Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Epicenter workspace API patterns: `defineWorkspace`, `defineTable`, `defineKv`, table `.docs(...)`, migrations, actions, `connect(...)`, `mount(...)`, materializers, and lower-level `createWorkspace` / `openCollaboration` primitives. Use when editing workspace schemas, table/KV access, row child docs, actions, runtime connections, daemon mounts, or collaboration setup.
How a workspace-backed app under `apps/*` is composed: the isomorphic doc factory (`create<App>`), the environment factories (`open<App>Browser` / `open<App>Extension` / tauri) with the one boot call (`connect(toConnection(auth, nodeId))`, ADR-0088/ADR-0094), the `#platform/*` build-time platform DI for multi-platform (Tauri) apps, the workspace singleton, the sign-in migration wiring, daemon/script placement under per-project `workspaces/<app>/`, and the file layout itself. Use when creating a new app, naming or placing the iso/browser/extension factory, wiring `#platform/*` subpath imports for a Tauri seam, placing the workspace singleton, wiring the first-sign-in migration, registering daemon/script bindings, or gating first paint on local storage hydration (load gate vs WorkspaceGate).
Reap merged git worktrees and branches safely across the warp, codex, opencode, and conductor harnesses. Use when worktrees pile up, after a branch merges, when cleaning up `git worktree list`, removing an orphaned or detached worktree, or deciding whether a worktree is safe to delete. Not for creating branches or authoring commits (use the git skill).
WXT browser extension patterns for entrypoints, background service workers, content scripts, side panels, storage, permissions, host permissions, browser compatibility, and build commands. Use when editing apps/tab-manager, wxt.config.ts, src/entrypoints, extension manifests, or @wxt-dev/storage usage.
Yjs CRDT patterns, shared types (Y.Map, Y.Array, Y.Text), transactions, y-protocols sync and awareness, y-indexeddb persistence, conflict resolution, and document storage. Use when mentioning Yjs, Y.Doc, CRDTs, collaborative editing, real-time sync, awareness, IndexeddbPersistence, or Yjs providers.
Add or modify a feature in the Mistral Vibe Python CLI while following the app architecture ADRs. Use when working in vibe/core, vibe/cli, vibe/acp, vibe/setup, built-in tools, config, sessions, skills, hooks, MCP, connectors, or other Vibe feature code.
Plan analytics instrumentation for a feature. Use when implementing any feature — every feature must ship with telemetry. Decides which events and properties the metrics need (funnels, adoption, status flows), checks compatibility with the existing datalake and event registry, and walks through local, staging, and production verification.
Create or update Architecture Decision Records for the Mistral Vibe Python CLI. Use when a design discussion creates a new architectural constraint, when an undocumented convention causes confusion or review feedback, or when architecture guidance in docs/adr or AGENTS.md must be changed.
Write or refactor Mistral Vibe tests with proper decoupling. Use when adding behavior coverage, testing ports/adapters, replacing brittle mocks, creating fakes, adding characterization tests before refactors, or changing tests under tests/ for vibe/core, vibe/cli, vibe/acp, tools, config, sessions, skills, hooks, MCP, or setup.
Focus on explaining how to use the useXChat Hook, including custom Provider integration, message management, error handling, multi-conversation management, and more
