ya-claw 0.63.0

Workspace-native local-first agent runtime built on top of ya-agent-sdk

YA Claw

Workspace-native single-node agent runtime and web service for the ya-mono workspace.

Scope

YA Claw packages a durable runtime shell around ya-agent-sdk with:

• one persistent workspace resolved through WorkspaceProvider
• reusable agent profiles
• resumable sessions and runs
• in-process active state and async task coordination
• session schedules for timed execution
• SQLite-first durable state with optional PostgreSQL
• local filesystem session continuity and exported state
• a bundled web shell for local and self-hosted use
• bridge adapters that connect IM channels to the YA Claw service

Current Direction

The target single-node shape runs as one web service. The runtime keeps active session state, live delivery, async tasks, schedule dispatch, and bridge coordination inside one runtime process. SQLite is the default durable store. PostgreSQL remains an optional storage backend for deployments that prefer an external relational database.

Layout

Key areas in this package:

• .env.example — runtime environment example
• spec/ — architecture and runtime design documents
• tests/ — runtime tests
• ya_claw/api/ — HTTP API surface
• ya_claw/bridge/ — IM bridge adapters and relay logic
• ya_claw/app.py and ya_claw/cli.py — application entrypoints
• ya_claw/config.py — runtime configuration

Runtime Shape

The runtime shape is:

• one YA Claw web service
• one in-process runtime state manager
• one session scheduler
• one bridge subsystem for external channels
• one shared bearer token for HTTP access
• one SQLite database by default
• optional PostgreSQL
• one runtime data directory for sensitive session continuity
• one persistent workspace directory
• one bundled web shell

Quick Start

From the workspace root, start the default runtime flow:

uv sync --all-packages
cp packages/ya-claw/.env.example packages/ya-claw/.env
make run-claw

Set YA_CLAW_API_TOKEN before starting the service. The development server listens on http://127.0.0.1:9042 by default. YA Claw loads YA_CLAW_* settings from packages/ya-claw/.env and the process environment. YA Claw startup also exports provider variables such as GATEWAY_API_KEY and GATEWAY_BASE_URL from packages/ya-claw/.env into the process environment. Use packages/ya-agent-sdk/.env.example for shared SDK and tool environment variables when you want the same keys outside YA Claw startup. Set YA_CLAW_PROFILE_SEED_FILE plus YA_CLAW_AUTO_SEED_PROFILES=true when you want packaged profiles to seed into the database on startup. Seeded profiles use create/update semantics: every startup refreshes matching database profiles from the YAML file, including subagent configuration, while profiles absent from the YAML file remain in the database. Runs auto-dispatch through the built-in coordinator and resolve model/runtime behavior from AgentProfile rows. The default profile name is default.

Profile, MCP, and coordinator settings:

• YA_CLAW_PROFILE_SEED_FILE=packages/ya-claw/profiles.yaml

• YA_CLAW_BRIDGE_ENABLED_ADAPTERS=lark
• YA_CLAW_BRIDGE_LARK_APP_ID=cli_xxx

Profiles store model, prompt, model context config, builtin tool groups, subagents, approval policy, MCP server definitions, and MCP namespace filters. YA Claw accepts profile MCP servers with streamable_http transport. Every YA Claw agent runtime receives the profile MCP configuration through ToolProxyToolset, and each profile can narrow that surface with enabled_mcps and disabled_mcps.

Session and run requests use the shared workspace configured by YA_CLAW_WORKSPACE_DIR. YA Claw maps that host directory to /workspace for file operations and shell execution. Workspace guidance loads from /workspace/AGENTS.md, and workspace skills are discovered from /workspace/.agents/skills/.

Workspace environments receive LARK_APP_ID and LARK_APP_SECRET from explicit process environment values or from the configured Lark bridge app settings. The official Docker workspace entrypoint writes these values into /home/claw/.lark-cli/config.json for lark-cli bot commands, and clears LARKSUITE_CLI_APP_ID / LARKSUITE_CLI_APP_SECRET in the container runtime environment so lark-cli uses the generated config profile. LARKSUITE_CLI_BRAND, LARKSUITE_CLI_DEFAULT_AS, and LARKSUITE_CLI_STRICT_MODE tune that generated profile. YA_CLAW_WORKSPACE_ENV_VARS forwards additional comma-separated process environment variable names into workspace environments. For Docker workspaces, forwarded values are passed at reusable workspace container creation time.

The default Docker workspace image is ghcr.io/wh1isper/ya-claw-workspace:latest. It is based on Debian stable and includes Python, Node.js, Debian Chromium, the agent-browser CLI, and an agent-browser discovery skill copied into mounted workspaces at container start. Auto-started workspace containers receive YA_CLAW_WORKSPACE_UID, YA_CLAW_WORKSPACE_GID, YA_CLAW_HOST_UID, and YA_CLAW_HOST_GID; the default values come from the YA Claw service process UID/GID and can be overridden with YA_CLAW_WORKSPACE_PROVIDER_DOCKER_UID and YA_CLAW_WORKSPACE_PROVIDER_DOCKER_GID. Docker exec uses YA_CLAW_WORKSPACE_PROVIDER_DOCKER_EXEC_USER=auto by default, which resolves to the configured workspace UID:GID, and sets HOME from YA_CLAW_WORKSPACE_PROVIDER_DOCKER_HOME with default /home/claw. YA_CLAW_WORKSPACE_PROVIDER_DOCKER_EXTRA_MOUNTS adds comma-separated host_path:container_path[:mode] mounts to Docker workspace containers, with rw and ro modes. Docker workspace containers reuse one stable container for the configured workspace, cache the container ID under ~/.ya-claw/data/docker-workspace-containers, check running and Docker health status before each reuse, start stopped containers, and refresh the cache after container recreation. Use agent-browser skills get core inside a workspace session for the version-matched browser automation workflow.

Profiles can be managed through:

• REST API: /api/v1/profiles
• Seed API: POST /api/v1/profiles/seed
• CLI: ya-claw profiles seed

Default local paths:

• SQLite database: ~/.ya-claw/ya_claw.sqlite3
• runtime data root: ~/.ya-claw/data
• workspace directory: ~/.ya-claw/data/workspace

External Database

Set YA_CLAW_DATABASE_URL in packages/ya-claw/.env when you want an external PostgreSQL database. The default SQLite file stays at ~/.ya-claw/ya_claw.sqlite3.

Database Commands

uv run --package ya-claw ya-claw db upgrade
uv run --package ya-claw ya-claw db current
uv run --package ya-claw ya-claw db history
uv run --package ya-claw ya-claw db revision "add session tables"

Bridge Commands

The CLI owns a top-level bridge command group.

uv run --package ya-claw ya-claw bridge ls
uv run --package ya-claw ya-claw bridge run lark
uv run --package ya-claw ya-claw bridge serve lark

Bridge Dispatch

Bridge dispatch controls whether the YA Claw HTTP server starts bridge adapters:

• embedded starts enabled adapters inside the YA Claw server lifespan under BridgeSupervisor.
• manual starts the YA Claw HTTP server without starting BridgeSupervisor.

Bridge adapters submit inbound events through the same session/run controller path used by HTTP requests, so bridge ingress behaves as a self-request inside the service process. The Lark bridge reads YA_CLAW_BRIDGE_LARK_EVENT_TYPES as a comma-separated event allowlist. The default allowlist covers bot-added-to-chat, user-added-to-chat, message receive, and Drive comment notification events. Message receive events map each tenant_key + chat_id pair to one YA Claw session. Other Lark events use chat_id when present and fall back to a stable event or Drive conversation key. Every accepted inbound event creates a queued bridge-triggered run, and the agent replies or acts from the workspace with lark-cli.

Web Shell

Run the web shell from the repository root:

make web-dev

Docker

Build the YA Claw service image from the repository root:

docker build -f Dockerfile.ya-claw -t ya-claw:dev .

Build the official workspace image locally:

docker build -f Dockerfile.ya-claw-workspace -t ya-claw-workspace:dev .

Build the workspace image with a default UID/GID baked in:

docker build \
  --build-arg WORKSPACE_UID=1000 \
  --build-arg WORKSPACE_GID=1000 \
  -f Dockerfile.ya-claw-workspace \
  -t ya-claw-workspace:dev .

Run the YA Claw service image under a specific UID/GID:

docker run \
  -e YA_CLAW_RUN_UID=1000 \
  -e YA_CLAW_RUN_GID=1000 \
  -e YA_CLAW_API_TOKEN=replace-with-a-long-random-token \
  ya-claw:dev
