Function resolve_args_payload

src/tool_command/args.rs:555–573

Resolve a `--args` value to its JSON text. `--args` is a *whole-payload argument (the value IS the object), so it follows the same convention as `memory curate --llm-ops`: `-` reads stdin and any non-inline value is a file path — a plain path "just works" without the `@` sigil that per-key values need. Inline JSON (starting `{`/`[`) is returned verbatim; `@file` and `@-` stay valid as back-compat

(
    raw: &str,
    read_stdin: &mut impl FnMut() -> Result<String>,
)

/// values need. Inline JSON (starting `{`/`[`) is returned verbatim; `@file`
/// and `@-` stay valid as back-compat aliases so existing scripts keep working.
