* Add Letta Cloud-only warning to SDK v1.0 migration guide
Added prominent warning at the top of the SDK v1.0 migration guide to clarify that:
- SDK v1.0 is only supported on Letta Cloud
- Self-hosted Letta v0.13.x does NOT support SDK v1.0
- Users should continue using SDK v0.x with self-hosted until future releases
This prevents confusion for self-hosted users trying to upgrade to SDK v1.0.

* Add archival memory import/export utilities
Added two utility scripts for managing agent archival memories:
- export_agent_memories.py: Export all passages from an agent to JSON
- Paginates through all results
- Removes embedding/embedding_config for portability
- Usage: python export_agent_memories.py <agent_id> [--output <file>]
- import_agent_memories.py: Import passages into an agent from JSON
- Batch imports with progress tracking
- Handles optional fields (tags, created_at)
- Includes dry-run mode for preview
- Usage: python import_agent_memories.py <agent_id> <input_file>
Use cases:
- Backup/restore agent memories
- Transfer memories between agents
- Seed new agents with existing knowledge bases

* docs: migrate documentation to cloud-first approach
Update all documentation to use Letta Cloud as the default deployment path:
- Remove base_url parameter from cloud examples (uses api.letta.com by default)
- Add token authentication to all SDK examples
- Change localhost URLs to https://api.letta.com in all examples
- Remove embedding parameter from cloud examples (managed automatically)
- Add comprehensive embedding configuration section to self-hosting guide
- Add warnings about required embedding configuration for self-hosted deployments
- Update curl examples to include Authorization headers
- Link to https://app.letta.com/api-keys for token retrieval
Files updated:
- Agent guides (11 files)
- Model configuration pages (5 files)
- Evals documentation (6 files)
- ADE guides (2 files)
- Self-hosting guide
- Voice integration guide
- README
- Quickstart
* docs: fix embedding parameter issues in cloud examples
- Remove leftover embedding parameter from TypeScript example in agents/overview.mdx
- Make self-hosting comment more explicit in README by showing actual embedding parameter syntax
* docs: fix model configuration pages to be self-hosting focused
Model configuration pages (OpenAI, Anthropic, Azure, xAI, Ollama) are about
configuring providers on self-hosted servers, not Letta Cloud. Updated all
SDK examples to:
- Use base_url="http://localhost:8283" instead of cloud token auth
- Include embedding parameter with clear comment
- Use consistent "An embedding model is required for self-hosted" wording
- Add Note directing cloud users to quickstart guide
This clarifies that provider configuration is a self-hosting concern, while
Letta Cloud manages providers automatically.
* fix: remove duplicate Authorization headers in human-in-the-loop docs
* chore: remove utility scripts that shouldn't be in repo

Removes all references to pip installation (pip install letta) and the
letta server command from documentation, as Docker is now the only
supported installation method for self-hosting Letta.
Changes:
- Removed pip installation accordion from selfhosting/overview.mdx
- Updated FAQ to indicate Docker is required
- Removed CLI/pip sections from all model provider docs (13 files):
* OpenAI, Anthropic, Groq, Google AI, DeepSeek, xAI, Together.AI
* AWS Bedrock, Azure OpenAI, Google Vertex AI
* Ollama, LM Studio, vLLM, OpenAI Proxy
- Removed "letta server" tabs from agent tool docs (web_search,
fetch_webpage, run_code)
- Updated evals getting-started.mdx to use Docker in error messages
All references now point to Docker installation with links to the
self-hosting guide. SDK installation (pip install letta-client) remains
intact for developers using the Letta API.

Moves Human-in-the-Loop documentation from the Experimental section
to the Tool Use section, as it is a stable feature for tool approval
workflows.
Changes:
- Moved Human-in-the-Loop page to Tool Use section after Tool Variables
- Removed from Experimental section in docs navigation
- Removed experimental warning from human_in_the_loop.mdx
Human-in-the-Loop is now positioned alongside other tool-related
features, making it easier for users to discover when implementing
tool approval workflows.
