Error message

{output.strip() or "CodeBuddy did not return an account model catalog."}

What it means

The CLI subprocess ran but its output contained no `- model-name` entries after the 'supported models for your account:' marker, so the regex extracted nothing and the provider raises RuntimeError with the CLI's combined stdout/stderr (or a fallback message). The CLI output usually reveals the real cause: not signed in, auth expired, or an error message.

Solutions

1. Run `codebuddy --print . --model ...` manually and read the captured output (it's embedded in the exception message) to see the actual CLI error.
2. Sign in: run the CodeBuddy login flow, then retry the sync.
3. If output format changed after a CLI update, pin/upgrade to a CLI version whose catalog format matches the parser.

Example fix

# before
# not signed in
await fetch_codebuddy_models()  # RuntimeError with CLI 'please sign in' output

# after
# terminal
$ codebuddy login
await fetch_codebuddy_models()

import shutil
if not (shutil.which("codebuddy") or shutil.which("cbc")):
    raise RuntimeError("CodeBuddy CLI is required to sync account models.")

try:
    models = await fetch_codebuddy_models()
except RuntimeError as e:
    logger.error("CLI output: %s", e)  # message contains the CLI stdout/stderr
    if "sign" in str(e).lower():
        # re-authenticate and retry once
        models = await fetch_codebuddy_models()
    else:
        raise

When it happens

Trigger: Running fetch_codebuddy_models() while the CodeBuddy account isn't authenticated (CLI prints a login prompt instead of a catalog); CLI version changed its output format so the marker/regex no longer match; CLI emitted an error to stderr.

Common situations: Fresh CLI install without `codebuddy login`; long-running servers whose stored session expired; CLI output-format changes after an update breaking the parser.
