+# 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
+```
+
+## MCP Registration
+
+### How MCPs Are Configured in Claude Code
+
+**MCPs must be registered via `claude mcp add` — not by hand-editing `~/.claude/settings.json`.**
+
+`settings.json` controls hooks, model, plugins, and allowed commands. The `mcpServers` key in
+`settings.json` is silently ignored by Claude Code's MCP loader. The correct file is `~/.claude.json`,
+which is managed by the `claude mcp` CLI.
+
+```bash
+# Register a stdio MCP (user scope = all projects, persists across sessions)
+claude mcp add --scope user <name> -- npx -y <package>
+
+# Register an HTTP MCP (e.g. OpenBrain)
+claude mcp add --scope user --transport http <name> <url> \
+  --header "Authorization: Bearer <token>"
+
+# List registered MCPs
+claude mcp list
+```
+
+**Scope options:**
+- `--scope user` — writes to `~/.claude.json`, available in all projects (recommended for shared tools)
+- `--scope project` — writes to `.claude/settings.json` in the project root, committed to the repo
+- `--scope local` — default, machine-local only, not committed
+
+**Transport for HTTP MCPs must be `http`** — not `sse`. `type: "sse"` is a deprecated protocol
+that silently fails to connect against FastMCP streamable HTTP servers.
+
+### sequential-thinking MCP (Hard Requirement)
+
+sequential-thinking MCP is required for Mosaic Stack. The installer registers it automatically.
+To verify or re-register manually:
+
+```bash
+~/.config/mosaic/bin/mosaic-ensure-sequential-thinking
+~/.config/mosaic/bin/mosaic-ensure-sequential-thinking --check
+```
+
+### OpenBrain Semantic Memory (Recommended)
+
+OpenBrain is the shared cross-agent memory layer. Register once per machine:
+
+```bash
+claude mcp add --scope user --transport http openbrain https://your-openbrain-host/mcp \
+  --header "Authorization: Bearer YOUR_TOKEN"
+```
+
+See [mosaic/openbrain](https://git.mosaicstack.dev/mosaic/openbrain) for setup and API docs.
+
+## 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
+```
