dsh-agent-messaging
Cross-session agent-to-agent messaging, claims, verification, and decision ledger for DeepSeek Harness.
Install
$ npx -p @deepseek-ai/dsh dsh plugin --profile web add dsh-agent-messagingPlugin Overview & Capabilities
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
- Cross-session direct messaging with steer, followup, and context delivery modes
- Resource claim management (peer_claim) to prevent parallel edit collisions and step repetition
- Independent cross-agent claim verification (peer_verify / peer_verify_reply)
- Status reporting and mutual-wait deadlock detection (peer_status)
- Append-only decision ledger (peer_decide / peer_decisions) with supersession tracking
- Agent capability cards and aliasing (peer_card)
- Loop control, duplicate suppression, and rate limiting
- Cost-versus-catch metrics accounting and reporting CLI
- Outbound integration with external Agent2Agent (A2A) endpoints
- Web UI transcript card integration for peer messages
Useful For
- Coordinating multi-agent coding sessions across different directories or worktrees in the same repository
- Preventing concurrent file edits and duplicated labor across parallel DSH sessions
- Verifying assumptions or contract breaking changes by delegating checks to domain-owning peer agents
- Maintaining an append-only decision record so newly started sessions do not reopen settled technical debates
Who It Fits
- Developers running multi-agent workflows in DeepSeek Harness
- Engineers orchestrating parallel modular refactors across multiple worktrees
- Teams using multi-session autonomous coding agents requiring anti-collision and deadlock prevention
Documented Limitations
- Restricted to local single-machine communication via Unix domain sockets (shared filesystem required)
- Transfers plain text messages only; does not support structured payload objects or file attachments
- External Agent2Agent (A2A) connections are outbound-only and strictly treated as unprivileged inform authority
- Spooled offline messages are best-effort and subject to configured expiration and queue depth limits
DSH Compatibility
Version-specific runtime evidence collected by DSH Plugin. A missing result means we have not tested that combination yet.
Security Signals
Objective signals discovered from package metadata and source inspection. These are not a guarantee that a plugin is safe.
package.json declares 0 runtime, 25 development, 12 peer, and 0 optional dependencies.
package.json declares DSH bundle metadata.
GitHub reports the repository license as MIT.
A root package.json was captured and can be inspected by the registry.
package.json declares a prepare lifecycle script that may run during relevant package installation workflows.
Public GitHub source metadata is available for this registry snapshot.
