OpenPets Dev 6ab3bb64d8 feat(rebrand): rename OpenPets to FamiliarOS and pets to familiars
- Rename all user-facing and technical identifiers from OpenPets/Pet to FamiliarOS/Familiar.
- Rename packages from @open-pets/* to @familiaros/*; rename install-pet/pet-format packages.
- Rename plugin IDs and directories from openpets.* to familiaros.*.
- Rename IPC namespace from openpets:* to familiaros:* and state filenames from openpets-* to familiaros-* with legacy migration.
- Rename source files (pet-window, built-in-pet, default-pet-controller, etc.) to familiar equivalents.
- Update locales (en, es-419, ja, ko, pt-BR, zh-Hans, zh-Hant) and tray/pet context menu strings.
- Add Familiar naming feature: preference, settings input, tray menu display.
- Update assets and packaging config; all desktop tests pass.

Repository Atlas: FamiliarOS 2.0 Workspace

Project Responsibility

FamiliarOS is a pnpm/TypeScript monorepo for an Electron desktop companion app plus npm packages that let coding agents control animated desktop familiars. The workspace provides a local IPC protocol, MCP server, CLI tooling, and editor-specific integrations for Claude Code, OpenCode, Cursor, and Pi.

System Entry Points

  • package.json: workspace scripts for building, checking, testing, desktop packaging, and npm release orchestration.
  • pnpm-workspace.yaml: workspace membership for apps/* and packages/*.
  • apps/desktop/src/main.ts: Electron main-process bootstrap for the desktop familiar app.
  • packages/cli/src/index.ts: command-line setup and familiar management entry point.
  • packages/mcp/src/index.ts: MCP server entry point used by agents.
  • packages/client/src/index.ts: public IPC client API consumed by integrations and tools.
  • packages/cursor/src/index.ts: Cursor MCP/rules setup API.
  • packages/pi/src/extension.ts: Pi coding-agent extension runtime entry point.
  • plugins/official/: first-party plugin product source consumed by desktop dev mode and web catalog sync.

Architecture Flow

  1. The desktop app starts apps/desktop/src/main.ts, initializes app state, creates tray/task windows, and starts a local IPC server.
  2. Agent integrations (packages/claude, packages/opencode, packages/cursor, packages/pi, and packages/mcp) configure agents or emit familiar commands through @familiaros/client.
  3. The client discovers Unix sockets, Windows named pipes, or TCP endpoints for WSL cross-platform access.
  4. The desktop IPC server routes commands through lease-managed controllers so default and agent familiars can coexist safely.
  5. The plugin service loads approved catalog or local familiaros.plugin.json manifests, persists plugin state/config, schedules declarative timers, and bridges allowed actions into the default familiar API.
  6. Familiar windows render reaction-driven animations, speech bubbles, and status badges using desktop state plus reaction mapping metadata.
  7. Familiar assets are resolved from built-in assets, locally developed Codex familiars, or remotely downloaded catalog ZIPs.
  8. Workspace packages share TypeScript/ESM build conventions and are wired together through pnpm workspace:* dependencies.

Working Notes

  • For repository-level orientation, start here, then open the specific folder codemap before editing.
  • Contract validation files named check-*.ts are intentionally excluded from detailed codemap coverage.
  • Build artifacts, dependencies, tests, documentation, and binary assets are excluded from codemap state.
