README

Solid Agent

**Status:** Early draft — open for discussion. Pre-alpha; no published gem yet.

**Solid Agent** is an open protocol — built on top of the [Agent Client Protocol (ACP)](https://agentclientprotocol.com/) — that wraps coding-agent SDKs and sandbox runtimes so they compose. A Ruby reference implementation ships alongside the spec.

SolidAgent.run('add tests for the auth module', agent: :claude, sandbox: :e2b)

The protocol specifies how to wrap an agent SDK so it speaks ACP, how to wrap a sandbox SDK so it fulfils ACP's client-side methods (`fs/*`, `terminal/*`), and adds a small set of runtime lifecycle methods (`runtime/snapshot`, `runtime/pause`, `runtime/resume`, `runtime/manifest_apply`) that ACP does not yet specify.

Why this exists

Coding-agent SDKs and sandbox runtimes have proliferated. Composing them by hand for every project means re-writing the same glue — translating between each SDK's native event vocabulary and ACP-shaped messages, bridging the agent CLI's stdio through whichever sandbox you picked, handling reconnection, snapshots, and so on.

Solid Agent puts that glue in one place. The protocol is small (ACP + four runtime lifecycle methods + a manifest); the refe
