From a22045be90f90640cbbeb12195c728bf29ee5b4c Mon Sep 17 00:00:00 2001 From: Gustavo Schneiter Date: Sun, 6 Sep 2026 17:46:15 -0300 Subject: [PATCH 1/5] refactor(opencode): lazy-load CLI commands to cut startup cost The entrypoint statically imported every command module (server, session, sdk, config schemas) at process start, costing tens of seconds and ~200MB RSS even for fast paths like --version. Register commands through a delegating module that only loads the real implementation when yargs parses an invocation that exercises it. Measured: --version instructions 10.4B -> 5.6B (-46%), peak RSS 224MB -> 132MB (-41%), user CPU 3.4s -> 1.9s (-44%). Also decouple UI.cancelled-error from the effect import so the ui module loads without pulling in the full effect runtime. --- packages/opencode/src/cli/cancelled-error.ts | 3 + packages/opencode/src/cli/cmd/agent.ts | 13 +-- packages/opencode/src/cli/cmd/export.ts | 3 +- .../opencode/src/cli/cmd/github.handler.ts | 11 +-- packages/opencode/src/cli/cmd/mcp.ts | 25 +++--- packages/opencode/src/cli/cmd/providers.ts | 3 +- packages/opencode/src/cli/lazy-command.ts | 43 +++++++++ packages/opencode/src/cli/ui.ts | 3 - packages/opencode/src/index.ts | 90 ++++++++----------- packages/opencode/test/cli/error.test.ts | 4 +- 10 files changed, 115 insertions(+), 83 deletions(-) create mode 100644 packages/opencode/src/cli/cancelled-error.ts create mode 100644 packages/opencode/src/cli/lazy-command.ts diff --git a/packages/opencode/src/cli/cancelled-error.ts b/packages/opencode/src/cli/cancelled-error.ts new file mode 100644 index 000000000000..11a4f821a6dc --- /dev/null +++ b/packages/opencode/src/cli/cancelled-error.ts @@ -0,0 +1,3 @@ +import { Schema } from "effect" + +export class CancelledError extends Schema.TaggedErrorClass()("UICancelledError", {}) {} \ No newline at end of file diff --git a/packages/opencode/src/cli/cmd/agent.ts b/packages/opencode/src/cli/cmd/agent.ts index c9c1d2c1670f..a1f0f1ee1580 100644 --- a/packages/opencode/src/cli/cmd/agent.ts +++ b/packages/opencode/src/cli/cmd/agent.ts @@ -1,6 +1,7 @@ import { cmd } from "./cmd" import * as prompts from "@clack/prompts" import { UI } from "../ui" +import { CancelledError } from "../cancelled-error" import { Global } from "@opencode-ai/core/global" import path from "path" import fs from "fs/promises" @@ -105,7 +106,7 @@ const AgentCreateCommand = effectCmd({ }, ], }) - if (prompts.isCancel(scopeResult)) throw new UI.CancelledError() + if (prompts.isCancel(scopeResult)) throw new CancelledError() scope = scopeResult } targetPath = path.join(scope === "global" ?

A single 23MB message re-rendered 90x wrote ~2GB of redundant JSON to the event log (the user's opencode.db grew to 7GB, 6.4GB of it the event table). The only consumer of these durable rows is the experimental workspaces sync (off by default); the local UI/SSE/projection read the projected message/part tables. Add PublishOptions.persist (default true = unchanged). updateMessage/ updatePart pass persist: experimentalWorkspaces so local installs stop appending to the event log while still projecting and notifying. With workspaces enabled the behavior is byte-identical to before. The bridge only emits sync envelopes for events carrying a durable marker, so local events are never observed by cross-instance sync. Measured: write-path E2E (90x growing part up to 24MB) 10.2s -> 5.5s (-46%); publish micro-bench -92%; durable bytes per turn 100% eliminated.
