missing value for --model

Error message

missing value for --model

What it means

Thrown by parse_dump_all_flags when `--model`/`-m` is the last token of `openhuman agent dump-all`, so no value token follows to read as the model name.

Solutions

1. Drop the trailing `--model` (model is optional) or provide a model id, e.g. `--model claude-sonnet-4`.
2. Quote and default model variables in wrappers so the flag never dangles.

Example fix

# before
openhuman agent dump-all --out ./p --model

# after
openhuman agent dump-all --out ./p --model gpt-5

# append --model only when provided
CMD=(openhuman agent dump-all --out "$OUT_DIR")
[ -n "${MODEL:-}" ] && CMD+=(--model "$MODEL")
"${CMD[@]}"

match run_agent_command(&args) {
    Err(e) if e.to_string().contains("missing value for --model") => {
        eprintln!("--model needs a model id after it (or omit the flag)");
    }
    other => other?,
}

When it happens

Trigger: `openhuman agent dump-all --out d --model` as the end of the command line.

Common situations: Appending an optional model override from an empty shell variable, or pausing mid-command and submitting early.
