For multi-step tool work this is token-heavy and serial. The model cannot compose tools — loop over a result set, branch on an intermediate value, fan out, post-process — without a full model round-trip per call, and each round-trip drags the entire intermediate result back into context whether the model needs it or not.

Cloudflare's [PTC mode](https://blog.cloudflare.com/ptc/) proposes an alternative grounded in a simple observation: LLMs are better at writing code than at emitting tool calls, because they have seen millions of lines of real code and comparatively few contrived tool-calling traces. Instead of one tool call per step, the model writes a TypeScript program against a generated API over the tools, the program executes in a sandboxed runtime, and the model curates what comes back — only what it prints or returns — instead of every intermediate result.

Tool presentation belongs to the registry that owns tool visibility: implementing a second presentation as an after-the-fact waterfall transform would make correctness depend on listener order and fight [reconstructable requests](../architecture/2026-07-05-reconstructable-requests.md). The execution substrate is also part of the foundation rather than a placeholder: Node `worker_threads` provides a separate isolate, an empty environment, heap caps, and termination of a hot synchronous loop, while fitting the harness's existing trust model (§Trust posture).

对于多步工具操作，这种方式 token 开销大且串行。模型无法组合工具——遍历结果集、根据中间值分支、扇出、后处理——每次调用都需要一次完整的模型往返，而每次往返都会把完整的中间结果拖回上下文，不管模型是否需要。 对于多步工具操作，这种方式 token 开销大且串行。模型无法组合工具——遍历结果集、根据中间值分支、扇出、后处理——每次调用都需要一次完整的模型往返，而每次往返都会把完整的中间结果拖回上下文，不管模型是否需要。
Cloudflare 的 [PTC mode](https://blog.cloudflare.com/ptc/) 提出了一种替代方案，基于一个简单的观察：LLM（大语言模型）编写代码的能力优于发出工具调用，因为它们见过数百万行真实代码，而人为构造的工具调用 trace 相对很少。模型不再每步发出一次工具调用，而是针对工具生成的 API 编写一段 TypeScript 程序，程序在沙箱运行时中执行，模型只筛选返回的内容——仅限它 print 或 return 的部分——而非所有中间结果。 Cloudflare 的 [Code Mode](https://blog.cloudflare.com/code-mode/) 提出了一种替代方案，基于一个简单的观察：LLM（大语言模型）编写代码的能力优于发出工具调用，因为它们见过数百万行真实代码，而人为构造的工具调用 trace 相对很少。模型不再每步发出一次工具调用，而是针对工具生成的 API 编写一段 TypeScript 程序，程序在沙箱运行时中执行，模型只筛选返回的内容——仅限它 print 或 return 的部分——而非所有中间结果。
工具呈现属于掌管工具可见性的注册表：如果把第二种呈现方式实现为事后的 waterfall（瀑布式事件）变换，正确性将依赖监听器顺序，并与[可重建请求](../architecture/2026-07-05-reconstructable-requests.zh.md)冲突。执行基底同样属于基础设施而非占位实现：Node `worker_threads` 提供独立 isolate、空环境、堆上限以及对热同步循环的终止能力，同时契合 harness 既有的信任模型（§信任姿态）。 工具呈现属于掌管工具可见性的注册表：如果把第二种呈现方式实现为事后的 waterfall（瀑布式事件）变换，正确性将依赖监听器顺序，并与[可重建请求](../architecture/2026-07-05-reconstructable-requests.zh.md)冲突。执行基底同样属于基础设施而非占位实现：Node `worker_threads` 提供独立 isolate、空环境、堆上限以及对热同步循环的终止能力，同时契合 harness 既有的信任模型（§信任姿态）。
