The provider now implements `read`, `ls`, `grep`, and `glob` directly against the in-memory VFS, path resolution is confined to the virtual workspace root, and legacy `VfsSandbox` / `createVfsSandboxFactory*` aliases are removed. ## @langchain/quickjs@0.5.0 ### Minor Changes - [#590](https://github.com/langchain-ai/deepagentsjs/pull/590) [`7ee3feb`](https://github.com/langchain-ai/deepagentsjs/commit/7ee3feb674c361305b2a031db9132253e3d0543b) Thanks [@colifran](https://github.com/colifran)! - chore(quickjs): remove skills backend and associated plumbing - [#592](https://github.com/langchain-ai/deepagentsjs/pull/592) [`72cfb0c`](https://github.com/langchain-ai/deepagentsjs/commit/72cfb0c0384b30059b5e8028139a2e167c1be882) Thanks [@colifran](https://github.com/colifran)! - feat(quickjs): implement default subagent primitive in code interpreter for programmatic subagent calling ### Patch Changes - [#594](https://github.com/langchain-ai/deepagentsjs/pull/594) [`61db938`](https://github.com/langchain-ai/deepagentsjs/commit/61db9381494f61b4548cd80b715e5af72fdde381) Thanks [@colifran](https://github.com/colifran)! - chore(quickjs): remove configurable concurrency and add subagents option with true default - [#546](https://github.com/langchain-ai/deepagentsjs/pull/546) [`b7a5f26`](https://github.com/langchain-ai/deepagentsjs/commit/b7a5f26fd9cba992b11e1a4cf18607d64533503b) Thanks [@open-swe](https://github.com/apps/open-swe)! - fix(quickjs): scope `CodeInterpreterMiddleware` REPL prompt sandbox bullet to the runtime ## deepagents-acp@0.1.14 ### Patch Changes - Updated dependencies [[`18557db`](https://github.com/langchain-ai/deepagentsjs/commit/18557db7bbdf92052ed5f994512fb70e11989e69), [`773cac5`](https://github.com/langchain-ai/deepagentsjs/commit/773cac5dc7efc7843dd882642d91f7d64d6fde81), [`1ca6dc9`](https://github.com/langchain-ai/deepagentsjs/commit/1ca6dc92fd40a6d845d24b95ba14b8f2643db394), [`03df237`](https://github.com/langchain-ai/deepagentsjs/commit/03df237385fbdfefd862076c5588eb39cb6e43c3), [`84f3c0c`](https://github.com/langchain-ai/deepagentsjs/commit/84f3c0c2f1cad271191bcc138b84ba5b9c9205c9), [`72cfb0c`](https://github.com/langchain-ai/deepagentsjs/commit/72cfb0c0384b30059b5e8028139a2e167c1be882), [`04cc3fc`](https://github.com/langchain-ai/deepagentsjs/commit/04cc3fc26001ee566ed94de44c2dda2cf6adecc4), [`18fbb48`](https://github.com/langchain-ai/deepagentsjs/commit/18fbb4839050e98ae3cfd36ec69b11f0725ad6d6), [`e3d4b53`](https://github.com/langchain-ai/deepagentsjs/commit/e3d4b5367b1825df56c919b483ec4a3e117d631f)]: - deepagents@1.10.4 ## deepagents@1.10.4 ### Patch Changes - [#551](https://github.com/langchain-ai/deepagentsjs/pull/551) [`18557db`](https://github.com/langchain-ai/deepagentsjs/commit/18557db7bbdf92052ed5f994512fb70e11989e69) Thanks [@antonnak](https://github.com/antonnak)! - fix(deepagents): gate cache_control writes on per-call request.model `createCacheBreakpointMiddleware` and `createMemoryMiddleware` were gating the Anthropic-specific `cache_control` write at agent-creation time only. When `modelFallbackMiddleware` swapped `request.model` to a non-Anthropic provider mid-flight (e.g. on Anthropic 5xx), the marker leaked through and the fallback provider rejected the request with `400 Unknown parameter: 'cache_control'`. Both middlewares now also check `isAnthropicModel(request.model)` inside `wrapModelCall`. Fixes [#550](https://github.com/langchain-ai/deepagentsjs/issues/550). - [#591](https://github.com/langchain-ai/deepagentsjs/pull/591) [`773cac5`](https://github.com/langchain-ai/deepagentsjs/commit/773cac5dc7efc7843dd882642d91f7d64d6fde81) Thanks [@colifran](https://github.com/colifran)! - chore(deepagents): expose createSubAgent - [#541](https://github.com/langchain-ai/deepagentsjs/pull/541) [`1ca6dc9`](https://github.com/langchain-ai/deepagentsjs/commit/1ca6dc92fd40a6d845d24b95ba14b8f2643db394) Thanks [@ixchio](https://github.com/ixchio)! - fix getMimeType to return application/octet-stream for unknown file extensions instead of text/plain - [#572](https://github.com/langchain-ai/deepagentsjs/pull/572) [`03df237`](https://github.com/langchain-ai/deepagentsjs/commit/03df237385fbdfefd862076c5588eb39cb6e43c3) Thanks [@hntrl](https://github.com/hntrl)! - fix: scope CompositeBackend grep/glob route fanout by search path CompositeBackend now limits fallback route fanout to routes mounted under the requested search path, instead of querying all routed backends unconditionally. This avoids unrelated routed backend calls (and side-effect errors) for scoped searches like `path="/workspace"`, while preserving full fanout behavior at root (`path="/"`). - [#574](https://github.com/langchain-ai/deepagentsjs/pull/574) [`84f3c0c`](https://github.com/langchain-ai/deepagentsjs/commit/84f3c0c2f1cad271191bcc138b84ba5b9c9205c9) Thanks [@hntrl](https://github.com/hntrl)! - fix(deepagents): add explicit browser and node entrypoints - add `deepagents/browser` and `deepagents/node` subpath exports - route browser bundlers to the browser-safe bundle via the root `browser` export condition - avoid named Node builtin imports in backend utils that can break browser builds - document browser guidance to import from `deepagents/browser` - [#592](https://github.com/langchain-ai/deepagentsjs/pull/592) [`72cfb0c`](https://github.com/langchain-ai/deepagentsjs/commit/72cfb0c0384b30059b5e8028139a2e167c1be882) Thanks [@colifran](https://github.com/colifran)! - feat(quickjs): implement default subagent primitive in code interpreter for programmatic subagent calling - [#566](https://github.com/langchain-ai/deepagentsjs/pull/566) [`04cc3fc`](https://github.com/langchain-ai/deepagentsjs/commit/04cc3fc26001ee566ed94de44c2dda2cf6adecc4) Thanks [@hntrl](https://github.com/hntrl)! - fix(deepagents): propagate subagent `lc_agent_name` during task delegation - Ensure `task` tool subagent invocations override `metadata.lc_agent_name` with the selected `subagent_type`. - Add regression coverage for both compiled subagents (`runnable`) and standard subagent specs to verify tool-time metadata reflects the active subagent. - Update the `langsmith` peer dependency range in `deepagents` to `^0.7.1`. - [#595](https://github.com/langchain-ai/deepagentsjs/pull/595) [`18fbb48`](https://github.com/langchain-ai/deepagentsjs/commit/18fbb4839050e98ae3cfd36ec69b11f0725ad6d6) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(deepagents): count tokens once per model call in summarization middleware `createSummarizationMiddleware` counted tokens twice on every model call—once inside `truncateArgs` and again for the should-summarize check—even when nothing was truncated or summarized. Count once and pass the total into `truncateArgs`; recount only when truncation actually modifies messages. - [#242](https://github.com/langchain-ai/deepagentsjs/pull/242) [`e3d4b53`](https://github.com/langchain-ai/deepagentsjs/commit/e3d4b5367b1825df56c919b483ec4a3e117d631f) Thanks [@alvedder](https://github.com/alvedder)! - feat(deepagents): support direct skill paths as sources in createSkillsMiddleware ## @deepagents/evals@0.0.13 ### Patch Changes - Updated dependencies [[`18557db`](https://github.com/langchain-ai/deepagentsjs/commit/18557db7bbdf92052ed5f994512fb70e11989e69), [`773cac5`](https://github.com/langchain-ai/deepagentsjs/commit/773cac5dc7efc7843dd882642d91f7d64d6fde81), [`1ca6dc9`](https://github.com/langchain-ai/deepagentsjs/commit/1ca6dc92fd40a6d845d24b95ba14b8f2643db394), [`03df237`](https://github.com/langchain-ai/deepagentsjs/commit/03df237385fbdfefd862076c5588eb39cb6e43c3), [`84f3c0c`](https://github.com/langchain-ai/deepagentsjs/commit/84f3c0c2f1cad271191bcc138b84ba5b9c9205c9), [`72cfb0c`](https://github.com/langchain-ai/deepagentsjs/commit/72cfb0c0384b30059b5e8028139a2e167c1be882), [`04cc3fc`](https://github.com/langchain-ai/deepagentsjs/commit/04cc3fc26001ee566ed94de44c2dda2cf6adecc4), [`18fbb48`](https://github.com/langchain-ai/deepagentsjs/commit/18fbb4839050e98ae3cfd36ec69b11f0725ad6d6), [`e3d4b53`](https://github.com/langchain-ai/deepagentsjs/commit/e3d4b5367b1825df56c919b483ec4a3e117d631f)]: - deepagents@1.10.4 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>
