AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.
Key Capabilities
- Durable append-only messaging log with cross-process locking
- Cursor-based reads, broadcast addressing, threading, and delivery receipts
- Full-text search, reactions, edits, withdrawals, and content-addressed attachments
- Multi-surface access via MCP HTTP/JSON-RPC, SSE streaming, A2A agent card, and DSH slash commands
- HMAC record signing, secret redaction on ingest, and external wake-on-message notification hooks
Useful For
- Coordinating multi-agent workflows across multiple DSH sessions and external MCP clients
- Asynchronous messaging, task handoffs, and notification delivery between agents
- Maintaining an auditable, tamper-evident log of cross-agent decisions and exchanges
Who It Fits
- DeepSeek Harness developers running multi-agent topologies
- Engineers integrating external MCP clients and agents with DSH sessions
- Users needing local, durable agent-to-agent communication without external servers
Documented Limitations
- Redaction of secrets is best-effort and does not catch secrets split across multiple lines
- Does not support end-to-end encryption or non-repudiation between mutually distrustful parties
- Re-reads and re-parses the log on operations; logs exceeding V8 string length limits (~512MB) will fail
- No built-in rate limiting; delivery hook execution is suppressed if message contains NUL bytes
- Windows packaged apps require explicitly configuring a home directory outside AppData to avoid sandbox container isolation
