ui/ — editor/client integration surfaces
Integrations that expose the agent to an external editor or client. These are product packages: a real surface a user drives the harness through.
| Package | Role | ctx key |
|---|---|---|
acp/ |
Agent Client Protocol bridge: serves the agent to an ACP editor (Zed) over JSON-RPC stdio | (drives ctx.agents/ctx.sessions) |
user-approval/ |
One-shot user-approval mechanism, closed outcome vocabulary, audit events, and per-session approval policy | ctx.approval |
permission/ |
User-facing permission presets (workspace-write/danger-full-access): one product-level select bundling the sandbox-mode and approval-policy knobs, written through to their session events |
ctx.permission |
user-interaction/ |
Abstract human question/answer seam used by UI-backed confirmation tools | ctx.userInteraction |
tool-ask-user/ |
Model-facing ask_user_question tool over ctx.userInteraction |
(registers on ctx.tools) |
stdio-agent/ |
Terminal stdio chat APP: the agent-core spine + console logger + readline UI + a pre-created main agent, with a bin |
(composition + bin) |
acp-agent/ |
ACP server APP: the agent-core spine + JSONL persistence + the acp bridge (no stdout logger), with a bin |
(composition + bin) |
jsonrpc/ |
Stdio JSON-RPC server for out-of-process SDK clients | (drives ctx.agents) |
jsonrpc-agent/ |
Bin-only SDK runtime app that boots an external cordis.yml |
(bin only) |
app-boot/ |
Shared boot glue for the app bins: .env loading, fail-loud Loader guards, snapshot-aware config resolution, the settle-the-tree boot sequence |
(library for the bins) |
A UI integration is a client-driver plugin, not a loop change or capability seam: it consumes the existing agent/* events and dsh-agent factory. jsonrpc is the SDK-client sibling of the acp editor bridge. The readline UI lives inside stdio-agent/ because it is scaffolding for that front door, not an independently swappable integration.
user-approval, user-interaction, and tool-ask-user live here because asking a human is a UI-backed product affordance, not part of the providerless core spine. user-approval owns the one-shot ctx.approval decision mechanism and its policy tier; answerers remain with their UI channel owners. user-interaction remains provider-neutral (ctx.userInteraction), while tool-ask-user is its model-facing consumer and the app/bridge packages provide concrete providers.
stdio-agent and acp-agent compose the agent-core spine with their front-door plugins and own their boot bins; a leaf cordis.yml supplies backends and optional tools. jsonrpc-agent is bin-only because its external config also chooses the serving jsonrpc plugin. Each lives in ui/ as a user-facing front door whose artifact owns its stdout policy.
