# `Raxol.AgentClientProtocol`
[🔗](https://github.com/DROOdotFOO/raxol-agent/blob/raxol_agent_client_protocol-v0.1.0/packages/raxol_agent_client_protocol/lib/raxol/agent_client_protocol.ex#L1)

Elixir/OTP implementation of **ACP (Agent Client Protocol)** — the JSON-RPC
2.0 protocol spoken between code editors ("clients") and AI coding agents
("agents"). See <https://agentclientprotocol.com>.

This is the package root. The library is organized in orthogonal layers:

  * `Raxol.AgentClientProtocol.Schema.*` — the ACP data model (content
    blocks, session types, fs/terminal types, capabilities), ported from the
    MIT `f1729/agent_client_protocol` schema layer (see `NOTICE.md`).
  * `Raxol.AgentClientProtocol.Rpc.*` — JSON-RPC 2.0 envelope: id
    correlation (`null | integer | string`, type-preserving), error codes,
    total decoding.
  * `Raxol.AgentClientProtocol.Transport.*` — pluggable byte/message
    carriers: `stdio` (newline-delimited JSON) and an in-process paired
    transport for tests and BEAM-local wiring.
  * `Raxol.AgentClientProtocol.Connection` — one process per peer, either
    role (`:agent` or `:client`), bidirectional request correlation,
    supervised per-session processes.
  * Vendor extensions ride `_meta["raxol.io"]` and `_raxol/*` methods:
    resumable sessions over an in-memory journal (offset-based
    reattach/replay), capability tokens, and taint annotation.

Protocol version: integer `1` (the stable ACP v1 surface).

# `protocol_version`

```elixir
@spec protocol_version() :: pos_integer()
```

The ACP protocol version this library implements (an integer, per spec).
