"headless":{"finding":"`letta -p \"<prompt>\"` runs one prompt non-interactively; with no prompt argument -p reads piped stdin. --output-format text|json|stream-json; bidirectional mode via --input-format stream-json. Approvals auto-answered with --yolo (permission mode unrestricted) or --permission-mode acceptEdits; explicit deny rules still apply. No working-directory flag documented (agent resolved from current directory; docs' cron examples `cd /path/to/project &&`). Exit codes not documented.","quote":"letta -p \"Look around this repo and write a README.md documenting it\" ... echo \"Explain this error\" | letta -p ... Use `--yolo` to set permission mode to `unrestricted`.","url":"https://docs.letta.com/letta-code/headless","third_party":false},
"confinement":{"finding":"Tool-level permission system only: modes unrestricted(yolo)/standard/acceptEdits/strict; allow/deny rules such as Bash(npm run lint), Bash(rm -rf:*), Read(src/**) in .letta/settings.json or via --allowedTools/--disallowedTools; --tools limits loaded tools. No OS-level sandbox (Docker/seatbelt/bubblewrap) and no network switch documented on the permissions page. README mentions a Letta Cloud 'Managed Sandbox' / `--computer cloud` remote sandbox, not a local confinement.","quote":"strict: Ask before every tool call, including reads, skills, and normally safe shell commands ... \"Bash(rm -rf:*)\", \"Bash(git push --force:*)\"","url":"https://docs.letta.com/letta-code/permissions","third_party":false},
"token_reporting":{"finding":"Yes. --output-format json returns a `usage` object with prompt_tokens and completion_tokens (plus agent_id, conversation_id); stream-json emits a usage_statistics event with the same fields. No cached, reasoning or cost fields documented.","quote":"Returns a structured JSON response with metadata.","url":"https://docs.letta.com/letta-code/headless","third_party":false},
"parallelism":{"finding":"Yes. Main agent launches subagents (built-in general-purpose, forked, recall, or custom Markdown+YAML in .letta/agents/ or ~/.letta/agents/), each in its own process; can run in background mode with completion notifications injected. Agents can call other agents as subagents. Running many separate headless sessions at once is not explicitly documented.","quote":"Call built-in subagents (general-purpose, forked, recall) in the background. Agents can call any other agent (including themselves) as subagents","url":"https://github.com/letta-ai/letta-code/blob/main/README.md","third_party":false},
"providers":{"finding":"Anthropic API, OpenAI API, Google Gemini, Groq, Mistral, Amazon Bedrock, OpenRouter, Z.ai coding plan, Letta Cloud models, plus local endpoints Ollama, LM Studio, llama.cpp (local agents only) and OpenAI-compatible endpoints.","quote":"The Letta CLI and web app support a wide variety of LLM providers and coding subscription plans.","url":"https://docs.letta.com/letta-code/models","third_party":false},
"subscription_login":{"finding":"Yes: ChatGPT Plus/Pro via device-code login ('ChatGPT/Codex Sub'); GitHub Copilot subscription (local setup); OpenRouter OAuth; Letta account via /login. No Claude Pro/Max subscription login documented (Anthropic by API key only).","quote":"For ChatGPT Plus or Pro, choose ChatGPT/Codex Sub, select Get device code, and complete the login.","url":"https://docs.letta.com/letta-code/models","third_party":false},
