Installed CLIProxyAPI ${VERSION} under ${DEST}

Next steps:
  1. Edit ${DEST}/config.yaml — set the 'api-keys:' list to a secret of your
     choosing (the agent runners read CLIPROXYAPI_KEY which must match).
  2. OAuth-login each upstream you intend to use, e.g.:
       cd ${DEST}
       ./cli-proxy-api --config config.yaml login claude
       ./cli-proxy-api --config config.yaml login codex
     The resulting token JSONs land in ~/.cli-proxy-api/ by default.
  3. Start the proxy in the background:
       cd ${DEST}
       nohup ./cli-proxy-api --config config.yaml > proxy.log 2>&1 &
  4. (Optional) Start the max_tokens-clamp passthrough used by aibuildai:
       cd ${HERE%/cliproxyapi}/..   # repo root
       .venv/bin/python -m agents.cliproxyapi.clamp_proxy &
  5. export CLIPROXYAPI_KEY=<the api-key you set in step 1>
