+1. Call the tool after the current game files are ready to run. The attempt number is client evidence metadata; choose whether another run is useful from the returned facts.
 2. Inspect both desktop and mobile results, including page readiness, visible text, screenshots, console errors, exceptions, failed requests, Canvas probes, blocked actions, and interaction evidence.
 3. Compare screenshots with the user's request. Check that the active game fills its intended area, HUD elements do not cover gameplay, controls are visible, and requested platform art appears in the core experience.
-4. If evidence exposes a defect, edit the actual game files and call the tool again. Keep the loop bounded to three attempts per user request unless the user explicitly asks to continue.
+4. If evidence exposes a defect, edit the actual game files and call the tool again when that is useful. The client enforces its own execution and resource bounds; do not invent a fixed repair loop in the response.
 5. Treat browser infrastructure failure, an unloaded page, an unhandled exception, or missing evidence as a failed validation. Do not claim success from a partial result.

+1. Write executable source to `index.html`, `style.css`, and `game.js` in the current cwd. Use only relative paths returned by approved tools for media.
 2. Before using or deriving an existing asset, call `agc_list_registered_assets` and select its `localAssetId`; never infer a source from a filename or submit a local path, platform ID, object key, operation ID, or idempotency key as a generation argument.
 3. When the user explicitly asks to create or derive video, character animation, sound effect, or background music, call `agc_create_or_derive_resource`. Use `create` only for video/audio without a source and `derive` with a registered `sourceLocalAssetId`; character animation is always derived from an image.
 4. When the user explicitly asks to remove an image background, call `agc_remove_background` with a registered image `sourceLocalAssetId` and an output name. The client requires the signed-in account, owns canvas/folder context and task identity, and returns only bounded queue state.

+## 16. DirectProject 原生 Codex 工具解锁与薄 Runtime（2026-08-24）
+
+本节 supersede 早期“DirectProject 关闭 shell / unified exec / 任意原生工具、预注入源码快照”的实现描述。它只适用于 `CodexAppServerWorkspaceMode::DirectProject`；ToolHost 与 DirectHome 继续使用被动、只读、无 MCP 的旧合同。
+
+- DirectProject 的系统提示词只保留身份、真实 `game/` cwd、可写边界、审核 Skill 索引和副作用归属，总上限收紧为 16 KiB；不再把项目提示词、AGENTS/README/CONTEXT 或 `index.html`、`style.css`、`game.js` 快照批量塞入上下文。Codex 按需读取真实文件，避免重复上下文和过时快照。
+- DirectProject 恢复 Codex 原生文件/搜索/命令、图片查看、Skill 能力，并保留客户端审核的 `agc_tools` 本地 stdio MCP。`taonier_prepare_game_art`、资源登记、去背景、浏览器试玩和受控搜索仍走 `agc_tools`，由客户端负责权限、锁、账本、幂等、下载校验、回滚/对账和投影。
+- `approvalPolicy=never` 与 `workspaceWrite(writableRoots=[真实 game/])` 让原生工具循环不再等待 AGC 泛化审批；原生命令网络保持关闭，联网资料继续走受控 `agc_web_search`。Codex 子 Agent、插件、Apps、图片生成、Goals、Workspace Dependencies、Tool Suggestion 仍显式关闭，因为这些能力尚未接入 AGC 的 durable lock、ledger、取消与 reconciliation。原生浏览器/电脑控制继续不作为未审计副作用入口；真实试玩以 `agc_browser_playtest` 为准。
+- app-server 进程继续使用隔离 `CODEX_HOME`，只注入 `agc_tools`；不会继承用户配置的任意外部 MCP，且显式关闭 hooks。配置了 AGC LLM Key 或可解析的 `OPENAI_API_KEY` 登录态时，AGC 本地 provider proxy 持有真实凭据；前者仍走已配置上游，后者只走 OpenAI 官方 API，Codex 只拿连接级随机代理令牌。无法安全代理的 OAuth `auth.json` 继续关闭 native shell/unified exec。原生 shell 使用 Codex `shell_environment_policy` 的 core 继承与 glob 形式 secret/proxy/bridge 环境排除，provider API key、loopback bridge URL、受控搜索开关不能被 shell 子进程继承。`.agent/`、项目根和 `../assets/` 不可写；sandbox 没有 deny-read，提示词/Skill 约束与真实 smoke 共同验证客户端私有状态不被读取。
+- 旧 `platform-agent-harness`、ToolHost 的 Runtime action、AGC durable delegation 与恢复链路不删除、不改作 Codex 的第二执行权威。多 Agent 仍必须使用现有 Runtime delegation；DirectProject 的原生循环只负责其自身工作区内的即时推理和工具执行。
