep MCP servers, rules, skills, and agents in a single hub and sync them into editor-specific layouts.

Why

AI coding tools each want config in a different place and format. When you use more than one, you end up copy-pasting MCP servers, duplicating rules, and manually keeping things in sync. code-agnostic removes that overhead: define once, sync everywhere.

How it works

~/.config/code-agnostic/          Your single source of truth
├── config/
│   └── mcp.base.json             MCP servers (editor-agnostic)
├── rules/
│   └── python-style.md           Rules with YAML frontmatter
├── skills/
│   └── code-reviewer/SKILL.md    Skills with YAML frontmatter
└── agents/
    └── architect.md              Agents with YAML frontmatter

        ↓ plan / apply ↓

~/.config/opencode/               Compiled & synced for OpenCode
~/.cursor/                        Compiled & synced for Cursor
~/.codex/                         Compiled & synced for Codex

Each resource is cross-compiled to the target editor's native format. Rules become .mdc files for Cursor, AGENTS.md sections for OpenCode/Codex, etc.

Today the implementation is still mixed: some assets are compiled and some are symlinked. The active migration plan is to move to generated outputs everywhere with a strict compiler contract instead of implicit per-app behavior.

Install

uv tool install code-agnostic

Or run without installing:

uvx code-agnostic

Or run the published Docker image to isolate filesystem access to mounted paths only:

docker run --rm -it \
  -v "$(pwd):/workspace" \
  -w /workspace \
  ghcr.io/dhvcc/code-agnostic:latest plan

By default, config stays inside the container at /root/.config unless you mount a host path.

Quick start

# Import existing config from an editor you already use
code-agnostic import plan -a codex
code-agnostic import apply -a codex

# Enable target editors
code-agnostic apps enable -a cursor
code-agnostic apps enable -a opencode

# Preview and apply
code-agnostic plan
code-agnostic apply

Cursor workspace propagation is intentionally disabled to avoid duplicate MCP initialization in multi-root workspaces: https://forum.cursor.com/t/mcp-multi-root-workspace-causes-duplicate-mcp-server-initialization-4x-createclient-actions/144003

OpenCode workspace configs include the shared workspace AGENTS.md natively via instructions, so repos under the workspace get both repo-local and shared workspace instructions.

Cursor documents AGENTS.md as a root-level project file. Codex documents AGENTS.md discovery, but not a native config include for an extra workspace file. In practice that means subdirectories and repos opened below the workspace root will not reliably get the shared workspace AGENTS.md today for Cursor or Codex.

Features

Sync engine

Plan-then-apply workflow. Preview every change before it touches disk.

code-agnostic plan -a cursor        # dry-run for one editor
code-agnostic plan                   # dry-run for all
code-agnostic apply                  # apply changes
code-agnostic status                 # check drift

MCP management

Add, remove, and list MCP servers without editing JSON by hand.

code-agnostic mcp add github --command npx --args @modelcontextprotocol/server-github --env GITHUB_TOKEN
code-agnostic mcp list
code-agnostic mcp remove github

Env vars without a value (--env GITHUB_TOKEN) are stored as ${GITHUB_TOKEN} references.

Rules with metadata

Rules live in rules/ as markdown files with optional YAML frontmatter:

---
description: "Python coding standards"
globs: ["*.py"]
always_apply: false
---

Always use type hints. Prefer dataclasses over dicts.

Cross-compiled per editor: Cursor gets .mdc files with native frontmatter, OpenCode/Codex get AGENTS.md sections.

code-agnostic rules remove --name python-style

Skills and agents

Canonical YAML frontmatter format, cross-compiled per editor.

code-agnostic agents list

Workspaces

Register workspace directories. Workspace rules are compiled into a canonical AGENTS.md and symlinked to the workspace root. Repos keep their own repo-specific AGENTS.md. OpenCode workspace configs also reference the shared workspace file through instructions, so a repo can load both its own AGENTS.md and the workspace-level one. Repo-local app config, skills, and agents are propagated for OpenCode and Codex.

.cursor workspace propagation is intentionally disabled to avoid duplicate MCP initialization when opening multi-root workspaces in Cursor (related issue: https://forum.cursor.com/t/mcp-multi-root-workspace-causes-duplicate-mcp-server-initialization-4x-createclient-actions/144003).

code-agnostic workspaces add --name myproject --path ~/code/myproject
code-agnostic workspaces list

Git exclude

Prevent synced paths from showing up in git status. Managed per-workspace with customizable patterns.

code-agnostic workspaces git-exclude                            # all workspaces
code-agnostic workspaces git-exclude -w myproject               # one workspace
code-agnostic workspaces exclude-add --pattern "*.generated" -w myproject
code-agnostic workspaces exclude-list -w myproject

Import

Migrate existing config from any supported editor into the hub.

code-agnostic import plan -a codex
code-agnostic import apply -a codex
code-agnostic import apply -a cursor --include mcp --on-conflict overwrite
code-agnostic import plan -a codex -i    # interactive TUI picker

CLI conventions

All commands use named flags (-a, -w, -v). Singular aliases work too: app = apps, workspace = workspaces.

• ROADMAP.md
• docs/compiler/overview.md
• docs/compiler/skills.md
• docs/compiler/agents.md
• docs/compiler/rules.md
• docs/compiler/mcp.md
• docs/compiler/lossiness.md

Roadmap

• MCP server sync across editors
• Skills and agents sync (symlink-based)
• Workspace propagation into git repos
• Import from existing editor configs
• Consistent CLI with named flags and aliases
• MCP add/remove/list commands
• Rules system with YAML frontmatter and per-editor compilation
• Cross-compilation for skills and agents
