OpenCode 进程保留在 server 本地（agent 域） - 所有文件/shell 工具调用通过 MCP bridge 转发到 SCF 沙箱（sandbox 域） - OpenCode 内置 read/write/bash/edit 工具**被禁用**，LLM 只能用 sbx_* 工具 ## 架构 ``` opencode acp (server 本地) │ ├─ 内置 read/write/bash/edit (已禁用) │ └─ MCP client ─stdio─► sandbox-mcp-bridge.js (子进程) │ └─ HTTP ─► SCF /api/tools/{read,write,bash,...} → 沙箱隔离目录 /tmp/workspace// ``` ## 实现 ### 新增 - src/agent/runtime/sandbox-mcp-bridge.ts 独立进程，MCP stdio server + 沙箱 HTTP 桥接。 暴露 read/write/edit/bash/glob/grep 6 个工具。 沙箱凭证通过 env 注入。 tsup 单独 build 成 dist/agent/runtime/sandbox-mcp-bridge.js。 - src/agent/runtime/opencode-session-config.ts per-session 临时工作目录 + 生成 opencode.json： - agent.sandboxed.tools = { read:false,…, sbx_*:true } - mcp.sbx = { command: [node, bridge.js], env: {…} } - AGENTS.md 明确告诉 LLM 用 sbx_* 相对路径 - src/agent/runtime/acp-transport.ts stdio transport 工厂抽象（当前只有 local-stdio） - scripts/test-opencode-sandbox-e2e.mts 完整沙箱隔离 e2e： 让 LLM 用 sbx_write 写文件 → 独立调沙箱 read 验证 → 确认本地未被污染 ### 改动 - src/agent/runtime/opencode-acp-runtime.ts 引入 sandbox-aware 启动流程：getOrCreate sandbox → 生成 per-session config → spawn opencode → setSessionMode('sandboxed') → prompt - package.json + @modelcontextprotocol/sdk build 脚本加 sandbox-mcp-bridge.ts（ESM 单文件） ## 关键发现（已处理） 1. OpenCode 的 ACP agent 不发 fs/* / terminal/* client 回调（所有内置工具本地执行） → 所以 ACP client 回调方向不可行，必须用 MCP 注入 2. OpenCode 支持 per-agent `tools: { name: boolean }` 配置禁用内置工具 3. OpenCode MCP 工具名会自动加 _ 前缀（server='sbx' → sbx_read/sbx_write） 4. 当前沙箱 /api/tools/{read,write,...} 拒绝所有绝对路径（403 Path traversal blocked） 只接受相对路径 → AGENTS.md 已注明 ## 验证结果 ### e2e#4 沙箱隔离（真实 SCF 环境） ``` [tool_use ▶] name=sbx_write [tool_result ◯] out="Wrote file successfully." sandbox file content = "1: hello from sandbox i24jd6en" ← 沙箱里真的写入 local /tmp/hello-sandbox-...txt exists = false ← 本地未被污染 used sbx_* tools: PASS (count=1) did NOT use builtin tools: PASS (count=0) sandbox file has expected: PASS local NOT polluted: PASS OVERALL: PASS ``` ### 回归 - e2e#1 (本地模式) PASS — 无 envId 时自动退回，不禁用内置工具 - e2e#2 (HTTP 公开端点) PASS - e2e#3 (HTTP SSE chat) PASS - type-check / lint / build / format 全通过 ##

OpenCode 扫描 `~/.config/opencode/tools/*.ts` 作为 custom tools， **同名 custom tool 覆盖 builtin**（文档承诺 + 日志观察均已证实）。 2. OpenCode 原生支持 .ts 文件（zod 作为它自己的依赖已打包）。 但 tsup 编译后的 .js 文件保留 `import 'zod'` 静态语句，当前 opencode binary 无法解析这种外部 import，会静默忽略。所以 installer 直接拷 .ts 源文件。 3. OpenCode 的 MCP / tool 子进程继承父 opencode 进程的 process.env (源码 packages/opencode/src/mcp/index.ts: `env: { ...process.env, ... }`)。 → 我们 spawn opencode 时注入的 env 能传到工具执行处。 ## 改动 ### 新增 - src/agent/runtime/opencode-installer.ts 幂等安装 6 个工具模板到 ~/.config/opencode/tools/。 hash 比对跳过未变更；OPENCODE_TOOLS_FORCE_REINSTALL=1 强制覆盖。 - src/agent/runtime/opencode-tool-templates/ {read, write, edit, bash, grep, glob}.ts — 每个文件独立自包含： if (SANDBOX_MODE === '1') → fetch SANDBOX_BASE_URL/api/tools/* else → 本地 fs / child_process ### 重写 - src/agent/runtime/opencode-acp-runtime.ts 每次 chatStream： 1. ensureToolsInstalledOnce() — 惰性安装 2. scfSandboxManager.getOrCreate(convId, envId) 3. spawn opencode acp, env={ SANDBOX_MODE:'1', SANDBOX_BASE_URL, SANDBOX_AUTH_HEADERS_JSON, } 4. ACP 握手 → newSession → prompt 删除 setSessionMode / mcpServers / 临时目录写 opencode.json 等旧逻辑 ### 删除 - sandbox-mcp-bridge.ts（MCP 子进程中转层） - opencode-session-config.ts（per-session 配置写入） ## 测试结果 ### e2e#1 本地模式 ``` [tool_result ◯] out="Wrote 18 bytes to /tmp/opencode-runtime-e2e/hello.txt" ^^^^^^^^^^^^^ 这是 custom write.ts 的输出格式 OVERALL: PASS ``` ### e2e#4 沙箱隔离（真实 SCF） ``` [tool_use ▶] name=write ← LLM 用 write 工具（不是 sbx_write） [tool_result] out="{path: /tmp/workspace/huming-test-.../sandbox-e2e-v2-.../...txt, bytesWritten: 22, diff: ...}" ← 沙箱 HTTP API 响应格式 sandbox file content = "1: hello from v2 vusknorg" ← 独立调沙箱 read 验证 local /tmp/.../txt exists = false ← 本地干净 LLM used 'write' tool: PASS sandbox file has content: PASS local NOT polluted: PASS OVERALL: PASS ``` ### 其他回归 - e2e#2 HTTP /runtimes: PASS - e2e#3 HTTP SSE chat: PASS (28 events) - type-check / lint / build / format 全通过 ## 优势对比（相比 MCP bridge 方案） - 工具名 `read/write/bash/edit` 与 LLM 训练期望一致（不用 sbx_ 前缀） - 少一个 MCP 子进程 + 一层 JSON-RPC 序列化 -

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 背景：和 Tencent SDK 的对齐审视 用户提问："这个持久化和之前的 ToolConfirm/AskUser 能力能对应吗？" 深度调研 Tencent SDK 持久化链路后发现： 我之前只在 tool_result 时 flushToDb。问题： - AskUserQuestion / ToolConfirm 场景，tool_call 发出后会挂起等待用户答复 - 挂起期间 DB 里 assistant record 是空的 parts（flushToDb 还没触发） - 前端此时若打开历史，看不到"系统在问你问题"的卡片 Tencent 不受此影响：它通过 SDK JSONL 写 + updateToolResult 立刻同步； OpenCode 走事件流，需要主动在 tool_use 时触发 flush。 实测 opencode 事件顺序（test-event-order.mjs）： tool_call (status=pending) ← 工具调用，execute 即将开始 [execute 阻塞等用户答复] tool_update (status=completed, rawOutput=...) ← execute 返回 所以 tool_use 是挂起前的"最后一个可见事件"，必须立刻 flush。 ## 改动 opencode-acp-runtime.ts makeEmitter: if (msg.type === 'tool_use' || msg.type === 'tool_result') { messageBuilder.flushToDb().catch(...) } ## 验证 新增 scripts/test-persistence-suspend-e2e.mts： Round 1: LLM 调 AskUserQuestion → 等 ask_user 事件 ★ 挂起期间 loadDBMessages： assistant status=pending parts=[text, tool_call(in_progress)] 无 tool_result ← 预期行为（还没答） Round 2: askAnswers 恢复 → 最终 loadDBMessages： assistant status=done parts=[text, tool_call(completed), tool_result(completed), text(继续)] 所有断言 PASS。 ## 额外：关于 Tencent 独有的持久化步骤 调研发现 Tencent SDK 还做： - providerData 继承（从原 tool_call 继承 messageId/model/agent） - providerData 清理（剥离 SDK 的 skipRun/error deny 标记） - Resume 时立刻同步调 updateToolResult 这些是 Claude SDK 的 JSONL 行为兼容需要的（防 deny 死循环）。 OpenCode 不走 JSONL，通过事件流自然同步 tool_result，没有这些兼容性压力。 所以"不实现"是正确的设计简化，文档 §14.10 明确记录了这点。 ## 回归 e2e #1 local + ToolConfirm + Persistence 全 PASS type-check / lint / build /

exclude __tests__ 目录（不参与 server tsc 编译）。 baseline 1 个测试验证配置正确。 ## 优化 2：buildHistoryContextPrompt 格式改进（优化2，借鉴 open-design server.ts） 旧格式： User: 你好 (tool_call: AskUserQuestion {"questions":[...]}) ← JSON 截到 200 字符可能断截 新格式（Markdown 分层，turn 编号，安全截断）： ## Turn 1 **User:** 你好 **Assistant:** 很好！ [Tool call] AskUserQuestion params: question, header, options ← 只有参数名，无参数值（不会断截） [Tool result] AskUserQuestion — completed (32 bytes) ← 只有摘要，无原始内容 --- ## Current user message 单元测试 16 个（buildHistoryContextPrompt.test.ts）： 空历史/envId空/全排除/DB异常 → fallback 到原 prompt turn 编号/Markdown 前缀/--- 分隔 tool_call 安全截断（含参数名、不含参数值） tool_result 摘要（name + status + bytes） reasoning 跳过 / pending record 跳过 / excludeRecordIds e2e 验证：test-opencode-runtime.mts PASS + memory-flow LLM 正确记住名字/工具/答案。 ## 优化 3：fallbackBins + resolveOnPath（优化1，借鉴 open-design agents.ts） 统一 bin 解析，消除两份独立常量（acp-transport 和 runtime 各自的 OPENCODE_BIN）： - 新增 resolveOnPath(bin)：同步 existsSync，无子进程 - 新增 getResolvedBin()：模块级缓存；fallback 顺序： OPENCODE_BIN env → 'opencode' → 'opencode-ai' - 删除 runtime 的独立 OPENCODE_BIN 常量 - isAvailable() 改为 getResolvedBin() !== null（同步，快） - spawnLocalOpencode 用 getResolvedBin()；找不到时友好错误信息 单元测试 10 个（resolveOnPath.test.ts）： vi.mock('node:fs') + vi.stubEnv 控制 PATH/OPENCODE_BIN PATH 找到/找不到/空 PATH / OPENCODE_BIN env override(存在/不存在) / fallback chain / isAvailable true/false e2e 验证：test-opencode-runtime.mts PASS（spawn 不 break） ## 测试汇总 vitest 单元测试：27 passed - baseline: 1 - buildHistoryContextPrompt: 16 - resolveOnPath: 10 e2e: test-opencode-runtime PASS

opencode-acp（OpenCode ACP） - 未来可扩展接入更多 runtime ## 改动 ### 前端（零感知降级：< 2 个 runtime 时不显示） task-form.tsx: - TaskFormProps.onSubmit 加 selectedRuntime?: string - useEffect 动态 fetch GET /api/agent/runtimes； < 2 个 available runtime → 不渲染选择器（零感知） - runtime Select 复用 model Select 完全一样的样式（h-7 border-0 text-sm） - 插在 "model · runtime" 行，用 · 分隔 - RUNTIME_LABELS 映射（tencent-sdk → "CodeBuddy (Default)", opencode-acp → "OpenCode ACP"） home-page-content.tsx: - handleTaskSubmit 类型加 selectedRuntime?: string - 所有 fetch('/api/tasks', ...) body 透传 selectedRuntime（含 multi-repo + multi-agent 路径） ### 后端 db/types.ts: - Task interface 加 selectedRuntime: string | null - TaskNullableFields 加 'selectedRuntime' db/schema.ts (drizzle sqlite, dev mode): - tasks table 加 selectedRuntime text 列（注释 null = registry default） db/cloudbase/repositories.ts: - normalizeTask 加 selectedRuntime: doc.selectedRuntime ?? null - create 默认 selectedRuntime: null routes/tasks.ts: - 接收 body.selectedRuntime 保存到 DB routes/acp.ts / handleSessionPrompt: - 两次 DB 查询合并成一次（减少 I/O） - 读 task.selectedRuntime 传给 agentRuntimeRegistry.resolve() - 优先级：request params.runtime > task.selectedRuntime > AGENT_RUNTIME env > default ## UI 行为 - 只有 1 个 runtime 时：完全不显示（不影响现有用户体验） - 有多个 runtime 时：模型选择器后显示 · + runtime Select ``` [CodeBuddy · GLM 5.1 · CodeBuddy (Default)▾] ``` - 用户选择后随任务一起保存，重新发消息沿用选中的 runtime - selectedRuntime = '' 或 null 时 registry 按 default 规则选 ## 测试 unit tests: 27/27 PASS lint: PASS server tsc: PASS web tsc: PASS build:server + build:web: PASS --- .../buildHistoryContextPrompt.test.ts | 11 +---

=?UTF-8?q?fix(agent):=20tool=20override=20schema=20?= =?UTF-8?q?=E5=AE=8C=E5=85=A8=E5=AF=B9=E9=BD=90=20opencode=20builtin=20(v1?= =?UTF-8?q?.14.33)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 问题 opencode tool override 模板（opencode-tool-templates/*.ts）的参数名和 语义与 opencode builtin tool 不一致，导致 LLM 按 builtin 训练记忆传参时 匹配失败： - read/write/edit：builtin 用 filePath，我们用 path → LLM 传错参数名 - read：builtin offset 1-indexed，我们 0-based → 行偏移错误 - bash：builtin 有 workdir、description 参数，我们没有 - grep：builtin 参数名 include，我们用 glob → 字段名不一致 ## 修复 所有 6 个 builtin override 文件（read/write/edit/bash/grep/glob） schema 完全对齐 opencode v1.14.33 src/tool/*.ts： read: filePath（非 path）; offset 1-indexed; 保留 limit write: filePath（非 path）; content 语义一致 edit: filePath（非 path）; oldString/newString/replaceAll 语义一致 bash: +workdir; +description; timeout 默认 120000ms（原 60000） grep: include（非 glob）; 参数名对齐；内部转换到沙箱 API 的 glob 参数 glob: pattern/path 语义一致 沙箱模式内部仍正常转发到 SCF，filePath 按相对路径传给沙箱 API。 ## 可维护性：版本锁定 + 漂移检测 每个文件顶部加注释： // Schema 与 opencode builtin 完全对齐（v1.14.33 src/tool/xxx.ts） 新增 scripts/check-tool-schemas.mts + package.json check:tool-schemas 脚本： - 对比本地 opencode --version 与模板注释里的版本 - 不一致时报警（exit 1），提醒人工对比上游变更并同步 - 运行：pnpm check:tool-schemas AskUserQuestion.ts 标注为 custom tool（非 builtin override），不参与 版本比较；注明 schema 来源是 Tencent AskUserQuestionData 契约。

File and line citations below are against that branch. +> +> **TL;DR**: OpenCode's `acp` command is **not** a thin ACP agent that delegates I/O to the client. It boots the full OpenCode runtime (HTTP server + internal tool registry + filesystem + shell) inside the same process and exposes a JSON-RPC façade over stdio. Builtin tools (`read`, `write`, `edit`, `bash`, `grep`, `glob`, `webfetch`, …) execute locally against the *agent's* filesystem/shell. The ACP `connection.*` callbacks are used only for **presentation** (streaming `session/update` notifications, `session/request_permission`), and — in one narrow case — `fs/write_text_file` is called to push the post-approval edit back to the editor. `fs/read_text_file`, `terminal/*`, `fs/write_text_file` for arbitrary tool writes are **not** consumed. + +--- + +## 1. 启动与传输 + +| Item | Value | Source | +| --- | --- | --- | +| CLI entry | `opencode acp` (registered via yargs `cmd`) | `packages/opencode/src/cli/cmd/acp.ts:12-21` | +| Working directory flag | `--cwd` (defaults to `process.cwd()`) | `packages/opencode/src/cli/cmd/acp.ts:16-20` | +| Transport | NDJSON over stdio (`ndJsonStream` from `@agentclientprotocol/sdk`). **Not** LSP-style `Content-Length` framing. | `packages/opencode/src/cli/cmd/acp.ts:4, 55` | +| Stream wiring | `process.stdout` → `WritableStream`, `process.stdin` → `ReadableStream`, glued via `ndJsonStream`, then an `AgentSideConnection` is constructed | `packages/opencode/src/cli/cmd/acp.ts:32-60` | +| Lifecycle | Blocks on `process.stdin` `end`/`error`; no heartbeat/reconnect logic | `packages/opencode/src/cli/cmd/acp.ts:63-67` | +| Sidecar HTTP server | `Server.listen()` is started **inside the acp process** at `127.0.0.1:` (port 0) *before* stdio transport is wired; `createOpencodeClient` is then used by the ACP agent to talk to itself via localhost HTTP. | `packages/opencode/src/cli/cmd/acp.ts:24-30`, `packages/opencode/src/cli/network.ts:6-15, 44-62` | +| Server auth | HTTP Basic via `OPENCODE_SERVER_USERNAME` / `OPENCODE_SERVER_PASSWORD`.

From reading tool files and `permission/index.ts`: + +- `edit`, `write`, `apply_patch` → permission name **`edit`** (grouped by `EDIT_TOOLS = ["edit","write","apply_patch"]` in permission/index). +- `bash` → permission name **`bash`** (request triggered from `tool/bash.ts`). +- `webfetch` → permission name **`webfetch`**. +- Other tools (`read`, `grep`, `glob`, `lsp`, `todo`, `task`, `plan`, `skill`, `question`, `websearch`) do **not** request permission in current code. +- MCP tools: permission name equals the tool id (generic fallback in `Permission.disabled()`). + +### Permission options advertised + +```ts +[ + { optionId: "once", kind: "allow_once", name: "Allow once" }, + { optionId: "always", kind: "allow_always", name: "Always allow" }, + { optionId: "reject", kind: "reject_once", name: "Reject" }, +] +``` +Source: `packages/opencode/src/acp/agent.ts:150-154`. + +### Configurable? + +Yes — OpenCode's own `opencode.json` / config supports a `permission` ruleset (`Schema.Array(Rule)` in `permission/index.ts`) that evaluates `{ permission, pattern, action: "allow"|"deny"|"ask" }` against the tool call, **before** the ACP round-trip. If a pattern `allow`s, the client is never asked. If it `deny`s, the tool fails with `DeniedError`. See `permission/evaluate.ts` and `permission/arity.ts` (not read in full, but referenced from `index.ts`). + +### Post-approval side effect (important) + +After the user approves an `edit`, the agent re-reads the original file, applies the stored unified diff via `diff.applyPatch`, and pushes the result to the client via `connection.writeTextFile`. Source: `packages/opencode/src/acp/agent.ts:239-253`. **If the client supports `fs/write_text_file` this shows up as a duplicate write**; the real write will also happen inside `WriteTool`/`EditTool` through `AppFileSystem.Service`. + +--- + +## 7. Session 管理 + +| Topic | Answer | +| --- | --- | +| ACP session registry | In-memory `Map` in `ACPSessionManager` (`packages/opencode/src/acp/session.ts:8-14`). One instance per `Agent`. | +| Backing store | `sdk.session.create` / `sdk.session.get` over the internal HTTP server (`packages/opencode/src/acp/session.ts:20-75`). The *actual* session persistence is OpenCode's own DB (SQLite / JSONL depending on build) — ACP just keeps a shallow in-mem map for CWD / MCP / model / variant / mode. | +| Multi-session per process | Yes — no `1:1` constraint. The ACP `Agent` instance holds all sessions. Event pump is a single loop shared by all sessions; events are dispatched by `part.sessionID`. | +| `session/load` | **Implemented** (`agent.ts:619-687`) — re-creates ACP state, replays the full message history as `session/update` notifications. README claims this is "basic support" / "doesn't restore actual conversation history", but the code does replay. | +| `session/list` | Implemented with cursor (`agent.ts:689-732`). | +| `session/fork` | Implemented as `unstable_forkSession` (`agent.ts:734-797`). Creates a divergent copy and replays history. | +| `session/resume` | Implemented as `unstable_resumeSession` (`agent.ts:799-828`). No replay. | +| `session/cancel` | Implemented (`agent.ts:1538-1547`) → `sdk.session.abort`. | +| Concurrent prompts in one session | `cancel` + permission queueing are the only concurrency controls; there's nothing preventing overlapping `prompt()` calls hitting `sdk.session.prompt` — OpenCode's server presumably serialises internally (not verified here). | + +--- + +## 8. 配置 / 认证 + +### Config resolution + +ACP mode **does** read OpenCode's configuration. `bootstrap(process.cwd(), ...)` in `acp.ts` initialises the full app runtime, which loads `opencode.json` / `.opencode/` config via `Config.Service`. Then `sdk.config.get({ directory })` is used at the per-request level so `--cwd` (or per-session `cwd`) picks up project-local config (`agent.ts:1601-1611`). + +### Default model selection + +`defaultModel()` at `packages/opencode/src/acp/agent.ts:1594-1654`: +1. If `ACPConfig.defaultModel` is set, use it. (It's never set — `ACP.init({ sdk })` at `acp.ts:56` passes no default.) +2. Read `config.model` from the resolved config. +3. Else enumerate `providers`, prefer `opencode` provider's `big-pickle`, else sort all models via `Provider.sort` and pick the first. +4. Fallback: `{ providerID: "opencode", modelID: "big-pickle" }`. + +### Dynamic model / variant / mode switching + +- Models: `session/set_model` (`setSessionModel`) — `agent.ts:1286-1306`. Accepts `"provider/model"` or `"provider/model/variant"`. +- Modes (OpenCode "agents"): `session/set_mode` — `agent.ts:1308-1315`. Validates against `AgentModule`'s list of non-hidden, non-subagent agents. +- `session/set_config_option` accepts `{ configId: "model" | "mode", value }` — `agent.ts:1317-1353`. +- Per-prompt `model` is **not** accepted as an ACP parameter; callers must call `session/set_model` before `session/prompt`. But `prompt()` does fall back to the session's current model (`agent.ts:1360-1364`). + +### Authentication + +- `initialize()` advertises one auth method `{ id: "opencode-login", ... }`, optionally with a `terminal-auth` `_meta` so clients can offer a CLI-launch button (`agent.ts:537-552`). +- `authenticate()` **throws `"Authentication not implemented"`** (`agent.ts:580-582`). This means ACP clients must either: + - Rely on pre-existing OpenCode auth (user already ran `opencode auth login` locally so credentials exist under `~/.config/opencode`), OR + - Ship API keys via env (`ANTHROPIC_API_KEY` etc.) at spawn time. +- Per-session `LoadAPIKeyError` is caught and converted to `RequestError.authRequired()` in `newSession`/`loadSession`/`forkSession`/`resumeSession` (`agent.ts:608-616`, `:678-686`, `:788-796`, `:819-827`). +- `OPENCODE_API_KEY` is **not referenced in the ACP code path** — it's an OpenCode Zen / "opencode" provider key, consumed by `Provider` modules. Standard AI-SDK env vars (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, …) work as usual because tools instantiate the AI SDK providers in-process. + +### HTTP server auth (for the sidecar) + +`OPENCODE_SERVER_PASSWORD` / `OPENCODE_SERVER_USERNAME` via Basic Auth. Unset by default → loopback only. See `packages/opencode/src/server/middleware.ts`. + +--- + +## 9. 限制与已知问题 + +### From the in-repo README (`packages/opencode/src/acp/README.md`) + +> The README is **stale**. It references `client.ts` and `server.ts`, which don't exist in the current `src/acp/` directory (only `agent.ts`, `session.ts`, `types.ts`, `README.md`). Treat the README as aspirational; trust `agent.ts` as ground truth. + +Items the README lists as "Not Yet Implemented": +- Streaming responses → **Now implemented** (`message.part.delta` → `agent_message_chunk` / `agent_thought_chunk`). +- Tool call reporting → **Now implemented** (see §5.3). +- Session modes → **Now implemented** (`setSessionMode`). +- Terminal support → **Still not plumbed to ACP**; bash runs locally. +- Session persistence via `session/load` → **Implemented**, but tied to OpenCode's own storage. + +### From GitHub issues / PRs (as of 2026-05-01, ranked by recency) + +| # | Type | State | Summary | +| --- | --- | --- | --- | +| #24846 | Issue | open | `session/new` reported as "Method not found", `authenticate` returns "not implemented".

If it crashes, all sessions lose updates; the while-loop auto-reconnects (`agent.ts:173-188`) unless aborted. +- **`_meta` protocol extension**: OpenCode embeds a namespace `_meta: { opencode: { modelId, variant, availableVariants } }` in responses — clients not understanding the namespace can ignore it (`agent.ts:1760-1772`). +- **Slash commands intercepted in `prompt()`**: any user message starting with `/` is parsed and routed either to `sdk.session.command` or (for `compact`) `sdk.session.summarize`. Be aware this subverts normal prompting (`agent.ts:1443-1528`). + +### Things I couldn't verify from source alone + +- Whether the `@agentclientprotocol/sdk@0.16.1` SDK implements any client→agent streaming backpressure. Not relevant for implementing a client, but matters for throughput tuning. +- Exact behaviour when multiple parallel `session/prompt` calls target the same `sessionId`. No explicit guard in ACP code; would have to read `packages/opencode/src/session/session.ts`. +- Whether `session/cancel` is idempotent across repeated calls (not verified). + +--- + +## 10. 集成建议（给想写 ACP client 的人） + +1. **Transport**: Speak NDJSON, not LSP-style. Line-delimited JSON frames. `stdin` writes → agent, `stdout` reads ← agent. Everything you emit must be `\n`-terminated single-line JSON. +2. **Capability negotiation**: Advertise `fs.readTextFile: false, fs.writeTextFile: true` (OpenCode only ever *writes* to you, for the post-approval edit refresh). You do **not** need terminal capabilities — OpenCode will never call them. Advertising them is harmless. +3. **Do not assume the client owns the filesystem**. OpenCode will mutate files under `--cwd` on its own. If you need sandboxing, do it at spawn time (container, chroot, dedicated worktree). `--cwd` is the only knob you control. +4. **Auth**: Don't rely on `authenticate`. Two workable paths: + - Spawn `opencode auth login` yourself (the `terminal-auth` `_meta` capability on `authMethods` is designed for this). + - Provide provider API keys via env (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, …) or via a pre-populated config file. +5. **Model selection**: Call `session/set_model` after `session/new` if you want a specific model; don't put it in `session/prompt` (not a protocol field, and ignored by OpenCode). `variant` rides on the `modelId` as a third path segment (`provider/model/variant`). +6. **Session routing**: Single `opencode acp` process handles multiple sessions concurrently. Reuse the process; spin a new one only if you need a different auth/env surface. +7. **Streaming**: Subscribe to `session/update` for: + - `agent_message_chunk`, `agent_thought_chunk` — text stream + - `tool_call` + `tool_call_update` — tool timeline (rich enough to render: inputs, outputs, `content`/`diff` blocks, `rawInput`/`rawOutput`) + - `plan` — todowrite plans + - `usage_update` — token/cost meter + - `available_commands_update` — slash command palette (arrives shortly after `session/new`, via `setTimeout(0)` at `agent.ts:1256-1264`) + - `user_message_chunk` (replay only — live user parts are skipped at `agent.ts:459-464`) +8. **Permission UX**: Treat `session/request_permission` as user-facing and blocking. OpenCode serialises per-session, so one prompt at a time, but per-process you can get concurrent prompts across sessions. +9. **Image support**: Base64 data URLs and `http://` URIs work today; `https://` does **not** (issue #24815 open). Safest: pre-fetch and embed as `data:`. +10. **Slash commands**: If you implement your own `/foo` UI, remember OpenCode also interprets leading `/` in the text. Either strip the `/` before sending, or lean on OpenCode's command registry (`sdk.command.list` via `available_commands_update`). +11. **Error semantics**: Model/auth failures surface as JSON-RPC `RequestError.authRequired()`. Fatal tool errors arrive as `tool_call_update` with `status: "failed"` — they are *not* JSON-RPC errors and the `prompt()` call will still resolve with `stopReason: "end_turn"`. +12. **`OPENCODE_ENABLE_QUESTION_TOOL=1`**: Set this *only* if your client can respond to `QuestionTool` prompts (which currently also route through `permission.asked` / `session/request_permission` — verify in `packages/opencode/src/tool/question.ts` before shipping). + +--- + +## 11. 源码文件引用（汇总） + +- CLI entry: `packages/opencode/src/cli/cmd/acp.ts:12-70` +- Network defaults (sidecar HTTP): `packages/opencode/src/cli/network.ts:6-15, 44-62` +- Main ACP agent: `packages/opencode/src/acp/agent.ts:132-1548` +- Agent `initialize`: `packages/opencode/src/acp/agent.ts:534-578` +- Agent capabilities advertised: `packages/opencode/src/acp/agent.ts:556-571` +- Agent `authenticate` (not implemented): `packages/opencode/src/acp/agent.ts:580-582` +- Agent `newSession`: `packages/opencode/src/acp/agent.ts:584-617` +- Agent `loadSession` (with replay): `packages/opencode/src/acp/agent.ts:619-687` +- Agent `prompt` (command intercept + sdk.session.prompt): `packages/opencode/src/acp/agent.ts:1355-1536` +- Agent `cancel`: `packages/opencode/src/acp/agent.ts:1538-1547` +- Event subscription (bus → session/update): `packages/opencode/src/acp/agent.ts:164-188, 190-532` +- Permission handling (bus → request_permission → reply): `packages/opencode/src/acp/agent.ts:192-270` +- Post-approval `connection.writeTextFile` call (the ONLY fs callback): `packages/opencode/src/acp/agent.ts:239-253` +- Tool→ACP kind mapping: `packages/opencode/src/acp/agent.ts:1550-1592` +- Default model selection: `packages/opencode/src/acp/agent.ts:1594-1654` +- Session manager: `packages/opencode/src/acp/session.ts:1-115` +- ACP types: `packages/opencode/src/acp/types.ts:1-24` +- Stale internal README: `packages/opencode/src/acp/README.md` +- Tool registry (proves tools are local): `packages/opencode/src/tool/registry.ts:1-200` +- Local-fs read path: `packages/opencode/src/tool/read.ts` +- Local-fs write path: `packages/opencode/src/tool/write.ts` +- Local-process shell path: `packages/opencode/src/tool/bash.ts` +- Permission service (bus, rules, reply): `packages/opencode/src/permission/index.ts` +- HTTP auth middleware (Basic): `packages/opencode/src/server/middleware.ts` +- SDK version & deps: `packages/opencode/package.json` + +--- + +## Bottom-line recommendation + +If the value proposition you need is **"the client owns the filesystem and terminal; OpenCode only decides what to do"**, OpenCode ACP is **not** a good fit today.
