What It Does
Enable cross-vendor agent-to-agent communication using file-based P2P messaging. Routes messages between models like Claude, Codex, and Gemini by writing and reading transport files (git/CLI friendly) Tool Use Pattern, letting heterogeneous agents interoperate without a centralized broker. Includes a TypeScript CLI and git-backed transport for reproducible, auditable exchanges. This approach aligns with the Agentic RAG Pattern for agent collaboration.
Key Benefits
As agents delegate work across different LLM providers, a common transport and audit trail becomes essential for trust and post-hoc evaluation. Tap provides a lightweight, vendor-agnostic channel that makes agent interactions observable and replayable, giving evaluators and reputation systems the raw interaction logs they need. Until standardized A2A transports are widespread, file-backed, auditable messaging is a practical way to capture agent track records and failure modes. Agent Protocol
Best For
Teams prototyping interoperable multi-vendor agent flows who need auditable, git-friendly message exchange between different LLMs. Guardrails Pattern
Use Cases
- When you need auditable agent interaction logs for reputation and replay
- Connecting heterogeneous LLMs (claude, codex, gemini) in a P2P workflow without a central broker
- Prototyping agent delegation patterns in air-gapped or offline environments using git-backed transports
