About OneClaw

OneClaw is a local-first, BYOK (Bring Your Own Key) AI agent platform for Android. It runs entirely on the device with no backend server. API keys are encrypted with Android KeyStore. No root access required.

GitHub: https://github.com/GNHua/oneclaw Min SDK: Android 8.0 (API 26) Package: com.oneclaw.shadow

Module Structure

Two Gradle modules:

• :app (com.oneclaw.shadow) -- Main Android application with UI, agent logic, tools, and all features
• :bridge (com.oneclaw.shadow.bridge) -- Standalone Android library for multi-channel messaging (Telegram, Discord, LINE, Slack, Matrix, WebChat)

Architecture (:app module)

Clean Architecture with four layers:

Core Layer (core/)

• model/ -- Domain models: Agent, AiModel, Message, Session, Provider, ScheduledTask, ToolDefinition, SkillDefinition, FileInfo, Attachment, Citation
• repository/ -- Repository interfaces
• util/ -- AppResult<T> sealed class, ErrorCode enum

Data Layer (data/)

• Room database (entities, DAOs, migrations)
• API adapters: OpenAiAdapter, AnthropicAdapter, GeminiAdapter (implement ModelApiAdapter)
• SSE parsing for streaming responses
• EncryptedKeyStorage via EncryptedSharedPreferences
• Google Drive sync (data/sync/)

Feature Layer (feature/)

Each feature has screens, ViewModels, UI state, and use cases: agent, bridge, chat, file, memory, provider, schedule, search, session, settings, skill, tool, usage

Tool Layer (tool/)

• ToolRegistry, ToolExecutionEngine, PermissionChecker
• 39 built-in Kotlin tools in tool/builtin/
• QuickJS JavaScript engine in tool/js/
• Skill management in tool/skill/

DI

Koin with 8 modules: appModule, bridgeModule, databaseModule, featureModule, memoryModule, networkModule, repositoryModule, toolModule

AI Providers

Three providers, selected via ProviderType enum:

API keys are stored encrypted in EncryptedSharedPreferences, never in Room. Providers and models are managed via Settings or the create_provider, add_model tools.

Skills System

Skills are Markdown prompt templates stored as SKILL.md files.

Locations:

• Built-in: app/src/main/assets/skills/<name>/SKILL.md
• User-created: filesDir/skills/<name>/SKILL.md

Built-in skills: create-skill, create-tool, about-oneclaw

Invocation: /skill-name in chat, UI skill selector, or load_skill tool

SKILL.md format:

---
name: skill-name
display_name: Display Name
description: One-line description
version: "1.0"
tools_required:
  - tool_name
parameters:
  - name: param
    type: string
    required: false
    description: Description
---

# Prompt content
Use {{param}} for substitution.

Memory System

Long-term memory: filesDir/memory/MEMORY.md -- injected into every system prompt

• Categories: profile, preferences, interests, workflow, projects, notes
• Managed via save_memory and update_memory tools

Daily logs: filesDir/memory/daily/YYYY-MM-DD.md -- auto-written at session end, app background, session switch, day change, pre-compaction

Hybrid search: BM25 (30%) + vector embeddings (70%) + time decay

• Embedding model: MiniLM-L6-v2 via ONNX Runtime, 384-dimensional vectors

Git versioning (FEAT-050): All text files auto-committed via JGit

• Auto-commit triggers: MEMORY.md update, daily log append, file write/delete
• Browse history in Memory screen via the history icon

Messaging Bridge (:bridge module)

Channels: Telegram, Discord, LINE, Matrix (placeholder), Slack (placeholder), WebChat (placeholder)

Key components:

• MessagingBridgeService -- Foreground service managing all channels
