### Python SDK - Agents
|
||||
|
||||
```python
|
||||
import litellm
|
||||
from litellm import Harness, sandbox
|
||||
|
||||
result = litellm.agent(
|
||||
Harness.CLAUDE_CODE, # or Harness.CODEX, Harness.OPENCODE, Harness.DEEPAGENTS
|
||||
"Find why tests/test_router.py is flaky and fix it.",
|
||||
sandbox=sandbox.local("./repo"),
|
||||
model="litellm_proxy/claude-sonnet-4-5", # a model group on your AI Gateway
|
||||
)
|
||||
|
||||
print(result.text, result.cost, [f.path for f in result.files])
|
||||
```
|
||||
|
||||
Set `LITELLM_PROXY_API_BASE` and `LITELLM_PROXY_API_KEY` and every model call the agent makes goes through your AI Gateway, tagged `harness,claude_code`. Drop the `litellm_proxy/` prefix to call a provider directly. Install `starlette uvicorn` plus the agent's CLI (`claude`, `codex` or `opencode`), or `deepagents langchain-litellm` for Deep Agents.

"""
|

Base agent-harness transformation configuration.
|
||||
|
||||
A harness is a complete agent runtime (Claude Code, Codex, OpenCode, Deep Agents).
|
||||
Like the LLM provider configs in `litellm/llms/base_llm/chat/transformation.py`, a
|
||||
harness config only translates: LiteLLM's session parameters in, the runtime's native
|
||||
command / config / event stream out. It never does I/O. A handler in
|
||||
`litellm/harness/handlers/` owns the sandbox, the process and the per-session model
|
||||
endpoint, and calls these transforms.
|
||||
|
||||
Adding a CLI harness is one subclass of `BaseCLIHarnessConfig` in
|
||||
`litellm/llms/<harness>/harness/transformation.py`, plus one line in
|
||||
`ProviderConfigManager.get_provider_harness_config`.

OpenCode harness config: `opencode run --format json`, once per turn.
|

|

Every model call goes to one custom provider (`litellm`, `@ai-sdk/openai-compatible`,
|
||||
bundled in the binary) whose baseURL is the per-session endpoint. The config travels in
|
||||
OPENCODE_CONFIG_CONTENT, which opencode applies after global and project config, so a
|
||||
repo's own opencode.json cannot redirect model calls. The token is never in argv or env:
|
||||
the config references it with `{file:<private_dir>/token}`. XDG dirs point at a persisted
|
||||
LiteLLM-owned root so the user's opencode config and auth are never read, and the session
|
||||
DB outlives a session for resume. Verified against opencode 1.14.41.
