## 背景与问题 AGC（AI 游戏创作智能体 App）Direct Codex 模式在携带图片工具结果等大上下文调用 LLM 时，`/api/llm/responses` 与 `/api/llm/chat/completions` 会命中 Axum 默认 **2 MiB** 请求体上限，直接被 413 拒绝，大上下文任务无法执行；同时 Codex app-server 的 failed turn 未把上游 413 映射为稳定错误分类，前端只能显示笼统的“其他错误”，无法引导用户处理。 ## 改动内容 **1. api-server（server-rs）** - 新增常量 `LLM_REQUEST_MAX_BODY_BYTES = 32 MiB`，作为两个 LLM 代理路由的正式请求体上限； - 两个路由显式配置 `DefaultBodyLimit::max(32 MiB)`，避免 Axum 默认 2 MiB 提前拒绝；handler 内保留超限检查，超过 32 MiB 仍返回 `413 PAYLOAD_TOO_LARGE`； - 补充回归测试：>2 MiB 大上下文请求不再命中默认限制；超过 32 MiB 仍返回 413。 **2. AGC 壳（apps/ai-game-creator-shell）** - `codex_app_server` 错误映射：上游/连接层 HTTP 413、`PAYLOAD_TOO_LARGE`、`provider request too large` 等统一映射为稳定分类 `codex-app-server-error:request-too-large`，不再落入 `other` 或误判为权限/安全策略错误； - 前端新增用户可见文案“模型请求体过大，请减少参考图或上下文后重试”，并补充单测断言。 **3. 文档** - 【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md 补充“2026-09-06 AGC LLM 代理请求体合同”：明确 32 MiB 上限、必须显式配置 `DefaultBodyLimit`、413 映射规则与用户文案。 ## 验证 - `cargo test -p api-server llm_routes_accept_large_context_bodies_beyond_axum_default` 通过 - `cargo test -p api-server llm_responses_rejects_bodies_above_explicit_limit` 通过 - `cargo test ... ai-game-creator-shell ... codex_app_server_failed_turn_maps_request_too_large_details` 通过 - `npm run test -- apps/ai-game-creator-shell/tests/agentRuntimeModel.test.ts`（27 通过） 全量 workspace 测试与 CI 门禁待推送后由 CI 覆盖。 Reviewed-on: #295 Reviewed-by: 段舒康 <kdletters@qq.com> Co-authored-by: 董羽秦 <suzmii@qq.com> Co-committed-by: 董羽秦 <suzmii@qq.com>
