Custom tools for the DeepSeek Harness: users author their own JavaScript tools in the settings UI with a Monaco (VS Code) editor and TypeScript intellisense, and the model grows and prunes the same toolset itself through custom_tool_create / custom_tool_remove / custom_tools_list. Every tool is durable, hot-registered, and written into the model prompt on the next step.
功能特性
- Untrusted code runs in-process: every call executes in a fresh worker thread inside a node:vm realm with an explicit allowlist and hard budgets, instead of eval in the agent process.
- Durable store: tools live in the custom-tools settings namespace (schema defaults, composition base, user document — the ordinary settings layering). Edits apply live; restart restores them.
- Model self-service: custom_tool_create (upsert by name), custom_tools_list, and custom_tool_remove share the UI's validation gate and the ownership rules below.
- The root is the session workspace directory (the initiating agent's cwd), resolved at call time.
- Relative paths resolve from the root; absolute paths must stay inside it; any path that escapes the root is rejected with an explicit error.
- Outside a session (no initiator context) a workspace tool fails with no workspace root rather than running without a boundary.
