…ly features Harness profiles ARE available in the TypeScript SDK via registerHarnessProfile. Previous commit incorrectly said they were Python-only. Changes: - Add :::js sections with TypeScript code examples (registerHarnessProfile, HarnessProfileOptions, parseHarnessProfileConfig, serializeProfile) - Add :::js ResponseField entries with camelCase TS field names - Wrap Python-specific content (HarnessProfile class, import forms, provider profiles, entry-point plugin system) in :::python blocks - Note in :::js that provider profiles and plugin registration are Python-only - Update shared prose (Notes, merge semantics table) to reference both Python/TS APIs
- Split Note about system_prompt=/systemPrompt into separate :::python/:::js blocks - Split Note about create_deep_agent/createDeepAgent into separate :::python/:::js blocks - Split merge semantics table into separate :::python/:::js tables with language-specific field names - Split Related customization link into separate :::python/:::js entries

## Overview Adds the final `deepagents` v0.7.0 changelog entry, replacing the pre-release `v0.7.0a6` block. The v0.7.0 release focuses on making the harness more configurable and leaner by default. Content is sourced from the [`0.7.0b1`](https://github.com/langchain-ai/deepagents/releases/tag/deepagents%3D%3D0.7.0b1) and [`0.7.0b2`](https://github.com/langchain-ai/deepagents/releases/tag/deepagents%3D%3D0.7.0b2) release notes and grouped into Features, Optimizations, and Breaking changes. Note: the `SystemPromptConfig` item from the old a6 entry was dropped because that feature was reverted ([deepagents#4969](langchain-ai/deepagents#4969)) before the GA release. ## Type of change **Type:** Update existing documentation ## Related issues/PRs - Feature PRs: langchain-ai/deepagents#4251, #4109, #4325, #4859, #4929, #4541, #5009 ## Checklist - [x] I have read the contributing guidelines, including the language policy - [x] I have tested my changes locally (Vale: 0 errors, 0 warnings) - [x] All code examples have been tested and work correctly - [x] I have used **root relative** paths for internal links - [ ] I have updated navigation in `src/docs.json` if needed (not needed)

Summary

profiles.mdxpage had no:::python/:::jsconditional guards. The build pipeline generates bothoss/python/deepagents/profilesandoss/javascript/deepagents/profilesfrom the same source file, so all Python code blocks were being rendered verbatim on the JS page.Links
Verification
Docs-only conditional guard change — no scripts to run. Confirmed
:::js/:::pythonpattern matches existing usage incustomization.mdx(which already correctly hides the profiles section in its JS build).Reviewers
