 - 2026-07-10 补充：后台 Agent Runtime 的白名单工具继续扩到 `preview.start`，让 Agent 在完成写盘或静态自检后能按策略自行启动当前项目的 `127.0.0.1` 本地 HTTP 预览。该工具复用 `preview.start` 权限策略、项目写锁、共享 `PreviewRegistry`、manifest 预览状态、`.agent/logs/preview.log` 和 run trace 追加逻辑；写入 `.agent/agent.db` 的审计类型为 `agent.runtime.preview.start`。发给 LLM 的 observation 只包含 localhost URL 和端口，不包含用户项目绝对路径。
 - 2026-07-10 补充：后台 Agent Runtime 的白名单工具继续扩到 `canvas.asset_generate`，让美术类 Agent 可在 loop 中自行请求生成首版美术素材。该工具读取 AppData / Tauri 配置中的 `editorApi`，复用 `canvas.asset_generate` 权限策略、项目写锁、External Editor API 生成和下载链路、manifest 资产登记以及 `canvas.asset_generate` 本地索引记录；另写 `agent.runtime.canvas.asset_generate` 记录到 `.agent/agent.db`，标明触发的 agent 与本地素材路径。API Key 不进入 prompt observation、manifest、agent.db 或日志；策略要求确认或拒绝时不会调用外部 API。
 - 补充：规范 Agent ID 统一使用 manifest taskId，例如 `art-asset-plan` 和 `code-prototype`；历史前端曾使用的 `group-role` 别名只在 Tauri command 层兼容并映射到规范 taskId。主窗口 Agent 状态列表通过 `read_game_creator_agent_runtimes` 批量读取 `.agent/runtime/agents/<taskId>.json` 和最近任务，把每个 Agent 的 Runtime 状态、当前动作和最近 task 直接显示在状态卡片和 `/agents` 汇总里。
+- 2026-07-10 补充：单 Agent 聊天和后台 planning prompt 统一注入本 Agent 的 Runtime 连续上下文，包括最近状态、runId、当前任务、计划、观察、最近回复、最近工具动作、最近事件、最近任务和工具策略摘要；上下文只按规范 taskId 读取本 Agent runtime，进入 prompt 前过滤密钥和本机绝对路径。新后台 run 启动时继承同 Agent 上次 `recentToolCalls` 和 `lastResponse`，让下一轮任务能基于前一轮真实行动证据继续推理，同时不串入其他 Agent 的 runtime。
 - 影响范围：`apps/ai-game-creator-shell` 的 Tauri command、Agent Runtime state/event、开发窗口单 Agent 聊天、项目内 Agent 对话弹窗、`appSurface.test.ts` 和 AI 游戏创作 App 实施计划。
 - 验证方式：运行 Tauri Rust 后台 Agent 并行测试、壳前端 appSurface 测试、壳 typecheck、编码检查和 `git diff --check`。

 - 后台任务能力：开发窗口单 Agent 聊天和项目内 Agent 对话弹窗可把当前输入投递为单 Agent 后台任务，Tauri 命令 `start_game_creator_agent_runtime_task` 会立即写入该 Agent 的 `.agent/runtime/agents/<agentId>.json`、`.agent/runtime/events/<agentId>.jsonl`、`.agent/runtime/tasks/<agentId>.jsonl` 和 `.agent/conversations/agents/<agentId>.jsonl`，随后在 App 进程内启动 tokio task 执行最小 Agent loop：每轮让该 Agent 输出 `thinkingSummary / plan / actions / response`，Runtime 按白名单和项目权限策略执行工具动作，写入 `action / observation` 事件，再把 observation 放入下一轮 prompt 让 Agent 修正计划、继续行动或用空 actions + response 收束；后台任务最多执行 3 轮 loop，仍未收束时再按最后计划和全部观察生成最终回复并追加回对话。工具箱包含只读工具 `memory.read`、`conversation.read`、`asset.list`、`project.index`、`file.read`，以及受策略保护的写/运行工具 `memory.write`、`file.write`、`command.run_limited`、`blackboard.write` 和 `agent.message`；`memory.write` 可追加或覆盖本 Agent 私有记忆、项目长期/短期记忆或黑板，`file.write` 只能写项目内相对路径并记录审计，`command.run_limited` 只接受 `game.static_smoke` 并复用本地静态自检安全边界，`blackboard.write` 追加 `memory/blackboard.md`，`agent.message` 给目标 `.agent/conversations/agents/<agentId>.jsonl` 写入 tool 留言，策略要求确认或拒绝时不执行写入或运行，只把策略结果作为 observation 回给 Agent。`read_game_creator_agent_runtime` 会按 `runId` 去重返回最近任务，`read_game_creator_agent_runtimes` 批量读取所有规范 taskId 的 runtime；开发窗口、项目内 Agent 对话弹窗和主窗口 Agent 状态列表展示最近任务、当前任务、当前动作、下一步和运行阶段。不同 Agent 使用各自 runtime 锁，可以并行运行；同一 Agent 已有运行任务时，新任务会先写成 `pending / queued`，由当前后台 drain 在完成后串行继续执行。该能力仍属于 Runtime V1 的进程内任务，不是独立 OS 进程或跨重启离线常驻 worker。
 - 2026-07-10 补充：Agent Runtime state 新增 `toolPolicy`，按当前项目 `.agent/policy.json` 派生工具级 `allowedTools / autoTools / confirmTools / deniedTools` 快照；后台 planning prompt 会带入该快照，让 Agent 在规划时知道哪些工具会自动执行、需要确认或被拒绝。`blackboard.write` 继承 `memory.write` 策略，`agent.message` 继承 `conversation.write` 策略；实际执行仍以 Runtime 的白名单和项目权限 gate 为准。
 - 2026-07-10 补充：Agent Runtime state 新增 `recentToolCalls`，每次后台工具执行后记录最近 20 条结构化工具动作，包含 tool、status、reason、summary、detail 和 updatedAt；开发窗口、项目内 Agent 对话弹窗和主窗口 Agent 状态列表可直接展示“最近动作”，不再只能从 observation 字符串里猜测 action / observation 对应关系。字段只保存过滤后的摘要和观察细节，不保存原始 API Key 或任意未过滤输入。
+- 2026-07-10 补充：单 Agent 聊天和后台 planning prompt 会读取同一个 Agent 的 Runtime 连续上下文，把本 Agent 最近 status / phase / runId / 当前任务 / 下一步、最近回复、计划、观察、最近 3 条工具动作、最近事件、最近 3 条任务记录和工具策略摘要带入下一轮推理；上下文按规范 taskId 隔离，不读取其他 Agent 的 runtime 文件，并在进入 prompt 前过滤密钥和本机绝对路径。新后台 run 启动时会继承本 Agent 上次 `recentToolCalls` 和 `lastResponse`，让多轮任务不丢失结构化行动证据。
 - 2026-07-10 补充：后台任务工具箱已加入 `preview.start`。Agent 可在 loop 中自行请求启动当前项目的本地 HTTP 预览；Runtime 会复用 `preview.start` 策略、项目写锁、共享 `PreviewRegistry`、manifest 预览状态、`.agent/logs/preview.log` 和 run trace 追加逻辑，并把 `agent.runtime.preview.start` 写入 `.agent/agent.db`。该 observation 只向 LLM 返回 localhost URL 与端口，不返回用户项目绝对路径。
 - 2026-07-10 补充：后台任务工具箱已加入 `canvas.asset_generate`。Agent 可在 loop 中自行给出素材 prompt，通过 AppData / Tauri 配置里的 `editorApi` 调用 External Editor API 生成首版美术素材、下载到 `assets/canvas-generated/` 并登记 manifest；Runtime 复用 `canvas.asset_generate` 策略和项目写锁，并写入 `agent.runtime.canvas.asset_generate` 审计记录。API Key 不进入 observation、manifest、agent.db 或日志；策略要求确认或拒绝时不会调用外部 API。
 - 2026-07-10 补充：后台任务工具箱已加入 `task.list`。Agent 可在 loop 中读取 manifest 任务图、每个 seed task 的状态 / 依赖 / 产物交接，以及按依赖计算的 `readyTaskIds`；Runtime 复用 `task.list` 项目权限策略，策略要求确认或拒绝时只返回策略 observation，不向 LLM 暴露任务图细节。
