Function TestRunRawSurfacesTruncatedToolArgs

internal/tools/bash_test.go:287–303

TestRunRawSurfacesTruncatedToolArgs: the _parse_error sentinel (set by llm.resolve when the server truncates an oversized tool call mid-JSON) must surface as an actionable message naming the cause + chunked recovery, not fall through the type assertions to a misleading "(empty path)" / "(empty comma

(t *testing.T)

// surface as an actionable message naming the cause + chunked recovery, not
// fall through the type assertions to a misleading "(empty path)" / "(empty
// command)". Checked for a file tool and bash to pin that the guard is generic,
// sitting before the per-tool switch.
