OpenCode

Run OpenCode agents under authsome. Same proxy and library patterns as the rest of the CLI.

OpenCode is an open-source AI coding agent. It runs as a CLI, calls LLMs over HTTPS, and shells out to local tools. Authsome plugs in via the same two patterns we use everywhere: wrap the agent under authsome run --, or call the library from inside.

The agent drives login. When OpenCode hits a missing credential it can run authsome login <provider> itself, opening a browser on your machine for OAuth consent. Don’t paste keys into prompts; pre-seed a credential only when an agent can’t reach a browser (CI, SSH).

Recommended pattern: wrap the agent

authsome login github
authsome login openai
authsome run -- opencode

OpenCode sees placeholder env vars (OPENAI_API_KEY=authsome-proxy-managed) but never the real key. Outbound HTTPS to matched provider hosts is authenticated by the proxy.

Embedding the library

If you’re orchestrating OpenCode from a larger Python program and need explicit per-call control, drop below the proxy:

authsome run -- python my_agent.py
# or: eval "$(authsome export <provider> --format env)"

See Python library.

Multi-account

authsome login github --connection personal
authsome login github --connection work
authsome login github --connection work --force
authsome run -- opencode

The proxy uses each provider’s default connection. To switch which connection the proxy uses, set it as default with --force. See Multiple connections per provider.

Troubleshooting

Symptom	Fix
OPENAI_API_KEY rejected as invalid	OpenCode is running outside authsome run. Wrap it.
TLS errors against api.openai.com	Trust the mitmproxy CA. See Proxy networking.
