Goal + +Build a standalone `general-agent-sdk` that: + +- uses OpenClaw's real embedded SDK seam as the internal source of truth +- preserves SDK-suitable OpenClaw capabilities instead of re-inventing them locally +- reaches the same public capability tier as Claude Agent SDK for embedded agent use cases +- excludes OpenClaw features that are not SDK concerns, especially Cron, Channel, Gateway, and related control-plane responsibilities +- is fully decoupled from VisionClaw in branding, packaging, and public API + +The target is not "an OpenClaw-flavored host adapter". The target is a general-purpose embedded agent SDK with source-synced internals. + +## 2. Product Decision + +The product is: + +- package name: `general-agent-sdk` +- public brand: `General Agent SDK` +- public symbol family: `GeneralAgent*` + +The product is not: + +- `openclaw-agent-sdk` +- a VisionClaw compatibility package +- a published `plugin-sdk` +- a repackaged OpenClaw gateway + +All published `VisionClaw` compatibility exports must be removed from this repository and package. + +## 3. Parity Target + +The acceptance bar is capability parity with Claude Agent SDK for embedded-agent scenarios, not API-shape cloning. + +The SDK must support the same solution class for most embedded agent tasks that Claude Agent SDK supports: + +- autonomous multi-step agent execution +- built-in file/code/shell/web tool usage +- custom in-process tools +- MCP tools +- approvals and user-input pauses +- resumable sessions +- hooks +- subagents +- streaming +- file checkpoints when file mutation tools are enabled + +Matching exact Anthropic terminology is not required.

Hard Non-Goals + +The following remain out of scope for the SDK: + +- gateway runtime +- channel ingress and egress +- owner notifications +- cron scheduling and cron delivery +- node host control plane +- channel-specific action routing +- `message`, `gateway`, `cron`, `nodes` +- `sessions_list`, `sessions_history`, `sessions_send` +- any VisionClaw-specific session protocol or adapter export + +These concerns may exist in upstream OpenClaw, but they are not SDK responsibilities here. + +## 5. Source-of-Truth Rule + +Implementation must follow this priority order: + +1. OpenClaw source code for the embedded runner, tool assembly, tool policies, hooks, and related SDK-suitable behavior +2. `pi-coding-agent` and pi mono source where OpenClaw's embedded path depends on them +3. `openclaw_tool_map.txt` as a secondary checklist only +4. this repository's current simplified runtime only when it does not conflict with items 1-3 + +The repository must stop treating `src/upstream/openclaw/**/*` as archival reference only. The OpenClaw-derived embedded seam must become a live internal runtime dependency. + +## 6. Architecture + +### 6.1 Public Layer + +The supported public API remains under `src/index.ts` and `src/public/*`. + +The public surface must expose only general SDK concepts: + +- SDK factory +- sessions +- stream events +- tool registration +- MCP integration +- hooks +- checkpointing +- persistence +- approvals / user-input continuation +- subagents + +The public API must not expose: + +- VisionClaw compatibility types +- OpenClaw-branded symbol names +- inert host-specific fields +- plugin-runtime leakage as a public compatibility promise + +### 6.2 Internal Runtime Layer + +The internal runtime must be reorganized around the actual OpenClaw embedded seam: + +- tool assembly +- tool policy pipeline +- pi tool adapters +- hook runner integration +- compaction +- session lifecycle +- hosted-tool continuation +- provider/model resolution relevant to SDK scope + +The current handwritten local runtime in `src/core/*` and `src/loop/*` may remain temporarily during migration, but it is not the end-state source of truth. + +### 6.3 Upstream Boundary + +The repository may still vendor only a subset of OpenClaw, but that subset must be: + +- sufficient to build the SDK runtime +- internally coherent +- compiled and tested +- provenance-tracked + +Partial vendoring that cannot compile is not acceptable. + +## 7. Naming and Packaging + +### 7.1 Required Renames + +The public surface must converge on names like: + +- `createGeneralAgentSdk` +- `GeneralAgentSdk` +- `GeneralAgentSdkOptions` +- `GeneralAgentSession` +- `GeneralAgentSessionParams` +- `GeneralAgentStreamEvent` + +Names like `GeneralAgentAgentSdk` and `GeneralAgentAgentSession` are bugs and must be removed. + +### 7.2 Package Exports + +The package must publish only general SDK exports from `.`. + +It must remove: + +- `./compat/visionclaw` +- `./plugin-sdk` + +### 7.3 Documentation Cleanup + +Repository-facing docs must stop presenting the SDK as: + +- a VisionClaw integration project +- a public OpenClaw rebrand +- a minimal toy subset with intentionally reduced scope for web and hooks + +Old docs may be archived as historical design records, but they must not remain the active source of truth. + +## 8. Tool Model + +Tools must be classified explicitly into four buckets. + +### 8.1 Core Built-In Tools + +These are required for public v1: + +- `read` +- `write` +- `edit` +- `apply_patch` +- `exec` +- `process` +- `web_search` +- `web_fetch` + +Behavior for these tools must be source-synced to OpenClaw, not implemented as simplified local substitutes. + +### 8.2 Optional Built-In Tools + +These are SDK-suitable and should be integrated when their upstream dependencies can be made coherent inside the SDK: + +- `pdf` +- `image` +- `image_generate` +- `browser` +- `canvas` +- `tts` +- `memory_get` +- `memory_search` +- `agents_list` +- `session_status` +- `sessions_spawn` +- `sessions_yield` +- `subagents` + +Optional built-ins are not required to ship all at once, but each must be explicitly tracked as: + +- implemented +- pending +- blocked by missing upstream dependency +- intentionally deferred + +### 8.3 Host-Bridged Tools + +Some capabilities may be exposed through host-provided tools instead of SDK-native built-ins when that is the correct architecture. This is acceptable only when the public behavior remains equivalent. + +### 8.4 Out-of-Scope Tools + +These remain excluded from the SDK: + +- `message` +- `gateway` +- `cron` +- `nodes` +- `sessions_list` +- `sessions_history` +- `sessions_send` + +## 9. Hook Model + +The SDK must migrate OpenClaw's hook system into the SDK runtime instead of keeping only ad hoc `beforeToolCall` / `afterToolCall` callback slots. + +### 9.1 SDK-Native Hook Events + +These hook families belong in the SDK and must be implemented natively: + +- `before_model_resolve` +- `before_prompt_build` +- `before_agent_start` +- `llm_input` +- `llm_output` +- `agent_end` +- `before_compaction` +- `after_compaction` +- `before_reset` +- `before_tool_call` +- `after_tool_call` +- `tool_result_persist` +- `before_message_write` +- `session_start` +- `session_end` +- `subagent_spawning` +- `subagent_delivery_target` +- `subagent_spawned` +- `subagent_ended` + +### 9.2 Host-Bridged Hook Events + +These may remain available through the same hook runner, but only when the host explicitly emits them: + +- `inbound_claim` +- `message_received` +- `message_sending` +- `message_sent` +- `gateway_start` +- `gateway_stop` +- `before_dispatch` + +This preserves hook portability without forcing channel/gateway responsibilities into the SDK. + +### 9.3 Hook Semantics + +The SDK must preserve upstream hook semantics where relevant: + +- modifying hooks stay ordered and merge results predictably +- blocking hooks can stop tool execution +- observation hooks remain fire-and-forget when upstream does so +- synchronous hot-path hooks stay synchronous where upstream requires that behavior + +In particular, `tool_result_persist` and `before_message_write` must preserve structured transcript mutation semantics. + +## 10. Agent Loop Requirements + +The SDK's loop must be robust enough to continue invoking tools until work is actually complete. + +### 10.1 Required Loop Behavior + +A single run must support: + +- assistant -> tool -> assistant -> tool repeated as needed +- mixed local tools, hosted tools, MCP tools, and subagents +- deterministic terminal completion +- explicit stop and abort +- interruption for approvals and user input + +### 10.2 Hosted Tool Continuation + +Hosted tool handling must be a real same-run continuation. + +It is not acceptable to: + +- emit a synthetic `tool_result` +- emit `turn_complete` +- require the host to start a logically new run + +The run must pause at the hosted-tool boundary and continue the same run when the result arrives. + +### 10.3 Structured Tool Results + +Tool results must preserve both: + +- user-visible content +- structured details payloads + +The current thin `content`-only model is insufficient for source-synced OpenClaw tools such as `web_fetch`, `pdf`, `sessions_*`, and other structured-result tools. + +### 10.4 Conversation Continuity + +The runtime must preserve message history correctly across turns in-process and across persisted resumes. + +The SDK must not rely on a message flow that drops updated loop state after a completed turn. + +### 10.5 Compaction + +Compaction must be a working runtime capability, not a timestamp placeholder. + +The SDK must: + +- detect compaction triggers +- run compaction +- emit compaction lifecycle events +- invoke compaction hooks +- preserve session integrity across retries and resumes + +## 11. Session Model + +The public session layer must support: + +- create +- continue latest +- resume by session id +- fork from existing session +- enumerate stored sessions +- read transcript / history for a stored session + +Hosted-tool suspension and approval suspension must persist enough state to survive process restart. + +## 12. Permissions, Approvals, and User Input + +The SDK must support a real control plane for: + +- allow/deny / allowlist / approval modes +- tool approval interrupts +- ask-user-question style pauses +- resume with user answer +- host-controlled policy decisions + +This must not be approximated by tool stubbing or host-side text parsing. + +## 13. MCP and Custom Tools + +The SDK must support: + +- in-process custom tools +- MCP tools from local processes +- MCP tools from HTTP endpoints + +These must compose with the same loop, event, permission, and hook systems as built-in tools. + +## 14. Subagents + +Subagents are in scope for the SDK. + +The SDK must support: + +- programmatic subagent creation +- scoped instructions +- scoped tool access +- lifecycle events and hooks +- parent/child coordination without host-specific session protocols + +Subagents are not the same as channel sessions or gateway task routing. + +## 15. Checkpointing + +If file mutation tools are enabled, the SDK must support checkpointing and rollback of agent-made file changes without requiring Git. + +Checkpointing is part of the expected embedded-agent capability tier and must be designed as a first-class SDK feature rather than a future afterthought. + +## 16. Credential and Failure Policy + +Missing required credentials must be hard errors. + +The SDK must not: + +- silently fall back to stub completions +- pretend to finish a run without a real model/tool path +- silently downgrade to a different runtime behavior + +Failure must be explicit and actionable. + +## 17. Acceptance Criteria + +The SDK is acceptable only when all of the following are true: + +1. One SDK call can start a run that autonomously executes tool/model/tool/model turns until terminal completion, host interruption, or an explicit wait-for-input boundary. +2. `web_search` and `web_fetch` ship as built-in SDK capabilities and their behavior is synchronized to OpenClaw source semantics rather than the current simplified local implementations. +3. Every SDK-suitable OpenClaw tool is explicitly classified as `core built-in`, `optional built-in`, `host-bridged`, or `out-of-scope`. +4. Hosted tools, approvals, and user-input pauses suspend and resume the same run rather than ending the turn synthetically. +5. Tool results preserve structured `details` as well as rendered content. +6. Sessions support create, continue, resume-by-id, fork, enumerate, and transcript/history access. +7. The SDK exposes a hook system covering the SDK-native hook families listed in this spec. +8. Host-bridged hook families can be emitted by the host without reintroducing channel/gateway responsibilities into the SDK. +9. MCP integration works for local-process and HTTP transports, alongside in-process custom tools. +10. Subagents are programmatic SDK features with lifecycle support and scoped tool access. +11. Streaming supports both incremental events and terminal completion semantics suitable for real-time UI consumption. +12. File checkpointing and rewind are available whenever file mutation tools are enabled. +13. Missing credentials fail loudly instead of falling back to stub behavior. +14. All VisionClaw compatibility code and exports are removed from the package. +15. All public naming is standardized on `General Agent SDK` and `GeneralAgent*`. + +## 18. Immediate Follow-Up Work + +The first implementation plan written from this spec must include: + +- removal of VisionClaw compatibility exports and tests +- public API cleanup and rename pass +- migration from simplified local web tools to source-synced OpenClaw tools +- structured tool-result model upgrade +- hosted-tool same-run continuation +- session resume/fork/list/history support +- hook runner migration +- compaction implementation +- loop robustness tests covering multi-step tool use until terminal completion +- checkpointing design and implementation + +This spec is the active source of truth for that plan.

From 0f66158c2f9053249c4437b57e78f7fb614484dd Mon Sep 17 00:00:00 2001 From: Redux0223 Date: Tue, 31 Mar 2026 19:02:54 +0800 Subject: [PATCH 4/4] =?UTF-8?q?feat:=20implement=20General=20Agent=20SDK?= =?UTF-8?q?=20source-sync=20plan=20=E2=80=94=20full=20runtime=20alignment?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete implementation of the source-sync design spec, converting the SDK from a simplified prototype into a production-ready embedded agent runtime aligned with OpenClaw's embedded seam. Major changes: Runtime & Core: - Fix multi-turn conversation memory (agent_end message accumulation bug) - Fix API key env var fallback (process.env.ANTHROPIC_API_KEY now works) - Implement working compaction runtime with truncation strategy - Replace hardcoded 200K context window with dynamic model resolution - Add transcript repair/validation for message ordering - Add restart-safe hosted-tool continuation (single + multi-tool) - Implement first-class subagent runtime with independent child sessions - Wire steering messages and follow-up messages into agent loop - Missing credentials now fail loudly (no silent stub completions) Public API: - Remove all VisionClaw compatibility code and exports - Standardize all naming on GeneralAgent* prefix - Add session lifecycle: list, resume, fork, reset, history - Add file checkpointing and rollback API - Add dynamic MCP server management (stdio + http) - Expose full 26-hook system (19 SDK-native + 7 host-bridged) Tools: - Source-sync web_search with Brave/DuckDuckGo provider runtime - Source-sync web_fetch with readability, Firecrawl, SSRF protection - Add subagents as core built-in tool (not host-bridged) - Add apply_patch tool with unified diff support - Classify all tools: core-built-in / optional / host-bridged / out-of-scope Documentation: - Complete SDK DOCS with 8 runnable examples + API reference - Update README with full feature documentation - Update plan and design spec to reflect completion status Testing: - 133 unit/integration tests passing - E2E smoke test passing - Real API E2E verified (5/5 tests pass)

Why This Spec Exists + +The current repository has a strong internal shape but does not yet define a clean public product. + +Today the codebase mixes three different intents: + +- a VisionClaw compatibility target +- an OpenClaw upstream extraction target +- a possible public SDK target + +Those goals overlap, but they are not the same product. + +The current design spec is still host-first and VisionClaw-first. It locks in requirements such as: + +- many-provider support through OpenClaw's full provider/auth stack +- plugin loading and hook execution +- VisionClaw-owned canonical session state +- a compatibility-focused boundary rather than a public developer experience + +That scope is too large for a stable public v1. + +This spec narrows the product to the minimum public shape that is worth shipping. + +## 3. Product Decision + +Public v1 will remain branded and shipped as `openclaw-agent-sdk`. + +This spec does **not** introduce a second public package name. The repository path, package name, +and public symbols must converge on `OpenClaw*` naming. Any partial `GeneralAgent*` rename work in +the current tree is treated as drift and must be cleaned up as part of this effort. + +Public v1 is defined by these decisions: + +- Runtime: Node.js `>=22.14.0` +- Module format: ESM only +- Provider support in v1: Anthropic only +- Public audience: backend services, CLIs, desktop apps, and local developer tools embedding an agent +- Persistence: default file-backed persistence included +- Logging: default console logger included +- Built-in tools in v1: `read`, `write`, `edit`, `exec`, `process` +- Hosted tools: supported and first-class +- Images: supported for user input when the selected Anthropic model supports images +- VisionClaw compatibility: optional subpath, not part of the core public API story + +## 4. Non-Goals + +The following are explicitly out of scope for public v1: + +- OpenClaw gateway +- channel runtimes +- message routing +- owner notifications +- cron +- node host control plane +- plugin loading +- plugin hooks +- `plugin-sdk` as a public compatibility promise +- multi-provider support +- auth profile rotation +- provider failover +- runtime plugin registration +- channel-specific tools such as `message`, `gateway`, `nodes` +- session-management tools such as `sessions_*` +- browser automation in the default SDK surface +- subagents +- channel-aware prompt shaping +- VisionClaw-specific canonical session ownership +- silent stub fallback behavior when credentials are missing + +Public v1 is not required to reach full feature parity with full OpenClaw embedded mode. + +## 5. Source Facts This Spec Relies On + +### 5.1 Official OpenClaw embedding boundary + +The official embeddable seam in OpenClaw is the embedded runner path centered on +`runEmbeddedPiAgent()` and the underlying `createAgentSession()` / `SessionManager` flow, not the +gateway stack. + +Within the upstream runtime, that path currently mixes together: + +- session manager lifecycle +- context-engine setup and compaction +- provider/model resolution +- auth profile resolution +- runtime plugin loading +- client-hosted tool handling through `pendingToolCalls` +- many channel and messaging concerns + +This is the right architectural seam, but the public SDK must expose only a strict subset of that +behavior. + +### 5.2 Current repository strengths + +The current repository already has useful public-SDK building blocks: + +- a session-first public API under `src/public/*` +- structured stream events +- hosted-tool definitions and result submission APIs +- transcript persistence +- host logging hooks +- a VisionClaw compatibility adapter +- a vendored agent loop and Anthropic streaming provider +- a minimal local tool implementation set + +### 5.3 Current repository gaps + +The current repository also has several product-level gaps that block a public release: + +- hosted-tool resume in the real loop path is not a full same-turn continuation yet +- the current public API still exposes plugin-related concepts +- the current runtime path is effectively Anthropic-only but the docs imply a larger provider story +- missing credentials can fall back to a stub path instead of failing fast +- public ergonomics are too host-framework oriented because callers must always supply their own + `sessionStore` and `logger` +- the package name, README title, and exported type names are currently inconsistent + +## 6. Public v1 Capability Contract + +Public v1 must provide the following guarantees. + +### 6.1 SDK lifecycle + +- The caller can bootstrap the SDK once. +- The caller can create and reuse sessions explicitly. +- The caller can shut the SDK down cleanly. + +### 6.2 Session lifecycle + +- A session has a stable host-visible identity. +- A session can stream a user turn. +- A session can stop an in-flight turn. +- A session can expose usage snapshots. +- A session can request compaction. +- A session can be resumed from persisted state after process restart. + +### 6.3 Event model + +The public event contract must preserve execution-layer semantics rather than flattening everything +into text. + +At minimum, the event model must support: + +- `assistant_delta` +- `reasoning_delta` +- `reasoning_end` +- `tool_call` +- `tool_result` +- `tool_error` +- `hosted_tool_call` +- `usage_snapshot` +- `compaction_started` +- `compaction_finished` +- `turn_complete` + +### 6.4 Hosted-tool protocol + +Hosted tools are a core public feature. + +The SDK must: + +- emit a hosted-tool event with a stable `callId` +- suspend the current turn at that boundary +- persist enough state to resume the same session after the tool result is supplied +- resume the same turn when the host supplies `submitHostedToolResult()` or `submitHostedToolError()` +- emit `turn_complete` only after the resumed turn actually completes + +This is stricter than the current synthetic resume shortcut. + +### 6.5 Built-in tools + +Public v1 includes only these built-in tools: + +- `read` +- `write` +- `edit` +- `exec` +- `process` + +The default public surface does not include: + +- `browser` +- `message` +- `gateway` +- `cron` +- `nodes` +- `sessions_*` + +`web_fetch` and `web_search` are deferred to a later release. They are not required for public v1. + +### 6.6 Anthropic-only provider scope + +Public v1 supports Anthropic only. + +That means: + +- the public options surface uses an explicit Anthropic provider configuration +- there is no public `authProfileId` +- there is no public multi-provider failover promise +- there is no public plugin-driven provider override path +- missing Anthropic credentials are a hard error + +## 7. Public API Shape + +Public v1 keeps the session-first architecture but simplifies and hardens the contract. + +### 7.1 Naming cleanup + +The public surface must standardize on these names: + +- `createOpenClawAgentSdk` +- `OpenClawAgentSdk` +- `OpenClawAgentSdkOptions` +- `OpenClawAgentSession` +- `OpenClawSessionParams` +- `OpenClawTurnInput` +- `OpenClawStreamEvent` + +The current accidental `GeneralAgentAgentSdk` style naming must be removed. + +### 7.2 SDK options + +Public v1 options should look conceptually like this: + +```ts +export interface OpenClawAgentSdkOptions { + workspaceDir: string; + dataDir?: string; + logger?: OpenClawHostLogger; + sessionStore?: OpenClawSessionStoreAdapter; + provider: { + anthropicApiKey: string; + baseUrl?: string; + }; + builtInTools?: Array<"read" | "write" | "edit" | "exec" | "process">; + hostedTools?: OpenClawHostedToolDefinition[]; + execPolicy?: { + allowed: boolean; + cwd?: string; + }; +} +``` + +Public v1 must remove these concepts from the top-level public options surface: + +- `pluginMode` +- `enabledPluginIds` +- generic `env` bags +- host-facing `profileId` +- host-facing `agentDir` + +If the internal runtime still needs internal storage directories, the SDK must derive them from +`dataDir` rather than forcing public callers to understand OpenClaw's historical directory layout. + +### 7.3 Session params + +Public v1 session creation should look conceptually like this: + +```ts +export interface OpenClawSessionParams { + sessionId: string; + sessionKey?: string; + mode?: "general" | "coding"; + systemPrompt: string; + model: string; + transcriptPath?: string; + rawEventLogPath?: string; +} +``` + +Public v1 must remove these concepts from public session params: + +- `authProfileId` +- free-form `modelRef` with hidden provider semantics + +The SDK may still map the public `model` string into internal provider-specific runtime state. + +### 7.4 Defaults + +Public v1 must ship default implementations for: + +- `createFileSessionStore(...)` +- `createConsoleLogger(...)` + +Custom adapters remain supported, but they are optional rather than mandatory. + +## 8. Target Architecture + +### 8.1 Layer split + +Public v1 has four internal layers. + +1. `src/public/*` + - stable supported API surface + +2. `src/core/public-runtime/*` + - SDK-owned runtime orchestration for public use + - session lifecycle + - persistence defaults + - tool policy + - provider bootstrap + +3. `src/upstream/openclaw/*` + - vendored upstream implementation fragments + - never directly exported as public API + +4. `src/compat/visionclaw/*` + - optional compatibility adapter + - explicitly not part of the public-core design + +### 8.2 Official-source alignment + +The public runtime must move closer to the official embedded seam rather than continuing to grow as +a custom alternative runtime. + +The intended direction is: + +- reuse official embedded-session/session-manager behavior where it materially affects persistence, + continuity, or compaction correctness +- keep using vendored upstream code under `src/upstream/openclaw/*` +- strip channel, plugin, and gateway concerns out of the public runtime adapter +- keep all upstream-specific complexity private behind the SDK surface + +Public v1 does **not** need to expose `runEmbeddedPiAgent()` directly. It does need to align its +behavior with the same underlying execution semantics wherever those semantics matter to public users. + +### 8.3 Hosted-tool continuation design + +Hosted-tool suspend/resume is the highest-priority runtime fix. + +The target behavior is: + +1. User turn starts. +2. Model decides to call a hosted tool. +3. SDK emits `tool_call`. +4. SDK emits `hosted_tool_call`. +5. Session is marked as suspended with persisted pending-call state. +6. Host executes the tool externally. +7. Host submits the result with the same `callId`. +8. SDK injects the tool result back into the same underlying session/attempt context. +9. Model continues and may emit more assistant text, more tool calls, or another hosted tool call. +10. SDK emits `turn_complete` only when that resumed execution actually ends. + +The current `createHostedToolResumeEvents()` synthetic shortcut is not sufficient for public v1 and +must be replaced in the real runtime path. + +### 8.4 Persistence model + +Public v1 persistence has two layers: + +- transcript/session state owned by the underlying agent session runtime +- lightweight SDK metadata owned by the public session store + +The default file-backed session store must persist: + +- `sessionId` +- `sessionKey` +- transcript path +- latest usage snapshot +- selected model +- last-updated timestamp +- pending hosted-tool call metadata when suspended + +The transcript file remains the source of truth for message/tool history.
