# Mosaic Agent Framework

Universal agent standards layer for Claude Code, Codex, and OpenCode.

One config, every runtime, same standards.

> **This repository is a generic framework baseline.** No personal data, credentials, user-specific preferences, or machine-specific paths should be committed. All personalization happens at install time via `mosaic init` or by editing files in `~/.config/mosaic/` after installation.

## Quick Install

### Mac / Linux

```bash
curl -sL https://git.mosaicstack.dev/mosaic/bootstrap/raw/branch/main/remote-install.sh | sh
```

### Windows (PowerShell)

```powershell
irm https://git.mosaicstack.dev/mosaic/bootstrap/raw/branch/main/remote-install.ps1 | iex
```

### From Source (any platform)

```bash
git clone https://git.mosaicstack.dev/mosaic/bootstrap.git ~/src/mosaic-bootstrap
cd ~/src/mosaic-bootstrap && bash install.sh
```

If Node.js 18+ is available, the remote installer automatically uses the TypeScript wizard instead of the bash installer for a richer setup experience.

The installer will:
- Install the framework to `~/.config/mosaic/`
- Add `~/.config/mosaic/bin` to your PATH
- Sync runtime adapters and skills
- Install and configure sequential-thinking MCP (hard requirement)
- Run a health audit
- Detect existing installs and prompt to keep or overwrite local files
- Prompt you to run `mosaic init` to set up your agent identity

## First Run

After install, open a new terminal (or `source ~/.bashrc`) and run:

```bash
mosaic init
```

If Node.js 18+ is installed, this launches an interactive wizard with two modes:

- **Quick Start** (~2 min): agent name + communication style, sensible defaults for everything else
- **Advanced**: full customization of identity, user profile, tools, runtimes, and skills

The wizard configures three files loaded into every agent session:
- `SOUL.md` — agent identity contract (name, style, guardrails)
- `USER.md` — your user profile (name, timezone, accessibility, preferences)
- `TOOLS.md` — machine-level tool reference (git providers, credentials, CLI patterns)

It also detects installed runtimes (Claude, Codex, OpenCode), configures sequential-thinking MCP, and offers curated skill selection from 8 categories.

### Non-Interactive Mode

For CI or scripted installs:

```bash
mosaic init --non-interactive --name Jarvis --style direct --user-name Jason --timezone America/Chicago
```

All flags: `--name`, `--role`, `--style`, `--user-name`, `--pronouns`, `--timezone`, `--mosaic-home`, `--source-dir`.

### Legacy Fallback

If Node.js is unavailable, `mosaic init` falls back to the bash-based `mosaic-init` script.

## Launching Agent Sessions

```bash
mosaic claude              # Launch Claude Code with full Mosaic injection
mosaic codex               # Launch Codex with full Mosaic injection
mosaic opencode            # Launch OpenCode with full Mosaic injection
```

The launcher:
1. Verifies `~/.config/mosaic` exists
2. Verifies `SOUL.md` exists (auto-runs `mosaic init` if missing)
3. Injects `AGENTS.md` into the runtime
4. Forwards all arguments to the runtime CLI

You can still launch runtimes directly (`claude`, `codex`, etc.) — thin runtime adapters will tell the agent to read `~/.config/mosaic/AGENTS.md`.

### How AGENTS.md Gets Loaded

| Launch method | Injection mechanism |
|--------------|-------------------|
| `mosaic claude` | `--append-system-prompt` with composed runtime contract (`AGENTS.md` + runtime reference) |
| `mosaic codex` | Writes composed runtime contract to `~/.codex/instructions.md` before launch |
| `mosaic opencode` | Writes composed runtime contract to `~/.config/opencode/AGENTS.md` before launch |
| `claude` (direct) | `~/.claude/CLAUDE.md` thin pointer → load AGENTS + runtime reference |
| `codex` (direct) | `~/.codex/instructions.md` thin pointer → load AGENTS + runtime reference |
| `opencode` (direct) | `~/.config/opencode/AGENTS.md` thin pointer → load AGENTS + runtime reference |

Mosaic `AGENTS.md` enforces loading `guides/E2E-DELIVERY.md` before execution and
requires `guides/PRD.md` before coding and `guides/DOCUMENTATION.md` for code/API/auth/infra documentation gates.

## Management Commands

```bash
mosaic help                # Show all commands
mosaic init                # Interactive wizard (or legacy init)
mosaic doctor              # Health audit — detect drift and missing files
mosaic sync                # Sync skills from canonical source
mosaic bootstrap <path>    # Bootstrap a repo with Mosaic standards
mosaic upgrade check       # Check release upgrade status (no changes)
mosaic upgrade             # Upgrade installed Mosaic release (keeps SOUL.md by default)
mosaic upgrade --dry-run   # Preview release upgrade without changes
mosaic upgrade --ref main  # Upgrade from a specific branch/tag/commit ref
mosaic upgrade --overwrite # Upgrade release and overwrite local files
mosaic upgrade project ... # Project file cleanup mode (see below)
```

## Upgrading Mosaic Release

Upgrade the installed framework in place:

```bash
# Default (safe): keep local SOUL.md, USER.md, TOOLS.md + memory
mosaic upgrade

# Check current/target release info without changing files
mosaic upgrade check

# Non-interactive
mosaic upgrade --yes

# Pull a specific ref
mosaic upgrade --ref main

# Force full overwrite (fresh install semantics)
mosaic upgrade --overwrite --yes
```

`mosaic upgrade` re-runs the remote installer and passes install mode controls (`keep`/`overwrite`).
This is the manual upgrade path today and is suitable for future app-driven update checks.

## Upgrading Projects

After centralizing AGENTS.md and SOUL.md, existing projects may have stale files:

```bash
# Preview what would change across all projects
mosaic upgrade project --all --dry-run

# Apply to all projects
mosaic upgrade project --all

# Apply to a specific project
mosaic upgrade project ~/src/my-project
```

Backward compatibility is preserved for historical usage:

```bash
mosaic upgrade --all          # still routes to project-upgrade
mosaic upgrade ~/src/my-repo  # still routes to project-upgrade
```

What it does per project:

| File | Action |
|------|--------|
| `SOUL.md` | Removed — now global at `~/.config/mosaic/SOUL.md` |
| `CLAUDE.md` | Replaced with thin pointer to global AGENTS.md |
| `AGENTS.md` | Stale load-order sections stripped; project content preserved |

Backups (`.mosaic-bak`) are created before any modification.

## Universal Skills

The installer syncs skills from `mosaic/agent-skills` into `~/.config/mosaic/skills/`, then links each skill into runtime directories (`~/.claude/skills`, `~/.codex/skills`, `~/.config/opencode/skills`).

```bash
mosaic sync                                    # Full sync (clone + link)
~/.config/mosaic/bin/mosaic-sync-skills --link-only   # Re-link only
```

## Runtime Compatibility

The installer pushes thin runtime adapters as regular files (not symlinks):

- `~/.claude/CLAUDE.md` — pointer to `~/.config/mosaic/AGENTS.md`
- `~/.claude/settings.json`, `hooks-config.json`, `context7-integration.md`
- `~/.config/opencode/AGENTS.md` — pointer to `~/.config/mosaic/AGENTS.md`
- `~/.codex/instructions.md` — pointer to `~/.config/mosaic/AGENTS.md`
- `~/.claude/settings.json`, `~/.codex/config.toml`, and `~/.config/opencode/config.json` include sequential-thinking MCP config

Re-sync manually:

```bash
~/.config/mosaic/bin/mosaic-link-runtime-assets
```

## sequential-thinking MCP Requirement

sequential-thinking MCP is a hard requirement for Mosaic Stack.

Use:

```bash
~/.config/mosaic/bin/mosaic-ensure-sequential-thinking
~/.config/mosaic/bin/mosaic-ensure-sequential-thinking --check
```

## Bootstrap Any Repo

Attach any repository to the Mosaic standards layer:

```bash
mosaic bootstrap /path/to/repo
```

This creates `.mosaic/`, `scripts/agent/`, and an `AGENTS.md` if missing.

## Quality Rails

Apply and verify quality templates:

```bash
~/.config/mosaic/bin/mosaic-quality-apply --template typescript-node --target /path/to/repo
~/.config/mosaic/bin/mosaic-quality-verify --target /path/to/repo
```

Templates: `typescript-node`, `typescript-nextjs`, `monorepo`

## Health Audit

```bash
mosaic doctor                                          # Standard audit
~/.config/mosaic/bin/mosaic-doctor --fail-on-warn      # Strict mode
```

## Wizard Development

The installation wizard is a TypeScript project in the root of this repo.

```bash
pnpm install              # Install dependencies
pnpm dev                  # Run wizard from source (tsx)
pnpm build                # Bundle to dist/mosaic-wizard.mjs
pnpm test                 # Run tests (30 tests, vitest)
pnpm typecheck            # TypeScript type checking
```

The wizard uses `@clack/prompts` for the interactive TUI and supports `--non-interactive` mode via `HeadlessPrompter` for CI and scripted installs. The bundled output (`dist/mosaic-wizard.mjs`) is committed to the repo so installs work without `node_modules`.

## Re-installing / Updating

Pull the latest and re-run the installer:

```bash
cd ~/src/mosaic-bootstrap && git pull && bash install.sh
```

If an existing install is detected, the installer prompts for:
- `keep` (recommended): preserve local `SOUL.md`, `USER.md`, `TOOLS.md`, and `memory/`
- `overwrite`: replace everything in `~/.config/mosaic`

Or use the one-liner again — it always pulls the latest:

```bash
curl -sL https://git.mosaicstack.dev/mosaic/bootstrap/raw/branch/main/remote-install.sh | sh
```
